Document Summary

Organization of the brain ch 15a organization of the brain regions. The brain is composed of 4 major regions: cerebrum, diencephalon, brainstem, cerebellum gyri & sulci. Outer surface of brain"s cerebrum is wrinkled. Sulci: in btwn gyri - grooves or crevices neural tissue organization gray matter. Motor neuron & interneuron cell bodies, dendrites, unmyelinated axons. Cerebral cortex, covers surface of most of adult brain white matter. Deep to the gray matter of the cortex support & protection of the brain overview. Brain is protected by many structures: bony cranium, protective connective tissue (meninges, cerebrospinal fluid, blood-brain barrier bony cranium. Circulate cerebral spinal fluid meninges: structures & associated spaces. Epidural space: btwn cranial & dura mater: dura mater: 2 sublayers - tough/durable. Subdural space: deep to dura mater: arachnoid mater: spider web like extensions supyersici% dllp. Subarachnoid space: deep to arachnoid mater: pia mater: thin, delicate later - adhered to surface of cerebrum brain ventricles.
