How they differ along the set
What changes from one end of the series to the other, which is most of what there is to know about any one of them.
- The phalanges and sesamoid bones of the hindpaw are so like those of the forepaw that the book gives them no separate description.Miller 2020, p. 365
- Each of the four main digits has three phalanges; the first digit has two.Miller 2020, p. 330
- Every phalanx is read the same way: a base at the top, a body, and a head below.Miller 2020, p. 330
- A middle phalanx is about a third shorter than the proximal phalanx it meets.Miller 2020, p. 330
- The base of a middle phalanx carries a smaller sagittal ridge, lower tubercles and a shallower groove than a proximal one.Miller 2020, p. 330
- The distal phalanx is about the same size in all four main digits, and smaller in the first.Miller 2020, p. 330
- A broad low tubercle on the underside of the distal phalanx takes one of the five slips the deep digital flexor divides into, and a vascular canal pierces the bone to either side of it.Miller 2020, p. 330
- Two sesamoid bones lie behind each main metacarpophalangeal joint, in the tendons of the interossei; the first digit has a single bead.Miller 2020, p. 331
