Question

If you pick up a hot plate _____________ receptors in your ___________ detect this change

• A. motor, skin
• B. sensory, muscle
• C. sensory, skin
• D. intermediate, muscle

Answer 1

The correct option is C sensory, skin

The nerve pathway followed by a reflex action is called a reflex arc. For example, a simple reflex arc happens if we accidentally touch something hot.

1. Sensory rceceptor in the skin detects a stimulus (the change in temperature).
2. Sensory neurone sends impulses to relay neurone.
3. Motor neurone sends impulses to effector.
4. Effector produces a response (muscle contracts to move hand away).
