EXSC 224 Lecture Notes - Lecture 7: Skeletal Muscle, Meninges, Cerebral Peduncle
Document Summary
Myelinated fibers and their tracts - come to or leave the cerebral hemispheres. Connects gray matter of the two hemispheres. Know what happens when you sever the corpus callosum (epilepsy) etc. Connect different parts of the same hemisphere. Connect gyri within the same hemisphere, and can be in different lobes. Can connect the sensory to the prefrontal cortex. Connect the hemispheres with lower brain or spinal cord. Going to and from the cortex of the cerebral hemisphere. Associated with either primary motor or primary sensory area. Sensory are pretty short - project from thalamus to primary sensory cortex. Functionally associated with the subthalamic nuclei (diencephalon) and the substantia nigra (midbrain) Regions work together and play a role in motor function. It is in step with receiving information that then is relayed from cerebellum to premotor cortex. Proprioception - body awareness, where you are, how fast you"re moving, balance. Ganglia are clusters of neurons in the pns.
