Question

Explain Muscle Tissue with the help of a Diagram.

Answer 1

here are 3 types of muscle tissue:

Skeletal muscle tissue,

Cardiac muscle tissue, and

Smooth muscle tissue

Skeletal muscle tissue

Function:

Movement of the skeleton under conscious control, including movement of limbs, fingers, toes, neck, etc.

Movement of tissues of facial expression under conscious control, e.g. ability to smile and to frown.

Cardiac muscle tissue

Function:

Pumping of blood through the heart: Alternate contraction and relaxation of cardiac muscle pumps

De-oxygenated blood through the Right Atrium and Right Ventricle to the lungs, and

Oxygenated blood through the Left Atrium and Left Ventricle to the aorta, then the rest of the body.

Smooth muscle tissue

Functions:

Contractions of smooth muscle constrict (i.e. narrow = reduce the diameter of) the vessels they surround. This is particularly important in the digestive system in which the action of smooth muscle helps to move food along the gastrointestinal tract as well as breaking the food down further. Smooth muscle also contributes to moving fluids through the body and to the elimination of indigestible matter from the gastrointestinal system.
