 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).
Similar in appearance are warts on the palms (palmar warts). Small warts growing in clusters on the plantar surface of the foot have been called mosaic warts. Flat (plane) warts may arise on the face, legs, and other parts of the body, often in large numbers. Periungual warts are warts around or under the nail.
