Document Summary
Lateral: away from midline: medial: towards midline, dorsal: towards top/back, ventral: towards bottom/belly o sagittal: a mid sagittal cut means the exact middle (between the eyes, rostral/anterior: towards the beak, front, caudal/posterior: towards the tail, back o horizontal. The cerebral aqueduct is a long, tube like structure that connects the third ventricle to the fourth ventricle (which sits between pons/cerebellum: csf produced by the choroid plexus highly vascular tissue that protrudes into ventricles and produces csf, csf is 50% replaced every three hours (the half life, csf leaves the fourth ventricle and flows through subarachnoid space all around the brain before it is absorbed into the blood supply. On the surface of the cerebral hemispheres is the cerebral cortex, which is highly convoluted with o sulci (small grooves) o fissures (large or major grooves) o gyri (ridges between sulci or fissures: outermost portion of cerebral cortex = gray matter.
