Exercise 8. Read the text and complete the table giving the definitions of the muscles.
Vertebrate muscles are given names derived from Latin according to their attachments. In this system the Latin names of the bony points of attachment are either joined, or they may be named for their form or their gross function. There are several standard terms that describe form and function. A muscle may have more than one point of origin; thus, it may be described as having, for example, two heads, as in biceps femoris (bi - for two, -ceps or heads, femoris meaning of the femur). It may be long, longus, or short, brevis. It may run transversely across a body segment, transversus, or obliquely, obliquus. It may lie close to the surface, superficialis, or deep, profundus. In describing function, lexors are muscles that tend to close the angle made by the two bones to which they are attached; extensorstend to increase the angle. Adductors pull a bone or cartilage closer to the axis of the body, or limb, while abductors pull away from the axis. Rotators turn one bone or cartilage with respect to another or with respect to the midline. Pronators turn the sole of the foot or the palm of the hand to face the ground, while the opposite function is performed supinators. Constrictors and sphincters diminish the volume of spaces or the area of structures, and dilators increase them.

Exercise 9. Read the text and prepare the talk Tendons and Ligaments: How to Prevent Tendon/Ligament Injury (4-5 min).
Ligaments and tendons are part of the musculoskeletal system, with ligaments attaching bones to bones and tendons muscles to bones. They each serve very important functions to the joints and bones. Ligaments and tendons are made of dense layered collagen fibers, called fibrous connective tissue. Although collagenous tissues are sturdy, applying excessive force on either the ligament or tendon can cause serious injuries. Ligaments serve as connectors, linking the ends of bones together at a joint. The joints allow for the performance of simple and complex motions throughout the body, and ligaments come in a variety of sizes and shapes to support, strengthen and stabilize the joints.

Tendons attach muscles to bones. Tendons aid in the movement of bones by transmitting force from the muscle to the bone. Tendons aid in a wide range of motion and act to resist pressures; hence, it is important that they vary in shape and size.
Rupture of Ligament
When ligaments receive force greater than their resistance capacity, the collagenous tissue will over-stretch or tear, either partially or completely, thus resulting in injuries. A stretched or torn ligament," also known as sprain, occurs most frequently in the ankle and wrist. The healing process involves three overlapping phases1. In the first phase, bleeding and clotting of blood2occur. Inflammation of tissues also takes place at the injury site. In the second phase, the matrix and fibroblastic cells3replicate excessively, and in the final phase, the matrix remodels itself and matures over time.
Rupture of Tendon
Similar to the ligaments, when tendons receive force greater than their resistance capacity, injuries will result with the tearing and over-stretching of tissues. A strain, which refers to a stretched or torn tendon can develop over time or occur abruptly. The healing process of tendon injuries involves three simultaneously occurring phases. In the first phase, inflammation at the injury site occurs and the growth of new blood vessels and collagen begins. In the second phase, the rapid reproduction of reticular fibers4occurs at its maximum level, and in the final phase, remodeling occurs. New cells will differentiate into fibrous tissue and will eventually mature into a scar-like tendon tissue5.

2. bleeding and clotting of blood -

CAT TAILS
Read the text to find out:
- a number of bones in cats tail;
- the location of tail muscles;
- type of muscle to which caudal muscles belong;
- when cats sway back and forth their tails;
- types of emotional response cat's tail movements signify;
- if your cat has the ability to trigger voluntary muscles and make his tail move.
You can tell a lot by looking at your cat's tail - much more than just which way he's facing. Cats flick, twitch, swish and wiggle their tails to express a range of moods and emotions. Some of these movements are voluntary, but others seem to require little conscious thought.
Cat tails are more complex than meets the eye. Depending on the breed, your cat has 18 to 23 bones in his tail, which is actually an extension of his spine. Tail muscles rest below the lumbar vertebrae, lower-back sacrum and tail vertebrae and attach via tendons. Although this facilitates articulate movements, part of the tail's musculature also is associated with the rectum, anus and pelvic diaphragm.
Caudal muscles are striated and, as such, afford voluntary movement, although some conditions, mental or physical, may cause involuntary movements. The tail nerves collect in a bundle together with those from his hind legs and rear before they collect into the spinal cord. So, on the one hand, your cat's tail can be articulated with great nuance. On the other hand, it's strongly linked to other movements.

If you've ever watched your cat stalk a bird from a windowsill, you know your friendly feline is actually an accomplished hunter. You also probably know his tail sways back and forth when he's in hunting mode. This movement, which starts as a voluntary thought, appears to continue as a primal brain script.
While many of your cat's tail movements signify emotional responses - a wide wiggle is agitation, a sharp twitch is anger, a raised, wavy tail is happiness - others are more pragmatic. Your cat uses his tail as a counterweight, just like a tightrope walker uses her pole.
Cat tails are mood rings. Different wiggles mean different things, whether it's the cat wagging the tail or the tail wagging the cat. Biologically, your cat clearly has the ability to trigger voluntary muscles and make his tail move. Still, once engaged in higher-level thinking, primitive scripts appear to run on their own momentum, or when enacted by surprise events. So does your cat have to think to wiggle his tail? It appears he can do that, but that it requires so little thought that it blurs the line between conscious and unconscious thought.
Exercise 10. Look through the text to find out who this text is intended for:
1) general reader;

Exercise 11. Concentrate on discovering the authors main idea. Select the statement which best expresses the authors main idea:
1. Cats wag their tails for many reasons. In most cases, it's simply for communication purposes.
2. A cat's tail is an extension of his body, so it's used in maintaining balance.
3. To wiggle the tail requires so little thought that it blurs the line between conscious and unconscious thought.
