BIOD 152 Exam 1 Questions with 100%
Correct Answers
This is a collection of cell bodies found in the peripheral nervous system.
Ganglia
This part of the autonomic system increases digestion
Parasympathetic
The ventral root of a nerve contains what type of neurons?
Motor (Efferent)
This part of a neuron conducts nerve impulses towards the cell body.
Dendrites
A neuron going to the bicep of the forearm is part of the:
A. Central nervous system
B. Peripheral nervous system
C. Autonomic system
D. Somatic system
E. A&C
F. B&D
F
The neuron pictured, below, is best described as: (picture 2)
Bipolar
Multipolar
, Unipolar
Pseudounipolar
Multipolar
True or false: Neurons come into direct physical contact with one another.
False: Neurons do not physically touch. They are separated by synapses.
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.
An efferent neuron carries information:
A. From the central to the peripheral nervous system
B. From the peripheral to the central nervous system
C. Within the central nervous system
D. Within the peripheral nervous system
A
A postsynaptic neuron would be found:
A. Before the synapse
B. After the synapse
C. Inside the synapse
D. Only in the central nervous system
B
What is the location and function of Satellite cells?
