Ulna Bone Labeled. Fine lets identify the different segments and bones from the dog skeletal system. In other words the ulna can be found between the proximal carpal row and the upper arm bone humerus running parallel to the other lower arm bone radius 3 5.
In the standard anatomical position with palms faced anteriorly the ulna lies medially but the radius is lateral. The radius and the ulna constitute as the bones of the forearm. The segments and bones of the thoracic limb scapula humerus radius ulna carpal metacarpal and phalanx.
In the classical anatomical position the radius is found laterally while the ulna is the medial of the two bones.
Identify the structure labeled as 1. The ulna is is involved in the wrist and the elbow joint with the following articulations. Label the structures of the bones. The carpal bones help form the wrist where they join with each other and with the radius and ulna of the forearm.
