Define muscular tissue, Classify and explain different types of muscles with the help of suitable diagrams.

Answer :

Muscular tissue: Muscular tissue is a contractile tissue made up of muscles. Muscles consists highly specialised cells called muscle fibres. This tissue is responsible for movement in our body.

Types of muscular tissues:


In human beings, three types of muscles are found:


(a) Striated muscles


(b) Smooth muscles


(c) Cardiac muscles


(a) Striated muscles: Striated muscles are also called voluntary muscles as their movement is under our will. The cells of striated muscles are long, narrow, cylindrical, unbranched with blunt ends. They have multi nucleus.


These muscles are also called skeletal muscles because they are mostly attached to bone and help in body movement. These muscles show alternate light and dark band or striations when stained appropriately. As a result, they are also called striated muscles.



(b) Smooth muscles: Smooth muscles also called as unstriated muscles as they lack transverse striations. They are not under the control of one’s will, hence they are also called involuntary muscles. These muscle cells are long with pointed ends (spindle shaped) and arranged in bundles. Each cell is uninucleated (having a single nucleus).


Smooth muscles are found in alimentary canal and blood vessels. The movement of food in the alimentary canal or the contraction and relaxation of blood vessels are involuntary movement. These are also found in the iris of the eye, in uterus and in the bronchi of the lungs.



(c) Cardiac muscles: These muscles are exclusively present in the heart. These muscles of the heart show rhythmic contraction and relaxation throughout life. They are striated but involuntary muscles. Heart muscle are cylindrical and uninucleated. They are branched and form a network in the walls of the heart.
