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 right vertical limb of the "H" defines the left and right functional lobes, while the left vertical limb of the "H" defines the right and left anatomical lobes. The horizontal line between the vertical limbs of the "H" represents the porta hepatis. The quadrate and caudate lobe lie superior and inferior to this line respectively.
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]

It then becomes a distinct invagination that lengthens towards the lateral sulcus and towards the longitudinal fissure [4] at approximately 22 to 23 weeks of gestational age. [ 5 ] Between 2 and 3 years of age, the landmark ‘Pli de Passage Frontoparietal Moyen’ (PPFM), which is a depression buried at the central part of the central sulcus ...
In neuroanatomy, the parieto-occipital sulcus (also called the parieto-occipital fissure) is a deep sulcus in the cerebral cortex that marks the boundary between the cuneus and precuneus, and also between the parietal and occipital lobes. Only a small part can be seen on the lateral surface of the hemisphere, its chief part being on the medial ...
Marie François Xavier Bichat (/ b iː ˈ ʃ ɑː /; [3] French:; 14 November 1771 – 22 July 1802) [4] was a French anatomist and pathologist, known as the father of modern histology. [ 5 ] [ a ] Although he worked without a microscope , Bichat distinguished 21 types of elementary tissues from which the organs of the human body are composed ...
The anterior median fissure of the spinal cord is a deep midline groove of the anterior spinal cord. [ 1 ] : 486 It divides the white matter of the anterior spinal cord nearly in two. [ 1 ] : 487 The spinal pia mater extends into the fissure to line the surfaces of the spinal cord.
