How many phalanges are in the hand and foot?
In primates, the thumbs and big toes have two phalanges while the other digits have three phalanges. The phalanges are classed as long bones . The phalanges are the bones that make up the fingers of the hand and the toes of the foot. There are 56 phalanges in the human body, with fourteen on each hand and foot.
How are the phalanges of the hand interconnected?
There are fourteen phalanges in each hand; each of the medial four digits has three phalanges (proximal, middle and distal), while the thumb has only two (proximal and distal). The phalanges are interconnected by interphalangeal joints and vascularized via the nutrient rami to phalanges, which stem from the palmar digital arteries.
Where does the body appear in the distal phalanx?
In the distal phalanges of the hand the centres for the bodies appear at the distal extremities of the phalanges, instead of at the middle of the bodies, as in the other phalanges. Moreover, of all the bones of the hand, the distal phalanges are the first to ossify. This section needs expansion. You can help by adding to it. (January 2014)

So, there are fourteen phalanges in each hand, meaning their total number in both hands is twenty-eight.
How many bones make up the phalanges in one hand?
Human hands contain fourteen digital bones, also called phalanges, or phalanx bones: two in the thumb (the thumb has no middle phalanx) and three in each of the four fingers. These are the distal phalanx, carrying the nail, the middle phalanx, and the proximal phalanx.
Are the phalanges referred as the fingers and toes?
