PS101 Lecture Notes - Lecture 5: Thalamus, Autonomic Nervous System, Ct Scan
Document Summary
Organization of the nervous system functions (i. e. pulling away when touching something hot) Central nervous system (cns) brain and spinal cord: afferent toward the cns/efferent = away from the cns. Peripheral nervous system nerves that lie outside central nervous system: somatic nervous system voluntary muscles and sensory receptors, autonomic nervous system (ans) controls automatic, involuntary. Hindbrain vital functions medulla, pons and cerebellum. Midbrain sensory functions dopaminergic projections, reticular activating. Forebrain emotion, complex thought thalamus, hypothalamus, limbic.
