Q1 QUESTION 1 OF 68
this is a collection of cell bodies found in the peripheral nervous system
CORRECT ANSWER
ganglia
RATIONALE
Ganglia are clusters of neuron cell bodies located outside the central nervous system, functioning as relay points in the transmission of
sensory and motor information. This anatomical feature is crucial for the organization and processing of peripheral nervous system
signals.
Q2 QUESTION 2 OF 68
this part of a neuron conducts nerve impulses towards the cell body
CORRECT ANSWER
dendrites
RATIONALE
Dendrites are specialized extensions of neurons that receive and conduct electrical impulses toward the cell body, facilitating synaptic
transmission and communication within the nervous system. This structural function is crucial for integrating signals from other neurons.
Q3 QUESTION 3 OF 68

, the neuron pictured below is best described as
CORRECT ANSWER
bipolar
RATIONALE
Bipolar neurons are characterized by two distinct processes—one axon and one dendrite—emerging from opposite ends of the cell body,
facilitating sensory signal transmission. This structural arrangement is commonly found in sensory pathways, such as those for vision and
olfaction.
Q4 QUESTION 4 OF 68
T/F: neurons do not physically touch one another
CORRECT ANSWER
true
RATIONALE
Neurons communicate via synapses, where neurotransmitters cross the synaptic cleft, allowing for signal transmission without direct
physical contact. This principle underscores the importance of chemical signaling in neural communication and the functional
architecture of the nervous system.
