BODY-BUILDING Body-building is a growing sport worldwide. Once considered only for men, it currently is enjoyed by thousands of women as well. Participants in this sport combine diet and specific weight training to develop maximum muscle mass and minimum body fat. Thus all skeletal muscles must be developed to their maximum. It is relatively simple for the uniformed, untrained muscle builder to build some muscles and ignore others; the result is a disproportioned body. Skill, training, and concentration are required to build all the muscles, to know which exercises build a large number of muscles and which are specialized to build certain parts of the body. Body-building has its own language in which it is improper to refer to a muscle by its full name. Body-builders refer to the “lats”, “traps”, and “delts” rather than the lattissimus dorsi, trapezus, and deltoids. Body-builders concentrate on increasing skeletal muscle mass. Endurance tests conducted several years ago demonstrated that the cardiovascular and respiratory abilities of body-builders were similar to those abilities in normal, healthy persons untrained in a sport. However, more recent studies of American scientists indicate that the cardio-respiratory fitness of body-builders is similar to that of other well-trained athletes. The difference between the new studies and the older studies is attributed to modern body-building techniques that include aerobic exercise. Photographs of body-builders are very useful in the study of anatomy to identify easily the surface anatomy of muscles that cannot be seen easily in untrained people.
OVERVIEW There are 650 muscles in the human body. The muscle consists of muscle cells, muscular fibers, connective tissue, blood vessels, and nerves. The muscles are divided into three major parts: skeletal, cardiac, and smooth. Skeletal muscles move the trunk, the head, and the limbs; the cardiac muscles propel blood through vessels; and smooth muscles propel food through the digestive system. The skeletal muscles are controlled by our consciousness. Smooth and cardiac muscles contract spontaneously. As for the form of the muscles they can be long, short, and wide. The long muscles form the limbs, the short ones compose the facial part, and wide muscles are on the trunk and form the walls of the body cavities. Muscles are attached to bones, internal organs, and blood vessels. Most skeletal muscles extend from one bone to another. Some muscles of the face are attached to the skin. Muscles are named according to their location, size, number of heads, or function.

Ex. 4. Read the following text: WOUNDS There are some types of wounds. They are tears, cuts, stabs, contused wounds, and gunshot wounds. Tears occur when the skin is pulled beyond the limits of its elasticity. The edges of the wound are irregular. Tears are usually caused by sharp-edged objects such as broken glass. Deep tears can damage nerves and blood vessels. Cuts are caused by action of sharp object. Stabs are caused by pointed objects, which penetrate into the tissue. External bleeding is usually not severe, but there might be severe internal bleeding. The wound edges are generally stuck together and do not gape. Contused wounds occur when a blunt force acts on the soft parts, with bones a short distance underneath, so that the soft parts are held between the force and the bones. If the edges of the wound are close together, the wound heals by a process called primary union. If the edges are not close together or if there has been extensive loss of tissue, the process is called secondary union. In the primary union the wound fills with blood, and clots form. The clot contains a fibrin, which binds the edges of the wound together. The surface of the clot dries to form a scab, which seals the wound and helps prevent infection. Fibrin and blood cells move into the wounded tissues. The fibrin acts to isolate microorganisms and other foreign substances. Some of the white blood cells (phagocytic cells called neutrophils) ingest bacteria, thus helping to fight infection. They also ingest tissue debris, clearing the area for repair. Neutrophils are killed in this process and may accumulate a mixture of dead cells and fluid called pus. After a few days the epithelial cells from the edges meet, forming a single layer of cells over the wound. As the new epithelium forms, a second type of phagocytic cell removes the dead neutrophils and cellular debris. Then the clots are replaced by a connective tissue (granulation tissue). A large amount of granulation tissue sometimes persists as a scar. Repair by secondary union is similar to healing by primary union, but there are some differences. Because the wound edges are far apart, the clot may not close the gap completely. Much more granulation tissue forms and wound contraction reduces the size of the wound and speeds healing. Wound contraction can lead to disfiguring scars. Thus it is reasonable to suture a large wound so that it can heal by primary rather than secondary union. Healing will be faster, the risk of infection will be lowered, and the degree of scarring will be reduced.

Ex. 17. Read the following text and get ready to narrate it: EMERGENCY CARE OF WOUNDS Cuts. If you sustain a small cut that bleeds only slightly, wash the cut thoroughly with mild soap and water. Apply a bandage to keep it clean. If the cut is more serious you must stop bleeding by applying pressure directly to the injury, using a sterilized gauze pad or clean cloth. Maintain pressure on the wound until the bleeding stops. Stabs. A stab doesn’t usually result in excessive bleeding. Often little blood will flow and the wound will seem to close almost instantly. These features, however, do not mean that treatment is unnecessary. Stabs are dangerous because of the risk of infection. The object that caused the wound may carry spores of the tetanus or other bacteria. These can result in serious infections. If you sustain a stab, stop the bleeding, if necessary, by applying pressure with a sterilized gauze pad or clean cloth. Then seek emergency care for appropriate treatment to prevent tetanus or other infection. Soft tissue injuries. These injuries may involve considerable bleeding. The skin is damaged, as are underlying tissues such as muscle, supporting structures, and blood vessels. Such injuries can occur when an area is struck and badly cut, when the skin is separated from the underlying tissues, or when areas of the skin are forcefully torn away. Soft tissue injuries require special treatment at the hospital or polyclinic. OVERVIEW There are some types of wounds. They are tears, cuts, stabs, contused wounds, and gunshot wounds.
