1. The neuron pictured, below, is best described as:
A. Bipolar
B. Multipolar
C. Unipolar
D. Pseudounipolar
- ANSWER ✔ B. Multipolar
2. True or false: Neurons do not physically touch one another.
- ANSWER ✔ True
3. Describe the synthesis and storage of neurotransmitters. - ANSWER ✔
The neuron cell body manufactures neurotransmitters, which are stored in
secretory vesicles at the end of axon terminals
4. 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
- ANSWER ✔ A. From the central to the peripheral nervous system
5. 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
- ANSWER ✔ B. after the synapse
6. What is the location and function of Satellite cells? - ANSWER ✔
Location: peripheral nervous system (PNS)
Function: Regulation of environment of neuron cell bodies
7. 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? - ANSWER
✔
No, only the peripheral system axons are capable of regeneration. The spinal
cord is the central nervous system
8. 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. -
ANSWER ✔
This is phase 4: afterpolarization (hyperpolarization), the potassium gates
are slow to clse and that results in an undershoot of the potential, the voltage
will drop below -70mV and the return to the restign state beings.
9. At rest, a neuron plasma membrane is:
A. -70 mV
B. +40 mV
, C. Hyperpolarized
D. Depolarized
- ANSWER ✔ A. -70 mV
10.Which of the following is false concerning the sodium-potassium pump?
A. it maintains the resting phase of an axon
B. For every three sodium ions pumped out, two potassium ions are pumped
in
C. it must remain in constant operation to maintain the resting state
D. The overall effect is a negative charge on the outside of the membrane
- ANSWER ✔ D. The overall effect is a negative charge on the outside
of the membrane
11.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
- ANSWER ✔ False, there is no variation in the strength of action
potentials. (It is an all-or-nothing response). There is variation in the
number and frequency of neurons firing
12.Which of the following statements is false concerning the neuromuscular
junction?
A. Sodium ions release from the presynaptic motor neuron
B. Calcium ions release from the sarcoplasmic reticulum to cause muscle
contraction
C. Sodium channels open on the muscle fibers in response to the
neurotransmitter
D. The NMJ is found in the peripheral nervous system
- ANSWER ✔ A. Sodium ions release from the presynaptic motor
neuron
13.What is the purpose of the fossa ovalis in a fetus? - ANSWER ✔
The fossa ovalis marks the place of an opening between the artia which is
present in all the developing fetuses. It allows fetal blood to move directly
from right to left atrium, bypassing the undeveloped lungs. The fossa ovalis
closes during birth so that the lungs can receive oxygen once the baby is
born
, 14.Label the figure below (A-E):
A:
B:
C:
D: (In blue)
E: - ANSWER ✔
A: Superior Vena Cava
B: Right Atrium
C: Tricuspid/Right AV valve
D: Left Ventricle
E. Pulmonary Valve
15.Name the vessel in the figure below: (highlighted in blue, also indicated by
the arrow)
- ANSWER ✔Left Coronary Artery
16.Name the vessel in the figure below: (highlighted in blue, also indicated by
the arrow)
- ANSWER ✔Right marginal artery
17.Name the vessel in the figure below: (highlighted in blue, also indicated by
the arrow)
- ANSWER ✔Circumflex branch
