I didn't get what u guys said about nerves being both sympathetic and parasympathetic at the same time. I thought an autonomic nerve can either be parasympathetic or sympathetic. For example, I thought a nerve like the vagus nerve (CN X) is strictly parasympathetic and the nerves of the thoracolumbar (T1 - L2) portion of d spinal cord are strictly sympathetic.
Secondly, I read that splanchnic nerves are the nerves that both carry afferent and efferent autonomic fibres to the viscera. Are these nerves part of the normal autonomic nerves or they are special nerves on their own?
cc: ikevin, ebsuguy.

you are correct talking abt thoracolumbar outflow (sympathetic) and craniosacral outflow (parasympathetic). Yet, sympathetic can return into its source to enter skeletal nerves to supply sweat glands, cutaneous blood vessels. Am just trying to clarify the fact that nerves can carry more than one fiber. But regarding splanchnic nerves, they usually carry more than one fiber to an organ.

ebsuguy:
ikevin is right as to their termination-the viscera i.e the organs. The sympathetic NS has a thoracolumbar spinalcord origin while the Parasympathetic NS originate from nuclei in the brain and Sacral region of the cord.Hence,they do not have a common origin. Rather what ikevin said about the nerve bundle is correct.Both the sympathetic fibers and the parasympathetic fibers run in the same nerve to supply the organs.

nice one brof. Your inputs on the page are on point man.

ebsuguy:
Simply put,they are autonomic nerves arising from the spinal cord that do not relay in the paravertebral ganglion.

alright. The term splanchnic refers to viscera (internal organs). Now splanchnic nerves refers to nerves concerned with viscera. In the nerves, there are autonomic fibers ( parasympathetic and sympathetic) and viscera afferent (sensory) fibers. All these help in passing stimulation to and fro the viscera. Regarding ur questn abt origins. From my knowledge so far, the term NERVE is not a single entity, it is like a passageway, it contains different fibers, so a nerve can contain sympathetic, parasympathetic and somatic fibers all about their differential functions. I am open to counter info, .

DrAmanda:
Yes, they do
Uhm I really don't know the exam style
I think ikevin should know better
You'll hear from him soon

Cc: ikevin

aite. Exam is based on English, mathematics, physics, chem, bio and some current affairs. Eng and maths makes about half of the questions. It depends on spaces available, let's just say from 7-10. Do not be alarmed, just try to read hard. Hoping to welcome you here at Delsu. #success.

AbuadStudent:
you totally nailed it! That guy's question had me thinking seriously. Although what you just said is basically the tubuloglomerular feedback.But this basically occurs when there is a decreased Gfr. As to How just "Hyponatremia" would stimululate a decrease in GFR directly is still unclear to me..which led to my initial confusion. dope answer tho!

yep very dope answer. Also, the resultant decrease ECF volume due to loss of osmotically-active substance (Na) would lead to low blood pressure which induces the JG-cells of the afferent arterioles to secrete renin which also brings about the renin-angiotensin mechanism. My mind didn't even go towards macula densa while posting the question. He just pasted it on my mind. Nice.

Vhictoria:
Hello guys. Im new here. I just wanna know if sumone in delsu(medicine and surgery) can tell me more about it. Thanks

if it is about that rumored NUC directive, Delsu has not yet released any info regarding that. What else do you want to know?

Thewhizzkid1:
Pls can you still remember the topics u did in histology?
cc: ikevin, jargo89, ebsuguy.

1st semester: Basic tissues (epithelial, muscular, connective and nervous tissues).
2nd semester: respiratory sys, GIT and cardiovascular sys.

1. After being thrown from a motorcycle moving
at high speed, a 16-year-old female was
found to have a paralyzed right pectoralis
major muscle. Which set of movements at
the shoulder joint would be found greatly
weakened?
Abduction and extension
Abduction and lateral rotation
Adduction and flexion
Lateral rotation and extension
2.After a jarring blow to the left anterior
shoulder region, a young field hockey player
was told by an examining physician that she
had a muscle tear that resulted directly from
the superolateral distraction of a fractured
coracoid process. Which muscle was torn?
Deltoid
Pectoralis major
Pectoralis minor
Serratus anterior
Subclavius
3. During a fight a man is stabbed in the lateral
chest beneath the right arm. The wound does
not enter the chest cavity. Physical
examination reveals that the vertebral (medial)
border of the patient's scapula projects
posteriorly and is closer to the midline on the
injured side. On return visit the patient
complains that he cannot reach as far forward
(such as to reach for a door knob) as he
could before the injury. The nerve injured
which caused these symptoms is the:
axillary
long thoracic
musculocutaneous
radial
suprascapular
4. While observing a mastectomy on a 60-year-
old female patient, a medical student was
asked by the surgeon to help tie off the
arteries that supply the medial side of the
breast. The artery that gives origin to these
small branches is the:
Internal thoracic
Musculophrenic
Posterior intercostal
Superior epigastric
Thoracoacromial
5.A woman with breast cancer subsequently
develops metastases in her vertebral column.
The most direct route for spread of the tumor
to the vertebral column was via:
branches of the cephalic vein
branches of the lateral thoracic vein
branches of the thoracoacromial veins
lymphatic vessels draining into the axilla
branches of the intercostal veins
6. A man suffers a penetrating wound through
the anterior axillary fold, with resulting
damage to one of the main terminal branches
of the brachial plexus. Among the effects is a
significant weakening of flexion of the elbow.
One or more other effects to be expected is
(are):
a)Loss of cutaneous sensation on the tips
of several fingers
b)Only loss of cutaneous sensation on the
anterolateral surface of the forearm
c)Only weakening of flexion at the shoulder
Weakening of flexion at the shoulder and
d) loss of cutaneous sensation on the
anterolateral surface of the arm
e)Weakening of flexion at the shoulder and
loss of cutaneous sensation on the
anterolateral surface of the forearm
7. A person sustains a left brachial plexus injury
in an auto accident. After initial recovery the
following is observed: 1) the diaphragm
functions normally, 2) there is no winging of
the scapula, 3) abduction cannot be initiated,
but if the arm is helped through the first 45
degrees of abduction, the patient can fully
abduct the arm. From this amount of
information and your knowledge of the
formation of the brachial plexus where would
you expect the injury to be:
axillary nerve
posterior cord
roots of plexus
superior trunk
suprascapular nerve.
Good night u all.
Zellie I've tried sending the textbooks but I haven't been able to get them through. The files are large and they don't upload for me to send. I was thinking of sending u the links were u can download directly since u'll still need to download even after I send the documents to ur email. Just decided to tell u first if it will be okay by u.

Mehn!!!I did upper limb early last year, yet I would give it a try.

Wishing all medical students on this forum a blessed new year. Also wishing aspirants success so we can fully welcome you guys on board.
Now to my question. Sodium is not really a stimulus for the release of Aldosterone (Potassium has a strong effect). What would actually explain the release of Aldosterone from the zona glomerulosa of the Adrenal cortex in relation to severely reduced Sodium concentration in the ECF (blood plasma).

Gudmrn medics n aspirants hop u all had a nice Xmas celebration. I really need your encouragement at this point, I've enrolled for jamb again for medicine but I just can't explain what am going through to you guys....I'm really getting tired of this chase, I just feel there is too much to be done in no time. My 100lvl first semester exam is by February and jamb exams would be kicking off at that time. I'm so confused, I've always been able to draw inspiration from within me but this time I need you all.

one thing is definite. If you truly want it, then you would get it. At the end of the day, only you would decide how low you can go to prepare. #Success .

emysocio:
Is 10 points OK for mbbs in delsu through DE??
Cc: dsurgeon

all you just need to do is to get a very high score. 65-70 would just be good enough. Besides, what state are you from? Wishing you the best of lucks.

@drss, You keep going everywhere to paste the same thing. You guys need to calm down. You've started referring to Nigerian soldiers as Zoogerians uhn. Yet you want us to take you seriously. You can pass your message without insults, just do it intelligently okay.

I duff my intellectual hat to anybody who comfortably answered the numerical aspect. They should have just said Guess the numerical part. Lol, by the time you try to calculate 5 questions time go just finish.

I answered the verbal well, even revised sef. Numerical chei!!! Na guessing sure pass..

The numerical reasoning was crazy!!!!!

chusks:
Boss thanks very much, greatly appreciated!

pls can you send me too-kelvinreal_oo1@yahoo.com thanks.

estybae:
Hi everyone, pls which of these schools are best for medicine DELSU or NDU

good evening, if you're a deltan I think you should just pick Delsu. If not, choose your state sch if it offers medicine, if not check for federal schools with a higher level of merit list. If you keep checking for which school offers the best, my dear........just my humble thoughts.

Drguzzykola:
My bros,, don't be so surprise medics aren't replying all this biological questions, 80% of medics here are now medically inclined ,Chewing Anatomy><Pharmacology and co inside bush*open teeth*,,, they forgot the old biology jamb days ,, its been long , I ll wish u search and like some biological pages on Facebook, u get a better answer there.
Suppose ur questions are like( what causes heart failure , diabetes and ko ), hmmm I trust my Oga @d top, they will chew it for u.
The help aspirant can benefit here are motivating passion, making the right decision of which school to choose , listen to medical tongues that ll challenge /inspire u, et ' al.

lol!!!as in ehn, where would I start from? Anyways, its all good.

steppin:
Hahahaha! This boy na Yoruba boy .... Na dem dey get this kain malnourished head. Lol

including otedola?

To all ProNigerians, I really think it is high time we stop arguing with these guys. Just let them be, let them say what they feel like as long as they so wish. Let us be concerned about issues with motherland Nigeria. Besides, why are you guys on nairaland, can't you guys create biarand or something and carry all your discussions there. It is now boring.

datguru:
I have a prophecy....

I was in a trance and I saw Buhari feeling disappointed with himself because he is not fulfilling his promises to Nigerians. He has good intentions but the cabal around him won't let him.

All of a sudden he has serious problem with his party men and the cabal. He then saw that his time is up and if he eventually dies, the same cabal will take over.

He then decided to call for a referendum and divide the country for good

no matter how much you hate someone especially Buhari who doesn't even know you directly. You shouldn't wish someone dead, you lack power over life and should wish someone the opposite. Yet, Nigerian youths continue to disappoint.

bronzegoddess:
I love SR

yet I must express my reservations about SR, the manner they exchanged issues with the Senator Bruce expressed their amateur and unofficial approach to issues. Although they seem unalloyed to a good extent. The more you look, the less you see. Everything like someone said on this thread is a mere magic for the Nigerian mob to feast on. The real issue is to force these guys to develop Nigeria . Being a while "medusa", felt I should holla.m.

Good day house, wow!!!I am learning o. Nice

Greekgoddess:
Good evening

wassup Goddess? Hope your day went well...really nice of you to holla. Would it be okay to chat via whatsapp?

Greekgoddess:
Hmmmmm Medusa

My day was stressful

Greekgoddess:
Yes

Greekgoddess:
Am not into greek myths

Nd my name is greekgoddess

lol, the name on your National I D. tell me your name nau.

laryom1:
I missed this... But let me add spices

The production of NADPH is to actually reduce the oxidized glutathione being produced in the RBC, catalyzed by Glutathione reductase. Product of the reaction actually removes H2O2 as radicals produced by the dissociation of H2O2 cannot be removed singly and it is also catalyzed by glutathione peroxidase(selenocysteine active site).
If that doesn't happen as in the deficiency of G6PDH, accumulation of H2O2 in the cell would have an oxidative effect on the cell membrane.

nice additive boss.

Greekgoddess:
True we all r not perfect, but i don't know y u guys like taking it out on we ladies

I personally do not do that to a silly level, you didn't reply d greek part n name.....

Greekgoddess:
Really?

let us be sincere here, no human (male/female) walking the face of this earth is perfect, not even the dead. I remember caderver sessions where my class mates complain about this or that about a dead body. So, the point is we all have flaws, either imposed by nature or the ones we developed. Let's just appreciate the ones we got. Wassup GreekGoddes, are you into Greek myths because I am into them a lot. What's ur real name?

niggi4life:
so many of these ladies can not even afford to buy ordinary pant and bra for themselves without asking their BF, yet they open their mouth and call some guys broke dude.

Dbrainiac1:
I salute you. These books are so 'dense'. Esp Ganong

but really, Ganong is like a revision book. Not a book you pick up to start understanding, guyton explains then you use Ganong to revise. Sometimes, Guyton's story is just too much so I use Ezeilo altho the book is very "dense", I use it the revise with Ganong. Although I would be spying guyton all along..lol.. I wonder why a lot of people dread Ganong. The book is straight forward. Greetings
