Bony Anatomy of Middle Phalanges of the Foot:
The middle phalanges of the foot differ in their structure from the middle phalanges of the hand. They are shorter and more compressed than the middle phalanges of the hand. They are also called intermediate phalanges.
The reason these bones are called phalanges is because of a Greek army formation that resembles their formation. The Greek army would line up in a row that looks somewhat like the toes. The middle phalanges and other bones of the toes are not named individually, but named to represent their location relative to where they are located and their placement in the three rows of the phalanges of the foot. So middle phalanges bones are exactly what they sound like; phalangeal bones located in the middle of the foot. The middle phalanges (foot) bones of the toes are held together by ligaments which assist the muscles in moving the toes when someone walks.
