Correct Answer: Option E
Explanation:
The correct answer is E: 3-4-1-5-2.
Explanation:
Reflex actions are involuntary and automatic responses to stimuli, which follow a specific pathway known as the reflex arc. Here's how the sequence works:
1. 3. Skin: The stimulus is received by the skin, such as heat or pain.
2. 4. Sensory nerve: The sensory nerve transmits the signal from the skin to the central nervous system.
3. 1. Central nervous system: The signal is processed in the spinal cord (in some reflexes) or brain, which is part of the central nervous system (CNS).
4. 5. Motor nerve: The motor nerve carries the response signal from the CNS to the muscles.
5. 2. Muscles: The muscles respond to the signal by contracting or relaxing to produce movement.
Thus, the correct sequence for the reflex action is 3 (Skin) → 4 (Sensory nerve) → 1 (Central nervous system) → 5 (Motor nerve) → 2 (Muscles).
This is why E: 3-4-1-5-2 is the correct answer.
