Answer:
Muscular Tissue
Muscular tissue is a specialized tissue in animals which applies forces to different parts of the body by contraction. It is made up of thin and elongated cells called muscle fibers. It controls the movement of an organism.
The cytoplasm in the muscle fibers is called sarcoplasm. It contains a network of membrane called the sarcoplasmic reticulum. The membrane surrounding the muscle fibers is called sarcolemma.
Properties of Muscular Tissue:
1.Contractibility– It is the ability of muscle cells to shorten forcefully.
2.Extensibility– A muscle has the ability to be stretched.
3.Elasticity– The muscles have the ability to recoil back to its original length after being stretched.
4.Excitability– The muscle tissue responds to a stimulus delivered from a motor neuron or hormone.
