Explain Muscular Tissue.

1.	Explain Muscular Tissue.
Answer» Muscle tissues consists of elongated cells also called muscle fibres. This tissue is responsible for movement. Muscles contain special proteins called contractile proteins which contract and relax to cause movement. These are elastic in nature they have tensile strength. These muscles can be voluntary or involuntary in function. Muscular tissues are of three kinds namely striated muscles, unstriated muscles and cardiac muscles. Striated muscle cells are long, cylindrical, unbranched and multinucleate. These are voluntary muscles. Smooth muscles or involuntary muscles are found in the iris of the eye, in ureters and in the bronchi of the lungs. These are also called unstriated muscles. The cells are long with pointed ends and uninucleate. Hear muscles or cardiac muscles are cylindrical, branched and uninucleate.
