Document Summary
Sylvian fissure- the division that separated the temporal lobe from the frontal and parietal lobes. Neuroanatomy- the study of the nervous system. Occurs at two levels: gross neuroanatomy- which focuses on general structures and connections visible to the naked eye, fine neuroantomy ( microscopic neuroantomy)- describes the organization of neurons and their connections and sub cellular structure. Dura mater-consists of dense layers of colagenous fibers hard mother . Gryi- the protruded rounded surfaces seen in the cortex of the cns. Sulci- the smaller invaginations ( creases) in the cns and fissures the larger invaginations. Gray matter- forms a continuous cortical sheath enshrouding a seemingly homogenous mass of white matter: contains cell bodies of neurons and glial cells. White matter- appears white due to the fatter tissue called my lien sheaths surrounding the axons. Microanatomy and histology: cell staining and tract tracing.
