Functions of Muscles

In this article we will discuss about the functions of muscles

Functions of Muscles

• There are three types of muscle tissues in animal
  1. Skeletal muscle
  2. Cardiac muscle
  3. Smooth muscle

Skeletal Muscle Function

• Skeletal muscle is responsible for all voluntary actions of the body.
• By pulling on tendons, they then produce movement of the skeleton.
• Maintaining posture and body position
• Support soft tissues and store nutrient reserves
• Skeletal muscles protect the internal organs from injury.

Smooth Muscle Function

• All involuntary activities are responsible for smooth muscles because they are controlled by signals from the autonomous nervous system.
• Smooth muscles in the gut enable food to move through the alimentary canal of the digestive system.
• The smooth muscles regulate body temperature.
• Smooth muscle muscles help with the flow of blood in the arteries and veins.
• In the urinary bladder, smooth muscle helps to push out urine.
• During menstruation, smooth muscle in the uterus contracts to expel the uterine lining.
• Smooth muscle helps sperm to move along the male reproductive tract.
• To prevent urination during ejaculation by men, the sphincter muscle constricts.
• The smooth muscle in the uterus helps a woman to push out her baby.
• Smooth muscle cells in the ovaries contract when a woman ovulates.

Cardiac Muscle Function

• Cardiac muscle tissue helps to keep your heart pumping through involuntary movements.
• Cardiac muscles are found only in the heart
• It also helps in the flow of blood.
• They regulate the contraction and relaxation of the heart, which helps in pumping blood through the circulatory system.
• The cardiac muscle tissue works without stopping, day and night.
• The movements of the cardiac muscles are involuntary. They are important in sustaining life.
