HLSC 2400U Chapter Notes - Chapter 1: Cerebral Cortex, White Matter, Frontal Lobe
Document Summary
Overview: functional anatomy of the cerebrum, anatomical features of the basal ganglia, anatomical features of the cerebellum, different regions of the brainstem, physiological mechanism behind concussions. Divided into folds and indentations (gyri bumps sulci grooves fissures deep grooves) Cerebral cortex is located on the surface of the cerebrum. White matter is deep inside, contain myelinated axons of neurons. Grey matter are on the surface of the cerebrum, contain cell bodies. The folds in the cerebellum are much smaller, allowing for more surface area, thus more neurons. All of the nerves that travel from one hemisphere to the other travel in the corpus callosum. Holds the left and right hemispheres of the brain together. Controls movement, important for the motor system. Laterally on top of the cerebral hemisphere. Differentiates the frontal from the parietal lobe. Differentiates frontal/parietal lobe from the temporal lobe. The limbic lobe controls emotion and surrounds the corpus callosum.
