In order to stimulate an effector in a toe, which pathway does a nerve impulse follow after it is initiated at a receptor?

a. sensory neuron -> interneuron -> motor neuron
b. motor neuron -> interneuron -> sensory neuron
c. interneuron -> sensory neuron -> motor neuron
d. none of these

sensory nuerone to internuerone to motor neurones

Explanation:

The sensory nuerone usually receive inputs from the receptors cells in the skin,organs,and other parts of the body.

These receptors send signals as action potential to the spinal cord to the brain.(CNS).

Synapse take place at the synaptic junctions, in the spinal cord with the internuerone.

The latter transmit the action potential to the motor neuron which synapse with the internuerone and transmita signal to the neuromuscular junction where it synapse with the muscels at the toe.

The action potentials causes influx of calcium ions and the relase of acetylcholine neurotransmitters for action potential to reach the toe muscles (effector)for contraction

it would be c. xylem.
