PHTY201 Lecture Notes - Lecture 4: Cranial Nerve Nucleus, Medial Geniculate Nucleus, Lateral Geniculate Nucleus
Document Summary
4. 1 identify the brainstem and its three main divisions midbrain, pons, medulla oblongata: the brainstem contains areas crucial to the maintenance of life. It enables your brain to integrate sensory information from your eyes and ears with muscle movements: pons: In between the midbrain and the medulla is the pons pronounced round projection on the anterior surface of the brain stem: the pons can be seen to bridge the cerebellar hemispheres when viewed from the front. It helps regular breathing, heart and blood vessel function, digestion, sneezing and swallowing: this is the center for respiration and circulation within the brain, the fourth ventricle lies in the upper part of the medulla. 4. 2 identify some external features of the brainstem and assign functions to these features: the external features contain cranial nerve nuclei which supply the muscles of the neck and back.
