 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).
The culprit is a strain of virus called human papillomavirus or HPV. Many strains of the virus exist, and those that cause common warts on the hands and feet are not the same strains of HPV that cause genital warts. Some people mistakenly think plantar warts or palmer warts are malignant. In fact, they are not harmful.Eventually, in about two years, most warts go away without treatment.ometimes plantar warts can grow in clusters; those are called mosaic warts. Sometimes corns or calluses are mistaken for a palmer or plantar wart. In some warts, little black dots appear, leading people to call them seed warts. Actually the black dots are little blood vessels that have grown up into the wart.
