ZOO 3733C Study Guide - Final Guide: Postcentral Gyrus, Precentral Gyrus, Lingual Gyrus
Document Summary
Cerebrum has 4 lobes: frontal, parietal, temporal, occipital. Gyrus: meaty portion of cerebrum: pre-central gyrus: in front of central sulcus, post-central gyrus: behind central sulcus, superior, middle, and inferior temporal gyri on each side, superior, middle, and inferior frontal gyri on each superior side. Sulcus: another name for a groove inside the brain: pre-central sulcus: before pre-central gyrus, major sulcus we use to orient ourselves on top of cerebrum: central sulcus. Divides frontal lobe from parietal lobe: post-central sulcus: behind post-central gyrus, lateral sulcus: separates temporal and parietal. Fissure: really deep sulcus: longitudinal ssure: straight down superior portion, transverse ssure: between cerebellum and cerebrum. Lingual gyrus: on posterior side, looks like brain is sticking tongue out. Cuneus: kinda looks like a parrot: calcarine sulcus: divides lingual gyrus and cuneus. Pre-cuneus: following cuneus: parietooccipital sulcus: divides cuneus and pre-cuneus. Parecentral lobule: makes a square shape: contains central sulcus (stretches out, marginal sulcus: divides pre-cuneus and paracentral lobule.
