Question

What are the types of cells present in gray matter?

Answer 1

Hint: It is a major component of the central nervous system . It consists of numerous cell bodies and few myelinated axons. It includes the region of the brain involved in muscle control, and sensory perception such as seeing, hearing memory, emotion speech, decision making and self –control.

Complete answer:
To answer this question, we need to know about tissues present in the central nervous system.
The central nervous system is made up of two types of tissues: Gray matter and White matter. The Gray matter comprises the regions in the brain and spinal cord that consists predominantly of cell bodies of nerves cells(neurons) and neuropil (dendrites and unmyelinated axons). Axons extend from neural cells' bodies, carrying signals between those bodies that are unmyelinated means they are not covered with whitish –colored, fatty protein called myelin.

Gray matter is also found in glial cells (astroglia and oligodendrocytes) and capillaries. The glial cells help to transport nutrients and energy to the neurons as well as influence how the neurons function and communicate. The gray matter is the site of coordination between nerves of the central nervous system which contain high density of nerve cell bodies.
Therefore, Gray matter is composed mainly of the cell bodies of neurons, branching dendrites and glial cells.

Note:-
The spinal cord has a central core gray matter, which has a shape of a butterfly when cut across. And there are clumps of gray matter called nuclei making up such structures as the hypothalamus, the thalamus of basal ganglia. Human brain consists of 60 % of white matter and 40% of gray matter. Gray matter isn’t actually gray in color at all; it is healthy pink due to the blood that’s constantly flowing through.
