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.

Chromosomes particularly eukaryotic chromosomes are made up of nucleic acids in particular DNA (deoxyribonucleic acid) and some proteins which include histone proteins and non histone protein that helps in the packaging of an almost 2m DNA into a very tiny 0.6microm nucleus. The histone protein includes H2A, H2B, H3, H4 which forms an octamer around which the DNA is wrapped (structure of a nucleosome) and linker histone H1 joined to a linker DNA that links two nucleosomes.
