Question

H-shaped grey matter is found in

• A. spinal cord
• B. cerebellum
• C. cerebrum
• D. medulla

Answer 1

The correct option is A spinal cord

The cross sections of human brain and spinal cord show two distinct regions:

• Gray matter: consists of neuronal cell bodies or soma
• White matter: consists of myelinated axons and appear white due to high fat content in myelin.

The difference between brain and spinal cord, with respect to the location of grey and white matter is given below:

• Brain: Grey matter is on the periphery and white matter is inside the periphery.
• Spinal cord: It has a butterfly structure or H-shape. The white matter is present outside the butterfly shaped structure and the H shape has the soma in it.
