The distal phalanges, as compared with the distal phalanges of the finger, are smaller and are flattened from above downward; each presents a broad base for articulation with the corresponding bone of the second row, and an expanded distal extremity for the support of the nail and end of the toe.

The coffin bone, also known as the pedal bone (U.S.), is the distal phalanx, the bottommost bone in the front and rear legs of horses, cattle, pigs and other ruminants. It is encased by the hoof capsule. In horses and other odd-toed ungulates it is the third phalanx, or "P3"; in even-toed ungulates such as cattle, it is the third and fourth (P3 ...
Distal phalanges (10 bones in total; 5 on each side) Lower limb (thigh and leg) and foot. There are a total of 8 bones in the legs and 52 in the feet. Femur (2)
The rest of the toes each have three phalanx bones (proximal, middle, and distal phalanges), so they have two interphalangeal joints: the proximal interphalangeal joint between the proximal and middle phalanges (abbreviated "PIP joint") and the distal interphalangeal joint between the middle and distal phalanges (abbreviated "DIP joint").
The bones and joints of the equine forelimb distal to the wrist (or carpus): The fetlock (metacarpophalangeal joint) is located between the cannon bone (third metacarpal) and the long pastern bone (proximal phalanx). The pastern joint (proximal interphalangeal joint) is located between the long pastern bone and the short pastern bone (middle ...
Feet and ankles (52 bones) - Left and right tarsals (14) (ankle), metatarsals (10) (foot), proximal phalanges(10), intermediate phalanges (8) and distal phalanges (10) . Through anatomical variation, the appendicular skeleton may have an accessory bone. Examples include sesamoids in the hands and feet. Some occurrences are rarer than others.
The four fingers each consist of three phalanx bones: proximal, middle, and distal. The thumb only consists of a proximal and distal phalanx. [ 11 ] Together with the phalanges of the fingers and thumb these metacarpal bones form five rays or poly-articulated chains.
However, recently there have been reports that the thumb, like other fingers, has three phalanges, but lacks a metacarpal bone. [3] Has greater breadth in the distal phalanx than in the proximal phalanx; Is attached to such a mobile metacarpus (which produces most of the opposability) Curls horizontally instead of vertically
