Fig. 103. Transverse Section through Carpus. 



Frozen section viewed from the Fingers. The second row of Carpal Bones and 

 the Styloid Process of the p'd Metacarpal Bone have been sawn through. 



On the back of the hand the Extensor Tendons, on the outer side the 

 Extensor Ossis Metacarpi and the Extensor Primi Internodii Pollicis, in the palm 

 of the hand the Flexor Tendons are shewn in their relations to each other and 

 to the Bones of the Hand. 



The Concavity of the Carpus with the tunnel completed by the Anterior 

 Annular Ligament are well shewn. 



Note: Radial Artery; Ulnar Artery, and Nerve. The Median Nerve 

 becoming more superficial at the wrist, lies in close approximation to the Flexor 

 Sheath, and directly under the Palmar Fascia. 



(Vide Figs. 98 and loi.)

Frozen Section. Left Hand, seen from tlie fingers. 



The Flexor and Extensor Tendons have diverged towards either the 

 inner (ulnar) or outer (radial) side. The median nerve has divided into many 

 branches. The fleshy muscles of the Thenar and Hypothenar Eminences are 

 evident. The Radial and Ulnar Arteries have divided so that the smaller 

 branches of the Radial, with the exception of the Princeps PoUicis artery, are 

 scarcely visible ; the branches of the Ulnar Artery are readily found accompanying 

 the nerves on the Palmar aspect near the 4th Metacarpal Bone. 



The Palmar Fascia which bridges over the space between the Thenar 

 and Hypothenar Eminences is of great practical importance, because the skin is 

 bound firmly to it so that suppuration deep to the fascia, i. e. around the Tendons 

 or their sheath, becomes pent up, and deep incisions become necessary for the 

 evacuation of the pus. 



The concavity of the hand is well shewn. (Cf. Foot.)
