The nervous system and the muscle system respond to stimuli to produce motion. The skeletal movements of muscles are mostly voluntary.
Involuntary movements occur in these muscles when the nerve impulse passes from a sensory neuron to a motor neuron via an interneuron in the spinal cord.

Skeletal muscles control the direct movement of a person's will and are hence referred to as voluntary movement. While the spinal cord is associated with both movements directly or indirectly.

Therefore, it is well described above.

<span>Dr. Stott is researching epigenetics. Epigenetics is the study of changes that occur in gene expression with no changes in the actual gene sequences. Environmental factors can influence gene expression without changing the DNA sequence, making this the study of epigenetics.</span>
Answer:
Explanation:
A cervical collar was used to avoid movement and prevent further damage incase he has a fracture.
light is focused in one eye,the pupil will constrict as a respond to the light flashed. It is repeated Again and observed.
