Pls tell 10 points on muscular tissue |
| Answer» 1) Muscular tissue is composed of muscle cells.2) Muscle cells are specialized cells which have the capability to contract and expand.3) Due to contraction and expansion, muscles facilitate various kinds of movements in the body.Muscular tissues are of three types:Striated Muscles: The cells of striated muscles are in the form of long, unbranched fibres. Cells are multinucleate. Light and dark bands (striations) are present on muscle fibres; which gives the name striated muscles. Striated muscles are found in those organs where voluntary movement is possible, e.g. hands, legs, back, neck, etc.Smooth Muscles: The cells of smooth muscles are spindle shaped and each has one nucleus. Smooth muscle is found in those organs where involuntary movement is possible, e.g. alimentary canal.Cardiac Muscles: The cells of cardiac muscles are in the form of branched fibres. Striations are present and cells are uninucleate. These are found in the heart. Cardiac muscles are capable continuous contraction and relaxation throughout the life. | |
