BIOL 2443 Study Guide - Final Guide: Cranial Nerves, Diencephalon, Brainstem
Document Summary
Cerebrum, cerebellum, diencephalon, brainstem: cerebrum, cerebellum, diencephalon, brainstem. Divided into left and right cerebral hemispheres. Surface layer of gray matter = cerebral cortex. Hypothalamus (base of diencephalon) is involved with. Diencephalon: major endocrine gland, connected to hypothalamus via infundibulum (stalk) Relays information between spinal cord and cerebrum or cerebellum. Nuclei for somatic and visceral motor control. 4: embryonic development of the brain, determines organization of brain structures, neural tube, develops into cns, rostral portion enlarges to form three primary brain vesicles, prosencephalon ( forebrain , mesencephalon ( midbrain , rhombencephalon ( hindbrain ) Joins central canal of spinal cord: connects with third ventricle with fourth ventricle, via narrow canal in midbrain (cerebral aqueduct) Physical protection of the brain: bones of the cranium, cranial meninges, cerebrospinal fluid. Biochemical isolation: blood brain barrier, physical protection of the brain: cranial meninges continuous with spinal meninges. Inner fibrous layer (meningeal cranial dura: outer fibrous layer (periosteal cranial dura, fused to periosteum.
