ANP 1106 - SENSORY SYSTEM UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS

Question:
1. What does CNS relies on to provide input from sensory
recptors in the body?

Answer:
PNS

Question:
2. Sensation

Answer:
awareness of changes in the internal and external environment

Question:
3. Perception

Answer:
conscious interpretation of those stimuli cerebal cortex interpretation of sensory
input

Question:
4. Receptor level

Answer:
Sensory receptors detect specific stimuli (e.g., photoreceptors in eyes,
mechanoreceptors in skin)

Question:
5. Where does perception occurs?

Answer:
cerebral cortex

Question:
6. Circuit level

Answer:
Ascending pathways transmit impulses from sensory receptors to the CNS (spinal
cord → brainstem → thalamus → cortex)

, Question:
7. Perception level

Answer:
Cerebral cortex interprets these impulses as meaningful sensations

Question:
8. Structure of Nonencapsulated nerve endings

Answer:
Free nerve endings of sensory neurons - Bare dendrites, no connective tissue
capsule around them




Question:
9. Function of Nonencapsulated nerve endings

Answer:
Mainly detect pain (nociceptors), temperature (thermoreceptors), and light
touch

Question:
10. Where are nonencapsulated nerve endings found?

Answer:
Most body tissues: most dense in connective tissues and epithelia

Question:
11. Structure of Encapsulated Nerve Endings

Answer:
Dendrites enclosed in connective tissue capsule. Capsule enhances sensitivity to
pressure, vibration, or stretch.

Question:
12. Function of Encapsulated Nerve Endings

Answer:
Detect touch, pressure, vibration, and proprioception (body position)
