Metacarpal bones

The video tutorial by Joao from Kenhub covers the anatomy of the metacarpal bones in the hand. It begins with an introduction to the metacarpals, their location between the carpal bones and phalanges, and the orientation of the hand. The tutorial then delves into the structure of the metacarpals, highlighting the base, shaft, and head. It also discusses the articulations of each metacarpal with adjacent bones, including the trapezium, trapezoid, capitate, and hamate. The video concludes with suggestions for further learning through Kenhub's resources.
