BIO 181 CAPCO ASU EXAM 3 FINAL 2026
PRACTICE QUESTIONS AND ANSWERS TOP
REVIEW A+
◉ T/F Fast neurons as described in lecture are fast because they are
surrounded by a type of glial cell that results in a myelin coating.
Answer: False
◉ T/F The axon from a pre-synaptic cell contacts the axon of
another neuron. Answer: False
◉ List the 4 types of glial cells and list a phrase to describe their
function. Answer: - Microglia: Are part of the cellular immune
system to protect the brain since the humoral immune system
usually cannot cross the BB barrier.
- Astrocytes: Contribute to the blood brain barrier
- Schwann Cells: myelinates axons of the neurons in the PNS
- Oligodendrocytes: Myelinates axons of the neurons of the CNS
◉ The central nervous system (CNS) contains: Answer: Brain and
Spinal Cord (There is no correct answer).
, ◉ T/F Fast neurons as described in lecture require cytoplasmic
signal transduction to open an ion channel. Answer: False
◉ T/F Acetylcholine esterase breaks acetylcholine into muscarinic
acid Answer: False
◉ T/F The membrane potential (resting potential) is largely set by
the Na-K- ATPase pump. Answer: True
◉ T/F The receptors in post-synaptic cells are the basis on which
the synapse can be defined as inhibitory or excitatory. Answer: False
◉ T/F
The axon hillock in the pre-synaptic neuron fires based on temporal
and spatial summation of inputs. Answer: True
◉ T/F
Voltage-gated ion channels open when a protein binds to the
receptor. Answer: False
◉ The neural tissues are: Answer: Spinal cord, sensory neurons, and
brain
