Carpal bones

The video tutorial by Wang from Kenhub provides an in-depth exploration of the carpal bones in the wrist. It covers the orientation and location of these bones, dividing them into proximal and distal rows. Each bone is discussed in detail, including the scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, and hamate, along with their articulations and unique features. The tutorial also offers mnemonics to aid in memorization and concludes with resources for further learning.
