Which of the following is the correct simple spinal reflex arc? a. receptor, afferent neuron, integration center, efferent neuron, effector b. receptor, efferent neuron, integration center, afferent neuron, effector c. effector, efferent neuron, integration center, afferent neuron, receptor d. effector, afferent neuron, integration center, efferent neuron, receptor

The correct answer is A.

Explanation:

Spinal Reflex Arc is a term describing the neural pathway a signal follows when there is a triggered reflex. The first step is the arrival of the signal that causes the arc to start, which can be an external stimuli. Then this signal activates the afferent neuron which is responsible for carrying the stimuli signal to the central nervous system. The signal arrives at the part of the system that processes and decides what action should be taken next, which is the integration center. From here after it is decided, the signal arrives at the efferent neuron, which is a motor neuron which sends the signal from the nervous system down to the muscles. Lastly the response arrives at the effector and the cycle gets completed with an action towards the stimuli.
