Forelimb
Upper Forelimb
A muscle that contains three heads, hence the name tricep, and covers most of the surface of the upper forelimb. The Triceps Brachii helps to extend the elbow by opposing to the Biceps Brachii, which lies on the inside of the upper forelimb.
To expose the Tricep, skin the forelimb and it should be found on the posterior side. |
Triceps Brachii
The Biceps Brachii lies on the opposite side of the upper forelimb than the Triceps. It works opposite to the Tricep as one flexes while the other extends.
To find the Biceps Brachii, skin the forelimb and it should be located on the medial side, opposite the Tricep. |

Lower Forelimb
Extensor Carpi Ulnaris (5th)
|
The Brachioradialis is the most anterior of the five muscles seen here. Initially it may look like one muscle combined with the Extensor Carpi Radialis, but don't be fooled. The brachioradialis assists with the flexing of the elbow.
The other four muscles are also narrow bands that all originate in the lower or distal portion of the humerus. They are extensors of the digits and the front feet, at what would be the wrist joint in a human. To find these muscles, skin the forelimb with extreme caution. They are all very thin and could be torn easily if you are not paying attention. All five muscles are located on the lateral side of the forearm. |
