A nurse asks a patient to stand with the eyes closed. The patient loses balance because information about limb position is impaired. Which sensory system is most directly involved?
Correct answer: A. Proprioceptive system
- A. Proprioceptive system
- B. Auditory system
- C. Olfactory system
- D. Gustatory system
Explanation
Proprioception provides information about joint position, muscle stretch, and body movement. It helps maintain posture, especially when visual information is removed, whereas the other systems detect sound, smell, and taste.

About Nervous System and Special Senses
The nervous system covers neurons, neuroglia, nerve impulses, synapses, reflex arcs, and the organization of the central and peripheral nervous systems. It also explains the autonomic divisions and the receptors and pathways for vision, hearing, balance, taste and smell, distinguishing sensory reception from conscious perception.
