Clevenger's fissure: found in the inferior temporal lobe of the brain; Collateral fissure: found in the inferior surface of the cerebrum. Fissure of Bichat: found below the corpus callosum in the cerebellum of the brain. Lateral sulcus or Fissure of Sylvius: separates the frontal and parietal lobes of the brain from the temporal lobe.
The sulci and fissures are shallow and deep grooves respectively in the cortex, that organise the brain into its regions. [2] A sulcus is a shallow groove that surrounds a gyrus or part of a gyrus. A fissure is a deeper furrow that divides the brain into lobes, and also into the two hemispheres as the longitudinal fissure. [4]
The longitudinal fissure also pays a role in the optic nerve tract. This is shown in (figure 4.) with the optic chiasm, which takes the nerve from the right eye to the left hemisphere and the left eye to the right hemisphere. The longitudinal fissure allows for this misdirection and crossover of nerves. [18]
The lateral sulcus (or lateral fissure, also called Sylvian fissure, after Franciscus Sylvius) is the most prominent sulcus of each cerebral hemisphere in the human brain. The lateral sulcus is a deep fissure in each hemisphere that separates the frontal and parietal lobes from the temporal lobe. The insular cortex lies deep within the lateral ...
A sulcus (plural sulci) is a deep groove that curves into the largest part of the brain, the cerebrum, and a gyrus (plural gyri) is a ridge that curves outward of the cerebrum. [1] The STS is located under the lateral fissure, which is the fissure that separates the temporal lobe, parietal lobe, and frontal lobe. [1]
The falx cerebri is a strong, crescent-shaped sheet of dura mater lying in the sagittal plane between the two cerebral hemispheres. [3] It is one of four dural partitions of the brain along with the falx cerebelli, tentorium cerebelli, and diaphragma sellae; it is formed through invagination of the dura mater into the longitudinal fissure between the cerebral hemispheres.
In neuroanatomy, the central sulcus (also central fissure, fissure of Rolando, or Rolandic fissure, after Luigi Rolando) is a sulcus, or groove, in the cerebral cortex in the brains of vertebrates. It is sometimes confused with the longitudinal fissure .
The superficial middle cerebral vein (superficial Sylvian vein) begins on the lateral surface of the hemisphere.It runs along the lateral sulcus [1] to empty into either the cavernous sinus, [1] [2] or sphenoparietal sinus. [1]
