Which components of a general reflex arc are listed in the order information typically flows through them following a stimulus?

A. Effector, afferent pathway, integrating center, efferent pathway, receptor
B. Effector, efferent pathway, integrating center, afferent pathway, receptor
C. Integrating center, receptor, afferent pathway, efferent pathway, effector
D. Receptor, efferent pathway, integrating center, afferent pathway, effector
E. Receptor, afferent pathway, integrating center, efferent pathway, effector

Answer :

Final answer:

The correct order following a stimulus in a reflex arc is receptor, afferent pathway, integrating center, efferent pathway, effector, corresponding to how the body detects and responds to stimuli, hence correct option is E.

Explanation:

This is represented as: Stimulus → Receptor → Afferent Pathway → Integrating Center → Efferent Pathway → Effector. In this sequence, the receptor detects the stimulus and sends a signal along the afferent pathway to the integrating center, typically the spinal cord or brain.

The integrating center processes the input and sends a response via the efferent pathway to the effector, which carries out the response, such as a muscle contraction.
