Some of the interesting medical facts i know are related to the musculoskeletal system.....which means the muscle and skeletal system.....



(1).....There is about 1kg of calcium in 206 bones.
Compact (cortical) bone specimens have been found to have tensile strength in the range of 700–1,400 kg per square cm (10,000–20,000 pounds per square inch) and compressive strengths in the range of 1,400–2,100 kg per square cm (20,000–30,000 pounds per square inch). .

These values are of the same general order as for aluminum or mild steel, but bone has an advantage over such materials in that it is considerably lighter. 


Femur is the most strongest bone of the body yet it is hollow and 75% water.Femur is the longest bone of the body making 1/4th of the total body length while Stirrup(an ear bone) is the shortest bone making it about 1/10th of an inch.Teeth are even stronger than femur but they are not considered bones.

Hyoid( a bone in the neck region ) responsible for making complex vocal sounds is the only bone without joints



.Bone is comparable to steel in strength but amazingly it is more elastic than steel.

Bone protects a very crucial blood forming structure called Bone Marrow which makes about 2 million blood cells in a second.

Humans and Giraffes have some number of bones in their necks.

Over a period of 7 Years our bone is replaced by a completely new bone by a process called resorption.





54 bones are present in both hands and wrists and 58 bones are present in both feet out of total 206 bones.The only bone that is full grown in the body at the time of the birth is the ear bone.





Have you ever heard of disease called Disease of bone disappearance. Yes the bone totally disappears in Gorhams Disease and all that is left in the xray after the fracture of the bone is a void space because the bone is totally resorped.





A block of bone can carry about 9 tons of weight. A cubic inch of a bone can bear about 19,000 I lbs of weight.



Foot bones are the most fragile bones.



If a rib is removed it can regenerate itself in 3 months.



There are 230 joints in the human body discovered till to-date.

Op you're doing a nice job. There's just one problem, Nairalanders or lemme say Nigeriams in general aren't really into educative stuffs. They prefer enticing headlines like 'cossy orij.. Shows cleaveages in new photos'. Watch how they troop into the thread. I was running an infographic too on tech. Turnout was poor!

Did you know that humans, birds, and bats have the exact same types of bones in their forearm?

18. The most suitable space for cancerous cells to metastasize is Bones.



This is gross but still its worth knowing that panda is the animal who has a bone in its penis.It is called the baculum.




Finger nails grows 4times faster than toe nails.




A small piece o Tibia,a leg bone ,can carry the weight of a car.Believe it or not.

screw attached to a single cortex of the femur can carry a weight of 3 adults

Vultures’ digestion may hold the key to preventing biological warfare.

Vulture stomachs can process and sterilize anthrax spores, and when they eat botulism-infected carcasses, the bacteria gets killed.
When vultures eat dead rodents containing hantavirus, the disease ends in their system, and they’re fine.



Normal Vital signs in human adults:

Temperature
Rectal (most accurate) / Aural (the ear) is 99.6 F/ 37.7

Oral is 98.6 F / 37 C


Blood pressure: systolic (100-120 mmHg), diastolic below (80 mm Hg)


Pulse: normal resting pulse can range between 60-100 beats per minute. This number is decreased in athletes.

The immune system is very complex and can fight many diseases on its own.

The definition for haploid is often written

“ Half number of chromosomes”

Is Wrong!



The correct one is

“ One complete set of chromosomes which has half number of chromosomes than diploid set”



Organisms are composed of cells. The cell, therefore, is the most basic unit of life. However, an organism is not reducible to individual cells. That is to say that a living organism depends on the intricate ways in which its cells differentiate, specialise and interact.



Every aspect of a cell is governed by the expression of its collection of genes. Genes are composed of nucleotides that are organised into a molecule known as DNA. DNA is considered to be the basic unit of information in biological systems.




DNA codes for proteins. This is only a minority of the whole strand, however, and the rest was considered “junk”. The junk (non-coding) sections of DNA also serve important purposes, such as regulation of gene expression. There are many other genetic interactions that are just as important as the coding sections in determining how an organism develops.

Evolution:

DNA replication is imperfect. The presence of mutagens, faulty genetic repair mechanisms and the sheer number of replications means that mutations inevitably occur. Some prokaryotic organisms can also exchange genetic material with each other.



Viruses can also introduce changes to an organism’s DNA. Since the advent of sexual reproduction, DNA is also being altered at each instance of reproduction. All of these things mean that DNA changes over subsequent generations.




This also means that a population will have variation, differences between each individual. Some changes are detrimental to an organism’s survival. Some changes may improve an organism’s survivability. As long as an organism is a reproductive success, its genes will stand a chance of being passed on.




Environmental factors will affect an organism’s ability to reproduce. These are known as selection pressures and will, in effect, filter a (varied) population for those best able to survive those pressures. This is known as natural selection.There is competition within each niche between organisms that fill that niche. In order to survive, other organisms must either fill other niches or populate a different environment.


This process has continued for an unimaginably long period over an even greater number of generations of organism that must fill niches that are always changing.This process is more than capable of producing the massive spectrum of organisms that exist today. Each organism is well-adapted enough to survive and successfully reproduce in its niche. There is no such thing as a “pinnacle of evolution”

True, I had to abandon mine. just pray yours gets to FP. I'm following though, nice work.

A new born baby's head when touched , one feels a part of the head which is soft to to touch and a beating pulse is also felt..

This part of the skull( which is the baby's head ) is called FONTALLES...

It function is to allow for the head of the baby to pass through the pelvic of the mother during delivery..

After few months the soft is hardened up....
