Which statement describes exteroceptors?

• A. Located near external environment stimuli, such as tactile receptors in skin.
• B. Located only within internal organs.
• C. Detect chemical changes in blood.
• D. Detect motor commands.

Answer: (A)

Exteroceptors are sensory receptors that sense stimuli from outside the body. They are located at or near the body’s surface where external cues are encountered, such as tactile receptors in the skin that respond to touch, pressure, or temperature. This external orientation lets you detect changes in the surrounding environment directly. In contrast, other receptors monitor internal conditions (interoceptors) or sense limb position and movement (proprioceptors), and motor commands are not detected by receptors at all.
