Test Questions on Autonomic Nervous System Questions
Question 1 of 5
A fatal disease caused by a virus that reaches the CNS via fast axonal transport.
Correct Answer: B
Rationale: Rabies is a viral disease transmitted via bites, reaching the CNS through axonal transport, causing neurological symptoms and death. Effectors are targets, myelin sheath is insulation, and axosomatic is a synapse.
Question 2 of 5
Three main components of neurons are
Correct Answer: D
Rationale: Neurons consist of dendrites (receive signals), cell body (soma, with nucleus), and axon (transmits signals). Nucleus is part of the cell body, neurofibrils are internal, and nodes are axon features.
Question 3 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 4 of 5
Which of the following controls the 'fight-or-flight' response?
Correct Answer: D
Rationale: The autonomic nervous system (specifically sympathetic division) controls the fight-or-flight response, increasing heart rate and alertness. CNS integrates, spinal cord relays, and cranial nerves serve head.
Question 5 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.
