Question

Which of the following lists the parts of a reflex arc in the correct sequence?a. receptor, sensory neuron, motor neuron, interneuron, effectorb. effector, receptor, sensory neuron, motor neuron, interneuronc. effector, sensory neuron, receptor, interneuron, motor neurond. receptor, sensory neuron, interneuron,motor neuron, effector

Answer 1

Answer:

d. receptor, sensory neuron, interneuron, motor neuron, effector

Explanation:

Receptor is the first component of the reflex arc with the function to receive signal (it detects the change in environment, external or internal).

Sensory neuron is responsible for the transport of signal from the receptor to the interneuron which is then connected with the motor neuron.Motor neuron further sends the signal to the effector which produces the response (e.g. muscle contraction).
