Cell bodies of the peripheral nervous system are located in
ganglia
Schwann Cell
The motor division
The sensory division
Nerves
The sensory (afferent) division of the peripheral nervous system
Transmit action potential to sensory organs
Transmit action potential toward the CNS
Stimulates glands to release hormones
Stimulates muscle contractions
does not involve sensory receptors
The motor (efferent) division of the peripheral nervous system
is a division of the CNS
regulates the digestion of food
transmit impulse from the CNS to skeletal muscle
as nerve cell bodies located in ganglia near the spinals cord and brain
Digestion of food is regulated by the
sensory division
parasympathetic division of the ANS
somatic nervous system
none of the above
Nissl bodies are
part of a dendrite
also called gemmules
lipid droplets
ribosomes associated with rough endoplasmic reticulum
Dendrites
Are the input part of the neuron
conduct action potential away from the cell body
are generally long and unbranched
form synapse with the microglia
contain the trigger zone
Axons
contain the nucleus
are numerous extensions from each neurons
do not have a trigger zone
have a distal portion that branches to form the axonic terminals
do not have a resting membrane potential
Mielinated axons contain
Schwann cells
foot processes
Nissl bodies
the soma
the rough endoplasmic reticulum
synaptic vesicles that contain neurotransmitter are present in the
dendrites
cell body
axolemma
presynaptic terminals or axonic terminals
A neuron that carries action potentials from one neuron to another is called a(n)---
motor neuron
sensory neuron

calcium ions
chloride
proteins
During the absolute refractory period, the cell
generates many local potentials

Dermatomal maps are important clinically because they
can be used to check for motor function
locate the position of cranial nerves
can be used to help locate nerve damage

Arrange the events of the synaptic transmission in correct sequence

2.neurotransmitter binds with receptor on the postsynaptic cell.
3.neurotransmitter diffuses across the synaptic cleft
4. ligand fated sodium ions channels open on postsynaptic cell
5.action potential causes release of neurotransmitters
