2. Large extensor of the fore-arm. 



3. Short extensor of the fore- arm. 



4. Middle extensor of the fore-arm. 



5. Small extensor of the fore-arm, or anconeus muscle. 



6. Oblique flexor of the metacarpus. 



7. Deep flexor of the phalanges, or perforans. 



b. By its body, to the 



1. Short flexor of the fore-arm, or anterior brachial muscle. 



2. Lateral extensor of the phalanges. 



D. BONES OF THE CARPUS. 



Supercarpal Bone. 



The supercarpal bone, the only bone of the carpus which has muscular 

 attachments, gives insertion to two muscles : 



1. External flexor of the metacarpus, or posterior ulnar. 



2. Oblique flexor of the metacarpus. 



E. BONES OF THE METACARPUS. 



I. Principal Metacarpal. 



The principal metacarpal gives insertion to a single muscle : 

 By its superior extremity, to the 



Anterior extensor of the metacarpus. 



II. External Rudimentary Metacarpal. 

 This gives insertion to a single muscle : 



External flexor of the metacarpus, or posterior ulnar. 



III. Internal Rudimentary Metacarpal. 

 This gives insertion to two muscles : 



1. Oblique extensor of the metacarpus. 



2, Internal flexor of the metacarpus, or groat palmar muscle. 



F. BONES OF THE DIGITAL REGION. 



I. First Phalanx. 

 This gives insertion to two muscles : 



1. Anterior extensor of the phalanges. 



2. Lateral extensor of the phalanges. 



II. Second Phalanx. 

 This gives insertion to two muscles : 



1. Anterior extensor of the phalanges. 



2. Superficial flexor of the phalanges. 



III. Third Phalanx. 



The third phalanx, or os pedis, gives insertion to two muscles :
