Types of Muscles

muscles

The muscular system is an organ system that is responsible for the movement of the body. It also controls blood flow and maintains posture. In vertebrates, the muscular system is controlled by the nervous system, although some muscles can be autonomous. Learn more about your muscles and their function in this article. Here are a few examples of the different types of muscles.

Actin

Actin is a spherical protein that is involved in muscle contraction and many other cellular processes. It forms a bond with myosin and slides past it during muscle contraction. This process is triggered by ATP.

Myosin

Myosin is a protein that is present in muscle cells. It works with actin to produce force in muscle contractions. Muscle contraction occurs when a nerve sends a signal through the cell membrane to activate myosin. Myosin hydrolyzes ATP, the energy that allows muscles to contract. It also plays an important role in regulating muscle contraction.

Smooth muscle

Smooth muscle is a group of contractile tissues that are located throughout the body. It is believed to regulate body temperature by raising the hair on the skin when it is cold. In some cases, a disorder of smooth muscle is responsible for the development of a fatal disease known as Multisystem SMD. It is a rare hereditary disease characterized by a generalized cognitional disorder of smooth muscle throughout the body.

Cardiac muscle

Cardiac muscle is composed of large elongated mitochondria. These structures are located between the myofibrils and have several internal cristae. Cardiac muscle also contains extra glycogen granules that serve as stores of energy. The tissue also has collagenous tissue fibers and capillaries that provide the cells with blood supply.

Visceral muscle

Visceral muscle is the kind of muscle that surrounds our internal organs and digestive tract. These muscles are involuntary and are often not controlled by our conscious minds. They are found around the abdomen, blood vessels, GI tract, respiratory system, and urination system. Most of them are oval-shaped and are present in the walls of internal organs.

Skeletal muscle

Skeletal muscle is a component of the human musculoskeletal system. It connects bones and organs to perform movement and is responsible for maintaining homeostasis in the body. Skeletal muscles are made up of long muscle cells, also called muscle fibers. These muscle cells are arranged in striated patterns, which give them a striped appearance under a microscope.
