 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 on the feet are called verrucas (or verrucae) and are sometimes painful. Warts and verrucas usually clear in time without treatment. If required, they can often be cleared more quickly with treatment. Most commonly, treatment involves applying salicylic acid or freezing with liquid nitrogen or a cold spray.
