Question

How does a muscle cell function?

Answer 1

Muscle cells which are also known as myocytes are specialized cells that are present in the muscles and are formed by a process known as myogenesis.

Complete answer:
1.Muscles contain two types of proteinaceous filaments that are actin and myosin that overlap and slide over each other which then leads to contraction of muscle cells that helps in the movement and locomotion by a force generated by the muscles due to myocytes.

2.Small cell myoblasts undergo development to form myocytes which in turn give rise to muscles and this process is known as myogenesis.

3.The cytoplasm of the muscle cells is known as the sarcoplasm and it consists of many muscle fibers, polysaccharide glycogen, and a red pigment known as myoglobin that is responsible for the storage of oxygen. The smooth endoplasmic reticulum of muscle cells is known as the sarcoplasmic reticulum which contains transverse tubules and cisternae and the cell membrane of a muscle cell is termed as sarcolemma which is composed of reticular fibers and the basal lamina.

Note: The muscle cells are mainly classified into two types that are the smooth muscle cells and cardiac muscle cells. The smooth muscle cells that are present in some of the most vital organs of a person such as a stomach, etc are known to regulate various involuntary actions of the body whereas the cardiac muscle cells that are also known as the cardiomyocytes are responsible for the formation of chambers of the heart.
