Somatic VS Autonomic Nervous system

Somatic (Sensory Input)
from somatic senses and special senses
Autonomic (Sensory Input)
interceptors (sensory receptors located in blood vessels, organs, muscles, and nervous system that monitor conditions of internal organs
Somatic ( Motor Output)
Voluntary from cerebral cortex with help from basal ganglia, cerebellum, brain stem, spinal cord
Autonomic (Motor Output
Involuntary from hypothalamus, limbic system, brain stem, spinal cord, limited control from cerebral cortex
Somatic (Motor Neuron Pathway)
One neuron pathway, somatic motor neurons extending from CNS synapse directly with effector
Autonomic (Motor Neuron Pathway)
Usually Two neuron pathway, ganglionic neurons extending from CNS synapse with post ganglionic neurons in autonomic ganglion, and post ganglionic neurons extending from ganglionic synaptic with visceral effector
Somatic (Neurotransmitters/Hormones)
all somatic motor neurons release ACH
Autonomic (Neurotransmitters/Hormones)
all sympathetic and parasympathetic neurons release ACH
Sympathetic post ganglionic neurons release NE(Sweat glands release)
Parasympathetic neurons release ACH
Chromatin cells of adrenal medulla release epinephrine and norepinephrine
Somatic (Effectors)
skeletal muscle
Autonomic (Effectors)
smooth, cardiac muscle, and glands
Somatic (Responses)
contraction of skeletal muscles
Autonomic (Responses)
contraction/relaxation of smooth muscles
Increase/decrease rate and force of cardiac muscles
Increase/decrease secretions of glands
