Normally as a human, one would want to know how certain activities in the body are done and the body organ or system responsible for those actions. I've put this article together to help us with that problem, and as you'd expect, we'll be using the mammalian system as an example. The mammalian nervous co-ordination is divided in two, namely the nervous system and the endocrine system. Messages or informations/ impulses in the endocrine system are passed as hormones in the blood stream while informations in the nervous system are passed as electrical impulses.
The nervous system is controlled by the brain and the spinal cord, while the endocrine system is controlled by the pituitary gland. However, the nervous system responds faster to situations as it takes few minutes to respond to stimuli and in some cases less than a second(reflex actions). But for the endocrine system, response is slow and lasts longer.
The Nervous system is divided in the Central Nervous System(CNS) and the Peripheral Nervous System(PNS).
Central Nervous System
The CNS consist of the brain and the spinal cord. The brain which is a major part of the CNS is divided into the fore brain, mid brain, and hind brain. The fore brain is subdivided into cerebrum consisting of two hemispheres(the right and the left hemispheres protected by corpus collosum and partially separated by the median fissure) and the olfactory lobes located auteriorly at the fore brain. The fore brain is responsible for involuntary actions like movement of the leg, speech etc. While the olfactory lobes is responsible for making the animal aware of the environment. The olfactory lobes is connected to a sense organ, the nose.....Read full article
