BIO 181 (Capco ASU) Exam 3 (Final
Exam) 2025/2026 Exam Questions and
Correct Answers | New Update
T/F Excitatory synapses cause hyperpolarization of post-synaptic cells. - 🧠
ANSWER ✔✔False
The resting potential of neurons is: - 🧠 ANSWER ✔✔-60 mv (The answer is
not on this list.)
T/F The autonomic nervous system contains the sympathetic and the
parasympathetic nervous system. - 🧠 ANSWER ✔✔True
In the motor end plate, the event that is the immediate trigger for exocytosis
is: - 🧠 ANSWER ✔✔Calcium Ions
Draw an action potential in the axon of a neuron and indicate which ions
flow into the neuron and out of the neuron as the action potential passes at
,the point where the electrodes are in the cell. Be sure to assign on the Y-
axis the mV of each of these areas. This should be as described in my
lectures. - 🧠 ANSWER ✔✔
The action potential is: - 🧠 ANSWER ✔✔A result of the movement of ions.
T/F The cell body refers to the part of the neurons that begin at the
dendrites and extend to the axon terminal. - 🧠 ANSWER ✔✔False
T/F When the presynaptic cell contacts a muscle cell, the synapse area is
called a motor end plate. - 🧠 ANSWER ✔✔True
The post-synaptic cell can be: - 🧠 ANSWER ✔✔In glands, muscle cells,
neurons
T/F Excitatory synapses cause depolarization of the post-synaptic cell. - 🧠
ANSWER ✔✔True
T/F Only pre-synaptic neurons are coated with myelin. - 🧠 ANSWER
✔✔False
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
