Test Questions on Autonomic Nervous System Questions
Question 1 of 5
A photoreceptor in the eye could be classified into which of the following categories?
Correct Answer: C
Rationale: Photoreceptors (rods, cones) in the eye are sensory receptors, detecting light. Smooth muscle is an effector, somatic nerve controls voluntary muscles, and ganglion is a cell body cluster.
Question 2 of 5
Hirschsprung's disease is a disorder in which the large intestine has no nerves and cannot function as it should. This is a problem with which of the following parts of the nervous system?
Correct Answer: D
Rationale: Hirschsprung’s disease involves absent enteric nervous system ganglia in the large intestine, impairing motility. Somatic controls voluntary muscles, sympathetic is ANS, and CNS is brain/spinal cord.
Question 3 of 5
The cerebellum and cerebrum are covered by
Correct Answer: B
Rationale: The cerebellum and cerebrum are covered by gray matter (cortex), containing neuronal cell bodies. White matter is internal, neuroglia are supportive cells, and ganglia are PNS.
Question 4 of 5
The nerve that accompanies the submental artery is the
Correct Answer: B
Rationale: The mylohyoid nerve (a branch of the inferior alveolar nerve from CN V3) accompanies the submental artery, supplying the mylohyoid muscle and anterior digastric. The cervical branch of the facial nerve (CN VII) supplies platysma, the transverse cervical nerve (C2-C3) is cutaneous, and the great auricular nerve (C2-C3) innervates the ear.
Question 5 of 5
A bundle of axons in the peripheral nervous system is a:
Correct Answer: B
Rationale: A nerve is a bundle of axons in the PNS (e.g., sciatic nerve). Tracts are CNS, cell bodies are soma, and neuroglia support.
