As with all tissues dependent on a vascular supply, muscles depend on red blood cells to transport oxygen to them. Red blood cells, in turn, rely on an oxygen transport protein called hemoglobin to carry oxygen to all parts of the body.Continue Reading
Hemoglobin is a tetramer, meaning a protein composed of four subunits. Hemoglobin also contains four cofactors called heme, a ring-shaped structure with an iron atom at its center. Iron binds oxygen reversibly, allowing hemoglobin to pick up oxygen in the lungs and drop it off in the tissues where it is needed.
Cardiac and skeletal muscles also contain a protein called myoglobin, which binds oxygen more tightly than hemoglobin. Myoglobin provides the heart and skeletal muscles with an oxygen reserve; this comes in handy during short bursts of physical activity.Learn more about Muscles
The function of tendons is to connect muscle tissues to bones. The same way ligaments connect bones to other bones, tendons act as the bridge between muscles and bones. This connection enables the tendons to regulate forces between muscle tissues during movement so that the body remains stable.Full Answer >
Enthesophytes, also known as bone spurs, are abnormal bone growths that advance into the connective tissues of ligaments or tendons. Common causes of enthesophytes are skeletal stresses such as arthritis, large amounts of physical exercise and inflammatory rheumatic disease.Full Answer >
Tendons are bands of fibrous connective tissues made of parallel collagen fibers. Collagen allows the tendons to be strong and flexible. This is necessary because tendons are stretched tightly when activated.Full Answer >
Muscle deterioration occurs due to the death of muscle cells and muscle tissues, resulting in a genetic disease called muscular dystrophy, according to Medical News Today. The disease causes progressive weakness and degeneration of voluntary muscles.Full Answer >
