BIOD 152 Module 1
Review
1.This is a collection of cell bodies found in the peripheral nervous system.-
: Ganglia
2.This part of the autonomic system increases digestion.: parasympathetic
3.The ventral root of a nerve contains what type of neurons?: Motor
4.This part of a neuron conducts nerve impulses towards the cell body.:
Den- drites
5.A neuron going to the bicep of the forearm is part of the:: Peripheral
nervous system and somatic system
6.The neuron pictured, below, is best describes as:: multipolar
7.True or false: Neurons come into direct physical contact with one another.
: False: neurons do not physically touch. They are separated by synapses
8.Describe the function and release of neurotransmitters.:
Neurotransmitters are chemicals stored inside
secretory vesicles (axon terminal vesicles) at
the end of the axon terminals.
When neurotransmitters are released by the
axon terminal vesicles, they carry the
transmission of the nerve impulse from one
neuron to another.
9.An efferent neuron carries information:: From the central to the
peripheral nervous system
10.A postsynaptic neuron would be found:: After the synapse
11.What is the location and function of Satellite cells?: Location:
Peripheral nervous system (PNS)
Function: Regulation of environment of neuron cell bodies
12.A patient's spinal cord was served in a car accident. Would the patient
be expected to regrow axons in their spinal cord? Why or why not?: No
because only peripheral systems axons can regenerate
13.Name and describe what is occurring in the neuron cell membrane
in section 4 of the diagram. Include the charge of the membraneuring
d this
phase.: Afterpolarization (hyper polarization) potassium gates w to close
are slo there is an undershoot of the potential and
The charge drops below -70mV and then returns to -70mV once
at r again esting state
