BIO 207 - Human Physiology Test 2 - CSULB Spring 2019 Dr. Gardner CNS (central nervous system) consists of the brain and spinal cord Autonomic Nervous System (ANS) has 2 divisions 1) Sympathetic 2) Parasympathetic Brainpower Read More Neurons do what? send and receive signals Neuroglia (glial cells) cells that support and protect neurons Organs of the nervous system include 1) The brain spinal cord = central nervous system 2) Sense organs (Eyes, ears, etc) 3)Nerves Peripheral Nervous System (PNS) include what 2 divisions? 1) Sensory (afferent) Division 2) Motor (Efferent) Division Functions of the CNS are to PROCESS and COORDINATE: 1. Sensory data: from inside and outside body 2. Motor commands: control activities of peripheral organs (e.g., skeletal muscles) 3. Higher functions of brain: intelligence, memory, learning, emotion Functions of the PNS are: 1) Deliver sensory information to the CNS 2) Carry motor commands to peripheral tissues and systems Dual Innervation Dual Communication Afferent division of PNS Carries sensory information from PNS sensory receptors to CNS (Brain to body) Efferent division of PNS does what? Carries motor commands from CNS to PNS, muscles and glands (Skin to Brain) Receptors of Afferent Division of PNS - Do what?
