What kind of bone is a metacarpal?
The metacarpal bones are five in numbers and anatomically placed in the hand (in palm). Hence it makes a total of 10 metacarpal bones in two hands.The metacarpal bones can also be placed in the category of long bones of upper extremities after humerous, radius and ulna.Common characteristics are:1. The base (Carpal extremity)2. The body (The Shaft)3. The head (distal extremity)The Base or Carpal extremity articulates with the carpal bones and with the adjoining metacarpal bones.The body is the shaft of the metacarpal bone. (medial area)The head or the Distal extremity articulates with the proximal end of phalanx.So far, it is clear that metacarpal bones are attached with proximal phalanges one side and with carpal bones on the other side, hence it can be concluded that metacarpal bones make the palm.Now I think that the reader might have got his desired answer.Answered by:Ayaz AhmedLecturer, Biomedical Engineering Deptt.SIMS, Indore (MP), IndiaMob: 9425069195
