Question

Mention the six different properties of skeletal muscle ?

Accepted Answer

A skeletal muscle is a type of muscle that is attached to the bones. These muscles have alternate dark and light striations and are called striated muscles. The control of the skeletal muscles is under the control of the will of an individual. Thus, they are also called voluntary muscles. The properties of the skeletal muscle are:

The term multinucleate refers to the presence of more than one nucleus within a single cell. The cells of the skeletal muscles or striated muscles are multinucleated cells as they contain more than one nucleus in the cell, unlike the smooth or cardiac muscle cells.

Sarcoplasm is the cytoplasm of muscle fibre. It is a water solution containing contractile proteins, ATP, enzymes, and intermediate molecules involved in many metabolic reactions of the muscle. The most abundant metal in the sarcoplasm is potassium.

Excitability is the ability to respond to a stimulus, which may be delivered from a motor neuron or a hormone. Extensibility is the ability of a muscle to be stretched. Elasticity is the ability to recoil or bounce back to the muscle's original length after being stretched.

Fatigue is the feeling of over tiredness with extremely low energy. Muscle fatigue is the decline in the ability of muscles to generate force. It can be a result of vigorous exercise, but abnormal fatigue may be caused by barriers to or interference with the different stages of muscle contraction.
