The superior transverse ligament (transverse or suprascapular ligament
) converts the
suprascapular notch
The suprascapular notch (or ''scapular notch'') is a notch in the superior border of the scapula, just medial to the base of the coracoid process. It forms the entrance site into the suprascapular canal.
Structure
This notch is converted into ...
into a foramen or opening.
It is a thin and flat
fascicle
Fascicle or ''fasciculus'' may refer to:
Anatomy and histology
* Muscle fascicle, a bundle of skeletal muscle fibers
* Nerve fascicle, a bundle of axons (nerve fibers)
** Superior longitudinal fasciculus
*** Arcuate fasciculus
** Gracile fas ...
, narrower at the middle than at the extremities, attached by one end to the base of the
coracoid process
The coracoid process (from Greek κόραξ, raven) is a small hook-like structure on the lateral edge of the superior anterior portion of the scapula (hence: coracoid, or "like a raven's beak"). Pointing laterally forward, it, together with the ...
and by the other to the medial end of the scapular notch.
The
suprascapular nerve
The suprascapular nerve is a nerve that branches from the upper trunk of the brachial plexus. It is responsible for the innervation of two of the muscles that originate from the scapula, namely the supraspinatus muscle, supraspinatus and infraspina ...
always runs through the foramen; while the suprascapular vessels cross over the ligament in most of the cases.
The suprascapular ligament can become completely or partially
ossified
Ossification (also called osteogenesis or bone mineralization) in bone remodeling is the process of laying down new bone material by Cell (biology), cells named osteoblasts. It is synonymous with bone tissue formation. There are two processes ...
. The ligament also been found to split forming doubled space within the suprascapular notch.
