ANP 330 Lecture Notes - Lecture 32: Caudate Nucleus, Claustrum, Pineal Gland
Document Summary
Masses of gray matter deep in cerebral hemisphere. Act as relay station for motor impulses starting in cerebral cortex and passing to brain stem & spinal cord. Diencephalon: epithalamus, posterior pituitary gland, thalamus, hypothalamus. Two major bodies: divide by 3rd ventricle, connected by a inter thalamic adhesion. Part of limbic system (emotion, memory, learning, conscious awareness of emotion) Connect basal nuclei and cerebral cortex (to each other & to other parts of cns) Sends sensory info to proper location within cerebrum. Hypothalamus functions: subconscious control of skeletal muscles, coordinates autonomic nervous system, connects endocrine and nervous system, produces hormones, produces behavioral drives, regulates body temp, controls sleep patterns. Connects brain stem & spinal cord with higher areas. Contain cerebral aqueduct that connects 3rd & 4th ventricles. 4 parts: cerebral peduncles, red nucleus, substantia nigra, corpora quadrigemina. Consists of connecting fibers: motor fibersconnecting cortex to spinal cord, sensory fibers that synapse with the thalamus.
