1. Collection of cell bodies in the PNS.
Answer: Ganglia
Explanation: Ganglia are clusters of neuronal cell bodies located in the peripheral nervous
system (PNS).
2. This part of the autonomic nervous system increases digestion.
Answer: Parasympathetic nervous system
Explanation: The parasympathetic division is responsible for "rest and digest" functions,
including stimulating digestion.
3. The ventral root of a spinal nerve contains what type of neurons?
Answer: Motor (efferent) neurons
Explanation: The ventral root carries motor signals from the spinal cord to effector organs like
muscles and glands.
4. The neuron part that conducts a nerve impulse away from the cell body.
Answer: Axon
Explanation: The axon is a long, slender projection that transmits electrical impulses away from
the neuronal cell body.
5. An interneuron inside the spinal cord is part of the:
Answer: Central nervous system (CNS)
Explanation: Interneurons reside entirely within the brain or spinal cord, which are components
of the CNS.
6. Describe the synthesis and storage of neurotransmitters.
Answer: Neurotransmitters are synthesized in the cell body, transported down the axon, and
stored in synaptic vesicles within the axon terminal.
Explanation: This process ensures neurotransmitters are ready for release upon the arrival of an
action potential.
7. An efferent neuron carries information:
Answer: From the central nervous system to the peripheral nervous system
, Explanation: Efferent (motor) neurons transmit commands from the CNS to muscles, glands,
and organs.
8. Location and function of astrocytes.
Answer: Location: CNS. Function: Form the blood-brain barrier and regulate the chemical
environment for neurons.
Explanation: Astrocytes are a type of glial cell crucial for maintaining CNS homeostasis.
9. The phases of an action potential are:
Answer: Depolarization, repolarization, and after-hyperpolarization (hyperpolarization).
Explanation: These phases represent the rapid change in membrane potential that constitutes a
nerve impulse.
10. At rest, a neuron's plasma membrane is:
Answer: Polarized
Explanation: The resting membrane potential is polarized, typically around -70mV, due to the
uneven distribution of ions.
11. True or False: The sodium-potassium pump must remain in constant operation to maintain
the resting state.
Answer: True
Explanation: The Na+/K+ ATPase pump actively maintains the concentration gradients
essential for the resting potential.
12. Where does the neuromuscular junction (NMJ) terminate?
Answer: On the sarcolemma (cell membrane) of a skeletal muscle fiber
Explanation: The NMJ is the synapse between a motor neuron and a muscle fiber.
13. How is a message sent from one neuron to another?
Answer: Via electrochemical signaling: an electrical action potential leads to the chemical
release of neurotransmitters across a synapse.
Explanation: This process allows for communication between neurons and their targets.
