Individual fringes may attain the size of a hazel nut, and the fibro-fatty tissue of which they are composed may be converted into cartilage and bone; such a body may remain attached by a narrow pedicle or stalk, or this may be torn across and the body becomes loose and, unless confined in a recess of the joint, it wanders about and may become impacted between the articular surfaces.
The inner surface is united more or less closely to the muscular or underlying tissue by a layer of fibro-fatty tissue. The appendages of the skin are the hairs and horny productions. The horny productions comprise the horns, chestnuts, ergots, claws and hoofs. The hair varies in length, thickness and coarseness in the different species, and the different regions of the body.

The orbit is lined by fibro-fatty tissues that form a cushion for the eye. Anteriorly it is protected by the eyelids, and in birds by a third eyelid that corresponds to the membrana nictitans of quadrupeds.
