The knee has been called "a beauty and a beast." Provide several reasons that might explain the negative (beast) part of this description
Weegy: Beast since the human knee supports most of the weight in the body, and is thus a joint most vulnerable to injury and development of bone and ligament disease. [ Also, an overwhelming number of knee procedures are both very complicated and very painful. ] (More)

Why are sprains and cartilage injuries a particular problem?
Weegy: Sprains involve stretching or tearing of joint ligaments. Because ligaments are poorly vascularized, healing is slow. Cartilage injuries, particularly of the knee, are common in contact sports and may result from excessive twisting or high pressure. [ The avascular cartilage is unable to repair itself.[wink] ] (More)

Jim Fitch decided that his physique left much to be desired, so he joined a local health club and began to "pump iron" three times weekly. After three months of training, during which he was able to lift increasingly heavier weights, he noticed that his arm and chest muscles were substantially larger. Explain the structural and functional basis of these changes.
Weegy: Weight training provides us with exercises that take skeletal muscles through their normal range of motion. [ So, structurally, when a muscle is worked against a resistance it is not accustomed to, it will begin to adapt to the resistance, and neuromuscular facilitation will also occur. There are two theories I am familiar with that deal with muscular growth. The first is hypertrophy, where individual muscle fibers become bigger, therefore making the muscle bigger. The other theory is hyperplasia, which is the dividing of a muscle fiber. When thousands of muscle fibers divide, this will also make the entire muscle larger. Because Jim challenged the muscle by increasing the weights gradually, the muscle was able to adapt gradually. Overtraining must not have occured here. He allowed the muscle time to recover before working it again. I hope this helps you. ] (More)
