The anterior interventricular sulcus (or anterior longitudinal sulcus) is one of two grooves separating the ventricles of the heart (the other being the posterior interventricular sulcus). They can also be known as paraconal interventricular groove or subsinosal interventricular groove respectively.
1: Sphenoidal limbus (anterior margin of the chiasmatic groove) 2: Posterior borders of the lesser wings of the sphenoid 3: Dorsum sellae of the sphenoid bone 4: Superior borders of the petrous part of the temporal bone. 5: Groove for transverse sinus of the occipital bone
The anterior cranial fossa is a depression in the floor of the cranial base which houses the projecting frontal lobes of the brain. It is formed by the orbital plates of the frontal, the cribriform plate of the ethmoid, and the small wings and front part of the body of the sphenoid; it is limited behind by the posterior borders of the small wings of the sphenoid and by the anterior margin of ...
These form the ventricular system of the brain: [8] The neural stem cells of the developing brain, principally radial glial cells, line the developing ventricular system in a transient zone called the ventricular zone. [9] The prosencephalon divides into the telencephalon, which forms the cortex of the developed brain, and the diencephalon.
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]
Interventricular groove may refer to: Anterior interventricular sulcus , one of two grooves that separates the ventricles of the heart, near the left margin Posterior interventricular sulcus , one of the two grooves that separates the ventricles of the heart, near the right margin
The interventricular foramina are two holes (Latin: foramen, pl. foramina) that connect the left and the right lateral ventricles to the third ventricle. [1] They are located on the underside near the midline of the lateral ventricles, [2] and join the third ventricle where its roof meets its anterior surface. [3]
It is also responsible for control of blushing, [1] defecation and urination. It includes portions of the frontal and parietal lobes : [ 2 ] The anterior portion of the paracentral lobule is part of the frontal lobe and contains a little portion of Brodmann's area 6 (SMA): this is because the paracentral sulcus (branch of the cingulate sulcus ...
