3.1 INTRODUCTION OF MUSCULAR SYSTEM.
Muscles tissue do is done by the coordinated contraction and release of millions of sarcomeres, tiny structures within the muscles cells. Muscle activity accounts for the most of the body’s energy consumption. All muscles tissues is strong. Most is enduring, some of it astoundingly so. Its cells are crowded with mitochondria, thousands of little factories constantly turning out molecules of ATP, a refined fuel.
There are three types of muscles that can be found in our body. Skeletal muscles, cardiac muscles and smooth muscles are the basic muscles that we must know.
It responsible to contract or shorten and are the machine of the body. In the inside of our body, muscles are attached …show more content…
The strength of the skeletal muscles like fibrous material of every kind came from assembling individual fibers together into strands, and then bundling and rebundling the strands. The strands are made of protein, and they renew and repair themselves constantly.
SMOOTH MUSCLES:
The organs and structures of many organ systems, including the digestive system, the urinary system, the respiratory system, the circulatory system, and the reproductive system lined by smooth muscles tissue. Smooth muscle contraction is typically slow, strong, and enduring. Smooth muscle can hold a conctraction longer than skeletal muscles. Smooth muscle cells aren’t triated.
CARDIAC MUSCLES:
Muscles tissues of heart called cardiac muscles. The cells (fibers) in cardiac muscle contain one nucleus (they’re uninucleated) and are cylindrical: they may be banched in shape unlike skeletal muscle, where the fibers lie alongside one another, cardiac muscle fibers interlock, which promotes the rapid transmission of the contraction impulse throughout the heart. Contraction of the heart muscle is autonomous, which means it occurs without stimulation by a nerve. In between contractions, the fibers relax …show more content…
This muscle is shaped like a triangle. Activities that include deltoids muscle are dribble, shooting a basket, chest pass and free throw. The functions of deltoid muscle are to help raise our arm up to the side. In basketball deltoid is important because to shoot into the basket, a strong muscle deltoid are needed and also needs some supporter muscles as like triceps and others. The chest pass, which resembles a pushup motion, is a common way to get the ball to another player. The elbow extensors, including the triceps, pectoral and deltoid muscles, work in concert as an isotonic contraction to enable you to make a chest pass to another
