Cardiac muscle tissue – this is the only type of muscle tissue that contains intercalated discs. These discs connect the adjacent cardiac muscle cells. It also appears as branched and contains muscle fibers with single nucleus. It is found surrounding the heart and causes the mechanical pumping of the heart which is an involuntary movement.
Skeletal muscle tissue – this type of muscle tissue is cylindrical, multinucleated and striated. Its striations are due to the actin and myosin overlapping. Also, due to it being multinucleated it has an increased production of uric acid. It contains myofibrils which are the muscle proteins. It is found between bones and moves voluntarily. It is also used for maintenance of body posture and heat protection.
Smooth muscle – is not striated and branched. It contains one nucleus and is involuntarily controlled. It can be found in the stomach and intestines where it plays a role in the digestion of food and collection of nutrients. It is also found in the urinary tract where it functions in getting rid of toxins and in electrolyte balance. Furthermore, it regulates the blood flow in the heart and is active during contraction of the genitalia during pregnancy.
