Question

The grey matter of brain is formed by __ of neurons and is folded into __ and __ .​

Answer 1

Answer:

The grey matter of the brain is formed by cell bodies of neurons and is folded into gyri and sulci.

Explanation:

Grey matter contains most nerve cell bodies in the brain. Grey matter includes areas of the brain involved in muscle and sensory perception such as vision and hearing, memory, emotions, language, and self-control. The neurons in the grey matter are connected to various parts of the brain by a layer of nerve known as white matter, which lies immediately below the surface of the grey matter. The purpose of the gyri and sulci is to increase the effective surface area of the brain which is essential for proper functioning as it allows for more neurons to be present in contrast to a smooth brain.
