Human Anatomy
The knee is a hinge type synovial joint, which is composed of three functional compartments: the femoropatellar articulation consists of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral femorotibial articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower leg. The joint is bathed in synovial fluid which is contained inside the synovial membrane called the joint capsule. The posterolateral corner of the knee is an area that has recently been the subject of renewed scrutiny and research.
The knee is one of the most important joints of our body. It plays an essential role in movement related to carrying the body weight in horizontal (running and walking) and vertical (jumps) directions.
Upon birth, a baby will not have a conventional knee cap, but a growth formed of cartilage. In females this turns to a normal bone knee cap by the age of 3, in males the age of 5.

Famous quotes containing the words human and/or anatomy:
“Fielding being mentioned, Johnson exclaimed, “he was a blockhead ....” BOSWELL. “Will you not allow, Sir, that he draws very natural pictures of human life?” JOHNSON. “Why, Sir, it is of very low life. Richardson used to say, that had he not known who Fielding was, he should have believed he was an ostler.””
—Samuel Johnson (1709–1784)
“But a man must keep an eye on his servants, if he would not have them rule him. Man is a shrewd inventor, and is ever taking the hint of a new machine from his own structure, adapting some secret of his own anatomy in iron, wood, and leather, to some required function in the work of the world. But it is found that the machine unmans the user. What he gains in making cloth, he loses in general power.”
—Ralph Waldo Emerson (1803–1882)
