Lateral sulcus or Fissure of Sylvius: separates the frontal and parietal lobes of the brain from the temporal lobe. Hippocampal sulcus: a sulcus that extends from the brain's corpus callosum to the tip of the temporal lobe. Horizontal fissure or Transverse fissure: found between the cerebrum and the cerebellum. Note that a "transverse fissure ...
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 (or cerebral fissure, great longitudinal fissure, median longitudinal fissure, interhemispheric fissure) is the deep groove that separates the two cerebral hemispheres of the vertebrate brain. Lying within it is a continuation of the dura mater (one of the meninges) called the falx cerebri. [1]
The commissural fibers or transverse fibers are axons that connect the two hemispheres of the brain. Huge numbers of commissural fibers make up the commissural tracts in the brain, the largest of which is the corpus callosum .
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.
The calcarine sulcus (or calcarine fissure) is an anatomical landmark located at the caudal end of the medial surface of the brain of humans and other primates. Its name comes from the Latin "calcar" meaning "spur". It is very deep, and known as a complete sulcus.
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 ...
The angle formed in turn creates a subarachnoid cistern, the cerebellopontine angle cistern. The pia mater follows the outline of the fissure and the arachnoid mater continues across the divide so that the subarachnoid space is dilated at this area, forming the cerebellopontine angle cistern.
