BIOD 152 - Module 1 Exam Questions and Correct Answers Latest Update 2024 Already Passed
This is a collection of cell bodies found in the peripheral nervous system. - Answers Ganglia
This part of the autonomic system increases digestion. - Answers Parasympathetic
The ventral root of a nerve contains what type of neurons? - Answers Motor
This part of a neuron conducts nerve impulses towards the cell body. - Answers Dendrite
A neuron going to the bicep of the forearm is part of the: - Answers Peripheral Nervous System
Somatic Nervous System
The neuron pictured, below, is best described as: - Answers Multipolar
True or false: Neurons come into direct physical contact with one another. - Answers False
Describe the function and release of neurotransmitters. - Answers Neurotransmitters are chemicals
stored inside secretory vesicles/ axon terminal vesicles at the end of the axon terminal.
When neurotransmitters are released by the axon terminal vesicles they carry the transmission of the
nerve impulse from 1 neuron to another.
An efferent neuron carries information: - Answers From the central to the peripheral nervous system
A postsynaptic neuron would be found: - Answers after the synapse
What is the location and function of Satellite cells? - Answers Location - Peripheral Nervous System
Function - Regulation of environment of neuron cell bodies
A patient's spinal cord was severed in a car accident. Would the patient be expected to regrow axons in
their spinal cord? Why or why not? - Answers No, only the Peripheral Nervous System axons regenerate.
Name and describe what is occurring in the neuron cell membrane in section 4 of the diagram. Include
the charge of the membrane during this phase. - Answers Afterpolarization - K gates close slowly and the
potential is undershot
The charge drops below -70mV and then returns to -70mV once at resting again
At rest, a neuron plasma membrane is: - Answers -70mV / Polarized
Which of the following is true concerning the sodium-potassium pump? - Answers It must remain in
constant operation to maintain the resting state.
True or false: A sensory neuron is signaling the body of extreme pain. This means that the strength of
the action potential is greater than usual. Explain your reasoning. - Answers False - action potentials are
