January 27, 2009 o Common terms used in Neuroanatomy (anatomy) o White matter: compromised primarily of Myelin (lipid/fat) o Grey matter: neuropil (axons and dendrites), glial cells (astroglia and oligodendrocytes) and capillaries. Grey matter contains neural cell bodies, in contrast to white matter, which is composed mainly of myelinated axon tracts. [1] The color difference arises mainly from the whiteness of myelin. In living tissue, grey matter actually has a grey-brown color which comes from capillary blood vessels and neuronal cell bodies. o Hormones are secreted by glands where they travel and reach target tissue by means of the circulatory system. They regulate physiological function. Some of them also reach a particular chunk of tissue: the CNS Influence behavior by interacting with brain o Correlation: o Pituitary gland: master gland Anterior Posterior o Hypothalamus Responsible for hunger Two nuclei important for feeding Hunger center: lateral
