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.
<h3>What are Skeletal muscles?</h3>
Skeletal muscles may be defined as the muscles that fasten to your bones and authorize you to achieve a broad range of activities and operations.
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. It is a prolonged, delicate tubelike network liable for holding incoming and outgoing messages through the brain to the rest body.
Therefore, it is well described above.
