The middle phalanges (foot) are some of the smaller long bones that form the toes of the feet. They are positioned between the distal phalanges (which are the tips of the toes) and the proximal phalanges (which are the ones that are nearest to the foot itself). 

Four out of the five toes of the foot have middle phalanges, with the exception being the big toe  (first toe) on the foot. They are also called intermediate phalanges. They are called phalanges after an old Greek term for a military formation where the soldiers stood all in a row, somewhat like a row of toes would look. Phalanges aren't individually named; they merely take on the name of the part of the toe they are located in and the position they take up. So, the middle phalanges are exactly what they sound like: phalanx bones that are 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 a person walks.
