Document Summary

Hlsc 2f95: pons, relays sensory information to cerebellum and thalamus, subconscious somatic and visceral motor centres, medulla oblongata, relays sensory information to thalamus and the brain stem, autonomic centers for regulation of visceral function. Organization of the brain: gray matter and white matter organization, the cerebrum consists of: Inner region of gray matter: surrounded by tracts of white matter, gray matter consists of cell bodies, cerebrum and cerebellum white matter is covered by the cortex. Ventricular system of the brain: ventricles are fluid-filled cavities, filled with csf. Hlsc 2f95: lined with ependymal cells, fluid transports nutrients to the cns and transports waste away from the cns, csf made in the choroid plexus, ependymal cells highly permeable capillaries, ventricular system of the brain, lateral. Interventricular foramen: third ventricle, aqueduct of midbrain, fourth ventricle, posterior horns of lateral ventricles. Circulation of cerebrospinal fluid: made in the choroid plexus, about 500ml/day, cir(cid:272)ulati(cid:374)g c f ~(cid:1005)5(cid:1004)(cid:373)l so c f is repla(cid:272)ed e(cid:448)ery 8 hours.
