Document Summary
Anterior: towards front or head in 4 legged verts. Posterior: towards back or tail in 4 legged verts. Dorsal: towards surface of back, top of head. Ventral: towards surface of chest, bottom of head. Medial: towards central line of body. Lateral: further from midline of body. Planes of view: horizontal - parallel to ground, frontal - parallel to face, sagittal - pro le/side. Spinal cord: easiest to study with cross sections, grey matter - butter y shape, nerve cell bodies, white matter - myelinated tracts, dorsal horns, ventral horns - thicker than dorsal, involved in motor movements. Myelencephalon: medulla, oldest part of brain, sleep, attention, muscle tone, respiration, cardiac function. Metencephalon: cerebellum and pons, c - ne motor movements, p - reticular formation, ascending and descending neural tracts, midbrain. Telencephalon - cerebral cortex, most complex functions: longitudinal ssure - splits in half, central ssure - splits in front and back (frontal from parietal)
