Some authors state that short bones are only located in the carpals and tarsals. [3] The metacarpals , metatarsals and phalanges are considered long bones as they have a shaft (tubular diaphysis), but since they're smaller than typical long bones, they're called “miniature, small or short" long bones.
A short bone is one that is cube-like in shape, being approximately equal in length, width, and thickness. The only short bones in the human skeleton are in the carpals of the wrists and the tarsals of the ankles. Short bones provide stability and support as well as some limited motion. [1]
It is composed of 270 bones at the time of birth, [2] but later decreases to 206: 80 bones in the axial skeleton and 126 bones in the appendicular skeleton. 172 of 206 bones are part of a pair and the remaining 34 are unpaired. [3] Many small accessory bones, such as sesamoid bones, are not included in this.
The number of bones varies according to the method used to derive the count. While some consider certain structures to be a single bone with multiple parts, others may see it as a single part with multiple bones. [5] There are five general classifications of bones. These are long bones, short bones, flat bones, irregular bones, and sesamoid bones.
Endochondral ossification is responsible for development of most bones including long and short bones, [4] the bones of the axial (ribs and vertebrae) and the appendicular skeleton (e.g. upper and lower limbs), [5] the bones of the skull base (including the ethmoid and sphenoid bones) [6] and the medial end of the clavicle.

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 ...
Bones of the lower limb, present in both the front and hind legs, include the cannon bone (3rd metacarpal/3rd metatarsal), splint bones (2nd and 4th metacarpal/metatarsal), proximal sesamoid bones, long pastern (proximal or 1st phalanx), short pastern (middle or 2nd phalanx), coffin bone (distal or 3rd phalanx), and navicular bone (distal ...
