PSYA01H3 Chapter Notes - Chapter 3.3: Sympathetic Nervous System, Direct Energy, Brainstem
Document Summary
Joordens: divisions of the nervous system, central nervous system (cns): consists of the brain and spinal cord. Limitless capacity to store information: personality, preferences, memories, conscious awareness. Spinal cord: receives information from brain and stimulates nerves that extend out into the body, producing movement, receives information from sensory nerves and transmits it back to brain. Critical for survival: peripheral nervous system (pns): transmits signals between the brain and the rest of the body and is divided into two subcomponents: Somatic nervous system: consists of nerves that control skeletal muscles, which are responsible for voluntary and reflexive movement; also consists of nerves that receive sensory input from body: any voluntary behaviour makes use of this system. Balance, coordination, and timing of movements; attention and emotion.
