Morphology

postcentral + gyrus

The compound is compositionally built: 'postcentral' means located behind the central sulcus and 'gyrus' denotes a fold of the brain, so together they straightforwardly refer to the brain fold immediately posterior to the central sulcus. Although the specific functional detail (sensory processing) requires anatomical knowledge, the referent and locational meaning are directly derivable from the constituents.

Etymology

Postcentral gyrus comes from two parts: postcentral meaning 'after the central' and gyrus meaning 'ridge'. So it is the ridge just behind the brain's central groove that receives touch signals from the body.
