Question
3 types of muscles and their characteristics and locations (skeletal / cardiac / smooth)
Solution
-
Skeletal Muscle: These are also known as striated muscles due to their appearance under a microscope. They are attached to bones by tendons and they help in body movements. They are voluntary muscles, which means we can control their contraction and relaxation. They are long, cylindrical, and have multiple nuclei.
-
Cardiac Muscle: These muscles are found in the heart. They are also striated but unlike skeletal muscles, they are involuntary. This means their contraction and relaxation are not under our conscious control. They are responsible for the rhythmic contraction and relaxation of the heart. They are branched and have a single nucleus.
-
Smooth Muscle: These muscles are found in the walls of hollow organs like the stomach, intestines, blood vessels, etc. They are not striated and are involuntary. They help in various functions like the movement of food through the digestive tract, dilation and constriction of blood vessels, etc. They are spindle-shaped and have a single nucleus.
