', 'Support – the skeleton keeps the body upright and provides a framework for muscle and tissue attachment.', 'Protection – the bones of the skeleton protect the internal organs and reduce the risk of injury on impact.']

Muscles move the body by contracting against the skeleton. When muscles contract, they get shorter. By contracting, muscles pull on bones and allow the body to move. Muscles can only contract.

The chest wall consists of the muscles of respiration—such as the diaphragm, the intercostal muscles, and the abdominal muscles—and the rib cage. The functions of the respiratory system include gas exchange, acid-base balance, phonation, pulmonary defense and metabolism, and the handling of bioactive materials.

The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.

Skeletal muscle is a voluntary muscle, which means that we can actively control its function. It's attached to the bone and forms a distinct organ of muscle tissue, blood vessels, tendons, and nerves that covers our bones and allows movement.

Skeletal muscles maintain posture, stabilize bones and joints, control internal movement, and generate heat. Skeletal muscle fibers are long, multinucleated cells. The membrane of the cell is the sarcolemma; the cytoplasm of the cell is the sarcoplasm.

In the musculoskeletal system, the muscular and skeletal systems work together to support and move the body. The bones of the skeletal system serve to protect the body's organs, support the weight of the body, and give the body shape.

Muscle fibers consist of a single muscle cell. They help to control the physical forces within the body. When grouped together, they can facilitate organized movement of your limbs and tissues.

Skeletal System It also consists of all the joints, cartilage, tendons, and ligaments within the body. The primary functions of the skeletal system are locomotion, support of the body, and the protection of internal organs such as the brain, heart, and lungs.

Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions.

Function. The facial muscles differ widely from the other skeletal muscles because they do not move joints but instead the skin. The muscles of the mouth are mainly responsible for the elevation and depression of the angle of the mouth, upper and lower lips and the opening and closure of the mouth.

At this basic level, the cells in our bodies are maintaining the basic functions of life, and lack of movement interrupts our bodies' ability to carry on these functions. Movement keeps blood flowing, bringing in nutrients and pumping out waste for every system in the body.

Major functions of connective tissue include: 1) binding and supporting, 2) protecting, 3) insulating, 4) storing reserve fuel, and 5) transporting substances within the body. Connective tissues can have various levels of vascularity.
