Document Summary
Midbrain 2 pigmented nuclei: substantia nigra, appear black because of the high melanin content melanin is required for the synthesis of the neurotransmitter, dopamine. Pons contains 2 respiratory centers: apneustic center, pneumotaxic center, both regulate 2 other respiratory centers in the medulla oblongata. Medulla oblongata most inferior part of the brain continued directly by the spinal cord at the level of the foramen magnum: contains autonomic centers that work in concert with autonomic centers in the hypothalamus. Cerebellum: outer grey matter, )nner white matter arranged like the branches on a tree = (cid:498)arbor vitae(cid:499) Partially divided int o 2 cerebellar hem held together by the vermis (vermis analogous to corpus callosum, which hold the 2 cerebral hem) Each cerebral hem divided into 3 cerebellar lobes: anterior lobe, posterior lobe, flocculonodular lobe cannot be viewed on the surface of the cerebellar hem (analogous to the insula in cerebral hem) Function of the cerebellum is affected by alcohol intoxication.
