Name the following. (AS1)

Connective tissue presents in the brain.

i. Bone

ii. Blood

iii. Fibrous connective tissue.

Explanation: Bony structure called spinal cord surrounds the brain and prevents it from any injury or shock.

A large amount of blood is supplied to the brain so that there is no lack of oxygen and hence no damage to brain activity.

The brain along with the spinal cord is surrounded by three layers of fibrous connective tissue.
