In two hour-long episodes, presenter George McGavin (Glasgow University) delves beneath the skin to expose the anatomy of the human hand and foot. The series sheds light on the various functions of the hand and foot by identifying the muscles, tendons and ligaments responsible for movement, and how the human anatomy compares with that of other animals.
Episode 1: Hand The dissection of the donor arm begins in the forearm to expose the muscles which give power to the hand for gripping and the tendons which attach each muscle to the bones in the fingers. The surgeon demonstrates how the tendons motion in the hand by tugging on the tendons to cur the fingers. The structure of the hand can be changed with heavy use – the X-ray of a frequent rock climber shows that the cortical bone (the hard outer layer of the skeleton) is thicker than in a non-climber the tendons and pulleys are also thicker, this allows their hands to maintain a firmer grip.
