Question

The following is the scheme showing the path of the reflex arc. Identify the different labelings A, B, C, D, E and F in the reflex arc

• A. A - Stimulus, B - Effector, C - Motor nerve, D - Sensory nerve, E - Receptor, F - Response
• B. A - Stimulus, B - Receptor, C - Motor nerve, D - Sensory nerve, E - Effector, F - Response
• C. A - Stimulus, B - Effector, C - Sensory nerve, D - Motor nerve , E - Receptor, F - Response
• D. A - Stimulus, B - Receptor, C - Sensory nerve, D - Motor nerve , E - Effector, F - Response

Answer 1

The correct option is D A - Stimulus, B - Receptor, C - Sensory nerve, D - Motor nerve , E - Effector, F - Response

This image represents the path of the reflex arc. It is similar to this diagram.

In the figure given in the question,
The stimulus (A) is sensed by the receptor (B). The receptor then sends nerve impulses to the spinal cord through the sensory neuron (C). The nerve impulse is then transferred to the motor neuron (D) through the interneuron. The motor neuron then carries the nerve impulse for the response to the effector (E), which then effects the response (F).
