Question

Spinal cord and its relation to the nervous system

The main pathway through which is the information is transfer and connected in the brain and nervous system is the spinal cord.

spinal cord is made of nervous tissue and its structure is like long, tubular and thin. It is elongated from the medulla oblongata region of the brain system till the vertebral column region of lumbar.

The spinal cord helps the body in the following function like it help to control the blood pressure level, body function like breathing, in the moving parts. The message when the body moves is received by the spinal cord and then sensations are felt by the human body.

The spinal cord depends upon the nervous system like the signal which sends from the brain and any type of damage in the spinal cord affect the nervous system. The central nervous system function is to control the body function and it consists of the spinal cord and brain. Nervous system has around 100 billion neurons that are present in the brain and the spinal cord.

The spinal cord helps the nervous system in sending signals and in
controlling the body functions.
The life structures of the spinal cord itself, comprises of a large number of nerve strands which transmit electrical data to and from the appendages, trunk and organs of the body, back to and from the brain. The brain and spinal cord are alluded to as the Central Nervous System, while the nerves interfacing the spinal cord to the body are alluded to as the Peripheral Nervous System. The nerves inside the spinal cord are gathered in various packs called Ascending and Descending tracts.

Answer 1

The nervous system of our body consists of two parts :

a) central nervous system

b) peripheral nervous system

Central nervous system consists of brain and spinal cord.

Peripheral nervous system consists of the spinal and cranial nerves.

The functional unit of nervous system is neuron. There are about 100 billion neurons present in the body.

The electrical data is transmitted from the appendages, trunk and body organs via nerves to the spinal cord.

The spinal cord is a long, tubular, thin structure that extends from the base of the brain to the filum terminale in lumbar region. It depends upon the nervous system that is any damage to spinal cord affects the nervous system. The spinal cord helps in sending signals and controlling body functions.

The data is also conveyed to the brain(main processing area) via spinal cord .The signals are transferred to the brain via ascending tracts of spinal cord and signals are transferred from the brain via descending tracts of spinal cord.

The spinal cord helps the body in various functions like controlling blood pressure, breathing and movement.
