The dermis of the horse – the layer of tissue below the epidermis, or outer layer of skin – is significantly thicker than that of humans.

What is the strongest bone in a horse?

Cannon Bone – This is the strongest bone in the horse’s body. Articulates with the 2nd row of carpal bones and forms the carpal/metacarpal joint. Distally articulates with the long pastern bone and joins with the fetlock joint.

Why is a horse called a coffin bone?

The “coffin bone” gets its name because it is encased in the hoof like a corpse in a casket. The word “coffin” dates from the early 14th century, is French in origin, and is related to the Latin and Greek words cophinus and kophinos, meaning “basket”.

Are the radius and ulna fused in humans?

Human forearms are made out of two bones – the ulna and the radius. These bones are separated in humans, giving us a range of movement that’s lacking in many other creatures. Goats, horses, and bats have semi-fused ulnae and radii, probably for running and flying, respectively.
