Somatic Motor vs Visceral Motor

effector of somatic motor
skeletal muscle
effector of visceral motor
smooth and cardiac muscle, glands, fats
where are peripheral autonomic motor neurons distributed w in nerve of spinal cord
specific regions and segments
where are peripheral somatic motor neurons distributed w in nerve of spinal cord
all 31 segements
peripheral autonomic motor neuron cell bodies located
lateral horn
peripheral somatic motor neuron cell bodies located
ventral horn
how many peripheral neurons involved in autonomic motor
2
how many peripheral neurons involved in somatic motor
1
where is there a synapse for autonomic motor neurons but not for somatic motor
between cns and target cell
where is the synapse between the two peripheral autonomic motor neurons
ganglia
what can autonomic motor neurons be at effector
excitatory or inhibitory
what can somatic motor neurons be at effector
excitatory
what does the 2nd peripheral autonomic motor neuron form at effector
varicosities that cover organ cells
what does the peripheral somatic motor neuron form at effector
motor end plate at neuromuscular junction
what neurotransmitters to autonomic motor release
ACH or norepinephrine
what neurotransmiters do somatic motor release
ach
where does the first autonomic motor neuron coming from the lateral horn go to
autonomic ganglia
what are the two things a neuron can do once it is in autonomic ganglia
synapse w another neuron and travel out spinal nerve, travel up or down to another neuron where it will pass out
why do autonomic motor neurons have to enter the autonomic ganglia
to synapse w cell body of another neuron
what is contained w in the chain ganglia
axons and cell bodies of autonomic fibers
where do both somatic and visceral motor neurons first travel out to from the spinal cord
ventral root
what is the route the somatic motor neuron has from spinal cord to the effector
single neuron comes out containing a bundle of neurons, their axons all travel to the effector
what is the route the visceral motor neuron has from spinal cord to the effector
first neuron comes out and enters ganglion, first neuron synapses w second neuron in ganglion, second neuron travels to the effector
what is the first neuron of autonomic motor
preganglionic
what is the second neuron of autonomic motor
postganglionic
which autonomic motor fiber innervates the effector organ
postganglionic
how does the somatic motor neuron release its neurotransmitter at effector
motor end plate is formed at neuromuscular junction where neuron forms connection w muscle and releases neurotransmitter
how does the visceral motor neuron release its neurotransmitter at effector
neuron forms series of bulb like varicosities that cover the organ w neurotransmitter at the actual effector
what is within all 31 segments of spinal cord
somatic motor and somatic sensory neuron
