Test Questions on Autonomic Nervous System MCAT Questions
Question 1 of 5
The cutaneous innervation of the ear
Correct Answer: D
Rationale: The ear’s cutaneous innervation includes the vagus (auricular branch) for the external auditory canal.
Question 2 of 5
Cerebral palsy affects neurons in which part of the body?
Correct Answer: A
Rationale: Cerebral palsy is a disorder of movement caused by damage to motor neurons in the brain (e.g., cortex, cerebellum) before, during, or shortly after birth. It doesn’t primarily affect the spine or muscles directly.
Question 3 of 5
The surface of the cerebral hemispheres, 2-4 mm thick, consisting of gray matter; arranged in six layers of neuronal cell bodies in most areas.
Correct Answer: D
Rationale: The cerebral cortex is the gray matter surface of the cerebral hemispheres, 2-4 mm thick, with six neuronal layers. Astrocytes are glia, neuropathy is a disorder, and cranial nerves are PNS.
Question 4 of 5
A cluster of neuron cell bodies in the peripheral nervous system.
Correct Answer: B
Rationale: A ganglion is a cluster of neuron cell bodies in the PNS. ACh is a neurotransmitter, synaptic cleft is a gap, and neuropathy is a disorder.
Question 5 of 5
A neuron that propagates nerve impulses toward a synapse.
Correct Answer: B
Rationale: The presynaptic neuron sends nerve impulses toward a synapse, releasing neurotransmitters. Postsynaptic neurons receive signals, enteric plexuses are digestive, and synaptic end bulbs are axon parts.
