Muscles are the most essential structural component of the human body responsible for movement, structural integrity, posture, joint stabilization, and organ functioning. The three major types of muscles found in the human body are smooth muscles, cardiac muscles, and skeletal muscles.The skeletal muscles along with the skeleton system, form the Musculoskeletal system. A skeletal muscle is made up of muscle fibers along with nerve fibers, blood vessels, and different layers of connective tissue sheaths. The skeletal muscles present in the body are found in diverse shapes and perform diverse functions of adduction, abduction, extension, and flexion of the extremities.Option C is the correct. The increase in muscle size is a result of muscle hypertrophy which occurs due to repair of the damage and injury to the fibres of the muscle caused by increased energy demands on the muscle cells due to prolonged exertion periods. The body repairs the damaged part by the fusion of the muscle cells which also increases the muscle size as well as the number of nuclei in each muscle fiber. Each muscle fiber represents a single cylindrical muscle cell. The multiple nuclei within a muscle cell are necessary to support the increased volume and metabolic demands of a larger cell. These nuclei provide genetic material and resources for protein synthesis. This enables the cell to produce more proteins that can support the size and growth of the muscle cell. These proteins are necessary for various cellular processes like cell structure maintenance, supporting contractile proteins such as actin and myosin, and aiding in cell signaling pathways. Option A is incorrect. The different enzymes (proteins) in the cell break down nutrients as they enter to support the cell. Direct nutrient digestion is not the function of nuclei. Instead, these proteinaceous enzymes that break down nutrients and provide energy for cellular activity are synthesized in nuclei.Option B is incorrect. Energy is not produced by nuclei. Adenosine triphosphate (ATP) molecules, which provide energy in the form of nutrients like glucose, are produced in the cytoplasm through a series of successive enzymatic events.Option D is incorrect. Subcellular components are not transferred across cells by nuclei. Instead, when this transport is needed, nuclei are responsible for producing the proteins that will help.The most likely explanation for the expression of additional nuclei in growing muscle cells is that the addition of more nuclei to the cell will allow more genetic information to be stored in the cell and allow the cell to produce additional types of proteins as its size increases.
