Question

Name the membrane that protects the brain and spinal cord.

Answer 1

Hint: The brain is the best protected organ in the body. It has multiple layers of protection like bony protection, membrane protection and finally fluid protection, starting with the first layer of protection being skull or cranium, which acts as a shield. The other layer of protection is the cerebrospinal fluid ( CSF ) that the brain and spinal cord basically float in

Complete answer:
The right side of the brain controls the left side of your body, and the left side of the brain controls the right side of your body. Brain not only controls all five senses ( taste, smell, sight, hearing and touch ), it is responsible for your emotions, thoughts and movement. Brain has three main parts:
-The cerebrum – it controls higher brain functions, it has four lobes, each with different tasks.
-The cerebellum – it controls balance , coordination, and fine muscle control.
-The brain stem – it controls things we do without thinking, like our heartbeat, breathing and swallowing.

Meninges are membranes that cover and protect the brain and spinal cord. There are three layers of meninges:
-Dura mater is the one which is closest to the bone.
-Arachnoid mater , which is loosely around the brain.
-Pia mater, which is closely attached to the brain and spinal cord surfaces.

The spinal cord starts at the brainstem and goes to the tailbone. Messages are carried from the spinal cord to the brain and from the brain and the rest of the body. Nerves extend from the spinal cord on each side and go to every part of the body.

Note: The brain and spinal cord are protected by bony structures – the skull and spinal column. The membrane which protects the brain has three layers. The main function of the meninges is to protect the central nervous system.
