Short answer questions

Sulcus

Sulcus

A sulcus (plural: sulci) is a shallow groove or depression on the surface of the brain. Sulci separate the brain's convolutions, known as gyri.

Fissure

A fissure is a deeper, more prominent groove than a sulcus, and it extends further into the brain's structure. Fissures often divide the brain into distinct functional or anatomical regions.

Gyrus

A gyrus (plural: gyri) is a ridge or elevated fold on the brain's surface. Gyri are separated by sulci and increase the surface area of the cerebral cortex, allowing for more neurons to be packed into a limited space.

Longitudinal fissure

Also known as the interhemispheric fissure, it is a deep groove running along the midsagittal plane, separating the brain into its left and right cerebral hemispheres. It extends from the front of the brain to the back.

Sylvain fissures (lateral sulcus)

Located on the lateral sides of the brain, the Sylvian Fissures are prominent fissures that separate the temporal lobe from the frontal and parietal lobes. They run horizontally from the anterior to the posterior brain, starting near the frontal lobe and curving up towards the parietal lobe.

Central sulcus

This sulcus is a prominent landmark located in the middle of the brain's lateral surface, separating the frontal lobe from the parietal lobe. The precentral gyrus (primary motor cortex) and postcentral gyrus (primary somatosensory cortex) are located in front and behind the central sulcus, respectively.

Fusiform Gyrus

The fusiform gyrus is a part of the temporal lobe and is located in the ventral occipitotemporal region of the brain. It is present on the inferior surface of the brain and stretches from the inferior temporal gyrus to the occipital lobe. It is associated with the recognition of faces, objects, and colors.
