Question

What is the function of sulci and gyri?

Answer 1

Sulci:

1. Sulci are grooves on the brain's surface.
2. They are situated between the gyri.
3. They divide the cerebral cortex into gyri.
4. The sulcus that divides the left and right brain hemispheres is the medial longitudinal fissure.
5. Superior and inferior frontal sulci, superior and inferior temporal sulci, and central sulcus are examples.

Gyri:

1. The folds or bumps in the brain are referred to as gyri.
2. Gyri are grey matter structures located on the surface of the cerebral cortex that is made up of nerve cell bodies and dendrites.
3. The architecture and size of gyri differ from person to person, while some kinds of gyri are found in everyone.
4. Broca's gyrus is an example of a gyrus, which is a brain location that orchestrates speech production.
5. Superior, medium, and inferior frontal gyri, superior and middle temporal gyri, and precentral and postcentral gyri are examples.

The function of sulci and gyri:

1. Folding of the cerebral cortex results in the formation of gyri and sulci,
2. These folding segregate brain areas and enhance the surface area and cognitive abilities of the brain.
3. Gyri and sulci establish borders within and between the brain's lobes, dividing them into two halves.
