[The laterocranial fascia structures in the upper and forearm and the differences in the insertion of the M. biceps brachii in domestic mammals].
Abstract: The laterocranial fascia of the upper arm and forearm, as well as aponeurotic relationships of the Musculus biceps brachii were investigated on each of ten forelimbs from horses, cattle and swine. Ten canine biceps were also investigated. Equine and bovine fascia contain elastic components. An as-yet undescribed ligament-like aponeuroses of the laterocranial forearm fascia to the Fossa radialis humeri was seen in all three species studied. The laterocranial fascia of the upper and forearm form a common passage for the Musculi brachialis et extensor carpi radialis. In the case of the horse, the ulnar aponeurotic tendon of the biceps muscle crosses below the Ligamentum collaterale cubiti medialis. In cattle, on the other hand, it runs between the two branches of the collateral ligament, to attach on the olecranon. This portion of the equine tendon protrudes into the joint. It has connective tissue character in young animals, but becomes fibrocartilaginous in older horses. The radial aponeuroses of the canine biceps exhibits two branches. A situation similar to that seen for the ulnar aponeuroses of the equine Musculus biceps brachii is observed on the inside surface of the porcine Ligamentum cubiti mediale, in which a wedge of connective tissue protrudes into the joint, taking on fibrocartilaginous character in older animals.

This research paper uncovers new insights about the detailed structure of the laterocranial fascia (a sheet-like connective tissue) in the upper arms and forearms of various domestic mammals; it also focuses on the differences in the attachment of the biceps brachii muscle among these animals.
Research Methodology
- The study used 10 forelimbs from horses, cattle, and pigs, as well as 10 canine biceps for a comparative analysis.
- The research targeted an investigation into the unique elastic components in the laterocranial fascia of horses and cattle.
New Findings
- The researchers noted a previously unidentified ligament-like extension of the laterocranial forearm fascia linking to the Fossa radialis humeri (a depression in the humerus bone) in all three species studied.
- The laterocranial fascia in the upper arm and forearm were seen to form a joint channel for the brachialis muscle (which bends the elbow) and the extensor carpi radialis muscle (which helps in bending the wrist).
Differences in Biceps Brachii Placement
- In horses, the ulnar aponeurotic tendon (a type of connective tissue) of the biceps muscle passes beneath the medial collateral ligament of the elbow joint.
- In cattle, it is positioned between the two extensions of the collateral ligament, attaching itself to the olecranon (the pointed bone at the elbow).
- In both these cases, a part of the tendon sticks out into the joint and develops from general connective tissue in young individuals to fibrocartilage (containing both collagen fibers and cartilage cells) in older animals.
Biceps in Canines and Pigs
- The radial aponeurosis (broad, flat tendon) of the canine biceps splits into two branches.
- The connective tissue structure similar to the ulnar aponeurosis of the horse biceps brachii occurs on the inner surface of the pig’s medial elbow ligament, extending like a wedge into the joint and turning fibrocartilaginous in older pigs.
