The medial palmar nerve then divides branches from the ulnar nerve proximal to the elbow to into a medial palmar digital nerve and a dorsal branch. There are no true ligaments in the shoulder joint. We find the horse distal forelimb shares features with that of an early horse embryo. Several forelimb muscles of the fox squirrel show significantly higher mean contraction times than do the homologous muscles of the prairie dog.
