Overview of Nervous System Divisions - Matching Flashcards
Nerves of brain & spinal cord
Central Nervous System
Nerves outside of brain & spinal cord
Peripheral Nervous System
Provides sensory information for body
Afferent/Sensory Division
Controls muscle and organs
Efferent/Motor Division
Actions—APs in these nerves control skeletal muscle contraction
Somatic Nervous System
Actions—APs in these nerves control smooth muscle, cardiac muscle, and the activities of organs and glands
Autonomic Nervous System
Type of Control—Voluntary, conscious
Somatic Nervous System
Type of Control—Involuntary, unconscious
Autonomic Nervous System
Nerve Composition—One neuron from CNS to muscle
Somatic Nervous System
Nerve Composition—Two neurons joined end to end;
The 1st (PREGANGLIONIC) neuron synapses with the 2nd (POSTGANGLIONIC) neuron at GANGLIA
Autonomic Nervous System
Effects—Always excitatory—Causes movement, posture, balance
Somatic Nervous System
Effects—Either excitatory or inhibitory
Autonomic Nervous System
Neurotransmitter Used—Acetylcholine (ACh)
Somatic Nervous System
In skeletal muscle, the Cholinergic Receptor (ACh receptor) is called a _ _ _ _.
Nicotinic Receptor
