Question

Gray matter consists of the ______ of neurons

Answer 1

Gray matter consists of the cell bodies (soma) and dendrites (branches) of neurons or the nerve cells.

Explanation

The absence of myelinated sheaths of the neurons in gray matter gives its gray color. Along with soma and dendrites, gray matter also consists of axon tracts, neuropil, glial cells and blood capillaries. The volume of gray cells correlates with a person’s skills and abilities.

Both the brain and the spinal cord contains gray matter. Gray matter is involved in a number of brain activities like thinking and memory, seeing and hearing, decision making and self-control etc.

Answer 2

Gray matter consists of the unmyelinated axons of neurons.

Step-by-step explanation:

The outer layer of the brain consists of the grey matter and white matter. The grey matter gets its name by the pinkish grey colour obtained by the greyish colour of the neurons and the red colour from the capillaries.

The grey matter consists of the dentrites, axons and cell bodies and this is essential for memory, attention and learning.

The unmyelinated axons are not covered by the fat protein myelin and these axons carry signals.They are the ones to help the processing of information in the brain.
