explain about human neural system...

Answer 1

here is your answer

_______________________________

Neural system :-

★ neural system detect, perceive and transmit the nerve impulse to the different body organ

★ firstly is observed in coelenterates as a nerve fibre but in orthopods it is complex form comparative nerve fibre and ganglia

★ in vertebrates it is more developed and forms CNS and PNS

★ CNS comprises brain and spinal cord while PNS comprises cranial nerves and spinal nerves

★ PNS has two types of nerve that is called
# Afferent nerves
# Efferent nerves

★ Afferent nerves transmits the impulse from tissue organ to CNS and if efferent nerves sends the impulse from CNS to tissue / organ

Hi Friend 

Here's ur ans :- 

✴ The system made of nerve Cells is called as nervous system Or neural System.

• Function of Nervous system is to co-ordinate the activities of our body !

• Human nervous system receive information from the surrounding , process it , interprets it and then respond accordingly.

☢ Nervous system is made up of special cells called as neurones.


• Neurones is the structural and functional unit of the nervous system.

• A nerve cell have Three parts :-

i ) Cell body ( Cyton )

ii ) Dendrites

iii ) Axon


° There are three types of neurones :-

i ) Sensory neurones :- It transmit impulses from the sensory cells towards the central nervous system.


ii ) Motor neurones :- It transmit Impulses from the Central nervous system towards effectors .

iii ) Relay neurones :- It occur in the central nervous system where they serve as links between other neurones.


☣ Part of human nervous system

• Central nervous system

It contain brain and spinal cord !!

• Peripheral nervous system

It consists of all the nerves of body like cranial nerve , spinal nerve etc.

Peripheral nervous system can be divided into two parts :-

i ) Voluntary nervous system :- It is under Voluntary control from brain .

ii ) Autonomic nervous system :- It operates automatically or involuntary.
