 The most common joint type is the diarthrosis of articulating joints, which has a fibrous connective tissue capsule (ligament), continuous with the periosteum of the two bones and which permits a degree of freedom of movement between the two bones.
Verruca: A wart by another name, a local growth of the outer layer of the skin (the epidermis) caused by a virus. The virus of warts (a human papillomavirus) is transmitted by contact. The contact can be with a wart on someone else or one on oneself (autoinoculation).
Warts are viral infections of the outer layer of the skin caused by the human papilloma virus (HPV) . Warts are more common in children because children have less developed immune systems than adults. Most people develop only a few warts, but, in some cases warts become large and cover many areas of the body. Warts are contagious but contrary to popular myth they are not spread by frogs.
