Central Nervous System (CNS) - ANSWER brain and spinal cord Peripheral Nervous System (PNS) - ANSWER the sensory and motor neurons that connect the central nervous system (CNS) to the rest of the body. What are the three main functions of the nervous system - ANSWER Sensory - gather information (stimuli) = afferent division (PNS) Integrate - process information = CNS Motor - action in response to stimuli = efferent division

Central Nervous System (CNS) - brain and spinal cord Peripheral Nervous System (PNS) - the sensory and motor neurons that connect the central nervous system (CNS) to the rest of the body. What are the three main functions of the nervous system - Sensory - gather information (stimuli) = afferent division (PNS) Integrate - process information = CNS Motor - action in response to stimuli = efferent division (PNS) What does Amitotic mean and what part of the nervous system does it impact? ...

Resting membrane potential is the product of which channels? K+ leak channels Na+/K+ ATPase What makes neuronal messaging across a membrane possible? A potential because of the charge separation across the membrane At RMP what side are the + and - charges Outside + Inside - How is the RMP maintained? (2 parts) 1. K+ diffusion is in dynamic equilibrium 2. Na/K pump sends out 3Na for every 2K it brings in Channels used by local potentials? Gated K+ channels Action potentials use which channel...
