Question

What are the gyri?

1) Folds on the cerebral cortex
2) Sheets arranged in folds on the cerebral cortex
3) Parts of the brain
4) Nerve cells in the cerebral cortex

Answer 1

Gyri are the ridged or raised portions of the cerebral cortex, which are essential in defining the brain's functional regions and contribute to higher neurological functions. The cerebral cortex is involved in higher functions of the nervous system such as memory, emotion, and consciousness.

Step-by-step explanation:

The gyri (singular: gyrus) are folds on the cerebral cortex, the outer layer of gray matter that covers the forebrain. These gyri and the grooves between them, known as sulci (singular: sulcus), create a pattern of wrinkles that are critical for defining the different functional regions of the brain. The cerebral cortex is involved in higher functions of the nervous system such as memory, emotion, and consciousness.
