The central sulcus is a prominent landmark of the brain, ... As motor functions develop, it is expected that the shape of the central sulcus will change.
On the basis of function: A limiting sulcus separates at its floor into two areas which are different functionally and structurally e.g. central sulcus between the motor and sensory areas. [2] Axial sulcus develops in the long axis of a rapidly growing homogeneous area e.g. postcalcarine sulcus in the long axis of the striate area.
In biological morphology and anatomy, a sulcus (pl.: sulci) is a furrow or fissure (Latin fissura, pl.: fissurae). It may be a groove, natural division, deep furrow, elongated cleft, or tear in the surface of a limb or an organ, most notably on the surface of the brain , but also in the lungs , certain muscles (including the heart ), as well as ...
The opercula lie on the precentral and postcentral gyri (on either side of the central sulcus). [3] The part of the parietal operculum that forms the ceiling of the lateral sulcus functions as the secondary somatosensory cortex.
The insular cortex is divided by the central sulcus of the insula, into two parts: the anterior insula and the posterior insula in which more than a dozen field areas have been identified. The cortical area overlying the insula toward the lateral surface of the brain is the operculum (meaning lid). The opercula are formed from parts of the ...
The borders of this area are: the precentral sulcus in front , the medial longitudinal fissure at the top , the central sulcus in back (posteriorly), and the lateral sulcus along the bottom . This area of cortex, as shown by Wilder Penfield and others, has the pattern of a homunculus. That is, the legs and trunk fold over the midline; the arms ...
The human primary motor cortex is located on the anterior wall of the central sulcus. It also extends anteriorly out of the sulcus partly onto the precentral gyrus. Anteriorly, the primary motor cortex is bordered by a set of areas that lie on the precentral gyrus and that are generally considered to compose the lateral premotor cortex.
The postcentral sulcus of the parietal lobe lies parallel to, and behind, the central sulcus in the human brain. (A sulcus is one of the prominent grooves on the surface of the brain .) The postcentral sulcus divides the postcentral gyrus from the remainder of the parietal lobe .
