Brain Internal Structures: Central Sulcus, Precentral Gyrus, and Postcentral Gyrus

Central Sulcus00:00:04

The central sulcus is a groove that separates the frontal lobe from the parietal lobe.

Precentral Gyrus and Primary Motor Cortex00:00:21

The gyrus in front of the central sulcus is known as the precentral gyrus, which houses the primary motor cortex.

Postcentral Gyrus and Primary Somatosensory Cortex00:00:33

The gyrus located behind the central sulcus is called the postcentral gyrus, and it contains the primary somatosensory cortex.
