Question

parts of nervous system and there functions ​

Answer 1

The nervous system consists of 4 main parts:-

√Brain

√Spinal cord

√Sensory organs

√ Nerves (spinal and cranial nerves )

*Functions of different parts of nervous system :-*

1) *BRAIN*

•It is the centre of the nervous system

•Being a complex organ it controls memory, emotions, speech, movement, sensations and awareness.

2) *SPINAL CORD*

•It conducts messages from skin and muscles to the brain

•It directs our body voluntary muscle movement

3) *NERVES*

•Send electrical signals from one cell /gland/muscle to other.

•Interpret the information and control our response

4) *SENSORY ORGAN*

•Collects information from sensory receptors.

Answer 2

The brain is at the heart of the neurological system. The brain processes the information from your eyes and hearing, and if you decide to move, your brain instructs your muscles to do so.

Anatomy of the CNS and PNS

• Your brain sends small electrical messages to your muscles via your nerves, which causes them to move.
• Do you remember how long neurons may get? Nerves, on the other hand, are essentially a bundle of those lengthy neurons clumped together.
• Each of those extremely long neurons delivers a little electrical shock to your muscles, causing them to contract and move your body.
• Although the nervous system is extremely complex, it may be broken down into two distinct sections.
• Inside your skull and vertebrae are your brain and spinal cord (the vertebrae make up your backbone).
• When you have an accident, these bones safeguard your CNS.
• The Peripheral Nervous System (PNS) is another component of the nervous system (or PNS).
• The nerves that go to and from the CNS make up the majority of the PNS. The PNS, unlike the CNS, is not protected by bony structures.
• Have you ever come upon your "funny bone"? You squeezing one of your arm's nerves caused that strange sensation. Part of that nerve
