Phalanges. The 14 bones that are found in the fingers of each hand and also in the toes of each foot.
How do you identify phalanges?
The digits are named in a similar fashion to the metacarpals, moving lateral to medial, and starting at the thumb. With the exception of the thumb, each digit contains a proximal, intermediate, and distal phalange; the thumb lacks an intermediate phalange. The length of the phalanges decreases distally.
How are phalanges numbered?
Again, like the metacarpals they are numbered I to V, moving from lateral to medial. There are a total of fourteen phalanges in the five digits of each hand; and, a single bone of a digit is referred to as a phalanx. Like the metacarpals, the digits are composed of a proximal base, intermediate shaft, and distal head.

What are the interphalangeal joints of the foot classified as?
The interphalangeal joints of the foot are classified as uniaxial hinge joints, which are a type of synovial joint that permit movement along one axis, in this case flexion (plantarflexion) and extension (dorsiflexion) of the middle and distal phalanges.
What is the difference between the distal and hand phalanges?
The distal phalanges are flatter and smaller than the ones in the hand. They consist of a broad base for articulation with the middle phalanges as well as a non-articular head. A rough, crescent shaped tuberosity is present on the plantar surface of the heads, which supports the pads or pulps of the toes.
What is the development of the middle phalanges?
The development of the middle phalanges usually occurs soon after their proximal counterparts. Deformities of the toes can cause disabling pain and almost always occur in the lateral four toes.
