There is the outer or lateral claw and the inner or medial claw. In cattle, the lateral claw is slightly larger on the back feet, while the medial claw is the larger claw of their front feet. The space between the two claws is called the interdigital clef; the area of skin is called the interdigital skin. The different surfaces of the claws are named according to their relative position to the interdigital cleft: The abaxial surface is the outer wall of each claw, and the axial surface is the inner wall. The hoof is described from the outside moving in. Beginning with the hard outer covering of the hoof, known as the hoof wall or horn. The horn is a hard surface, structurally similar to the human fingernail, but functioning like the epidermis of the skin. The cells that form the horn are produced by the tissue directly beneath the hoof wall, called the corium, at the hoof head. The corium is a nutrient-rich tissue that contains many important blood vessels and nerves inside the hoof. The corium is similar to the quick of the fingernail in humans in that it continuously produces new cells that are then gradually pushed away from the quick. As the cells are pushed away from the corium they die and produce the hard, new outer growth that we see both in our own nails and in hoof growth. At this point the cells are said to have been keratinized or cornified. As a general rule, bovine hooves grow about 1/5 to ¼ of an inch per month. Cow hooves also serve a purpose to humans also. People have made them into soup, tools, and even shoes. It’s not really my thing, but hey, creativity is good isn’t it?
Don't think I've forgotten about the larger animals. Because, this week I'm writing about cow hooves. Cattle, sheep, goats, and pigs are cloven-footed animals. Meaning that the hoof consists of two digits instead of one solid entity like that of a horse. The two digits are analogous to the third and fourth fingers of the human hand. The claws are named by their relative location on the foot.
