Anatomy and Cell Biology 3319 Lecture Notes - Lecture 5: Pyramidal Cell, Lingual Gyrus, Prefrontal Cortex
Document Summary
Know the names and locations of the major sulci, fissures and the name, location and border of the lobes of the cerebral cortex. Cerebral hemispheres make up the vast majority of the brain: distinguishes the primate brain (specifically humans) from other species. Cerebral cortex (gray matter: superficial cortical layer of gray matter containing neuronal cell bodies. Cerebral white matter: deeper layer of white matter containing fibers (axons) connecting cells bodies to other cortical areas and the rest of the brain. Deep gray matter: basal ganglia deepest layer of large collections of neuronal cell bodies, so the basal ganglia is a part of the cerebrum. 83% of total brain mass sensory and motor areas association areas: perception and interpretation involved in cognitive function. Gyri (ridges) and sulci (grooves) provide anatomical separation of areas: gyri found between two sulci. Want the most superficial gray matter possible: sulci and fissures allow for extremely large surface of cortical layer within small space.
