Anatomical terminology

The superior transverse ligament (transverse or suprascapular ligament [1] ) converts the suprascapular notch into a foramen or opening.

It is a thin and flat fascicle, narrower at the middle than at the extremities, attached by one end to the base of the coracoid process and by the other to the medial end of the scapular notch.

The suprascapular nerve always runs through the foramen; while the suprascapular vessels cross over the ligament in most of the cases. [2] [3]

The suprascapular ligament can become completely or partially ossified. The ligament also been found to split forming doubled space within the suprascapular notch. [4]

<span class="mw-page-title-main">Acromion</span> Bony process on the scapula (shoulder blade)

In human anatomy, the acromion is a bony process on the scapula. Together with the coracoid process, it extends laterally over the shoulder joint. The acromion is a continuation of the scapular spine, and hooks over anteriorly. It articulates with the clavicle to form the acromioclavicular joint.

<span class="mw-page-title-main">Scapula</span> Bone that connects the humerus (upper arm bone) with the clavicle (collar bone)

The scapula, also known as the shoulder blade, is the bone that connects the humerus with the clavicle. Like their connected bones, the scapulae are paired, with each scapula on either side of the body being roughly a mirror image of the other. The name derives from the Classical Latin word for trowel or small shovel, which it was thought to resemble.

<span class="mw-page-title-main">Coracoid process</span> Small hook-like structure on the lateral edge of the superior anterior portion of the scapula

The coracoid process is a small hook-like structure on the lateral edge of the superior anterior portion of the scapula. Pointing laterally forward, it, together with the acromion, serves to stabilize the shoulder joint. It is palpable in the deltopectoral groove between the deltoid and pectoralis major muscles.

The suprascapular nerve is a mixed nerve that branches from the upper trunk of the brachial plexus. It is derived from the ventral rami of cervical nerves C5-C6. It provides motor innervation to the supraspinatus muscle, and the infraspinatus muscle.

The posterior clinoid processes are the tubercles of the sphenoid bone situated at the superior angles of the dorsum sellæ which represents the posterior boundary of the sella turcica. They vary considerably in size and form. The posterior clinoid processes deepen the sella turcica, and give attachment to the tentorium cerebelli, and the dura forming the floor of the hypophyseal fossa.

<span class="mw-page-title-main">Glenoid fossa</span> Part of the shoulder

The glenoid fossa of the scapula or the glenoid cavity is a bone part of the shoulder. The word glenoid is pronounced or and is from Greek: gléne, "socket", reflecting the shoulder joint's ball-and-socket form. It is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula. It is directed laterally and forward and articulates with the head of the humerus; it is broader below than above and its vertical diameter is the longest.

<span class="mw-page-title-main">Suprascapular notch</span> Groove in the superior border of the scapula, for the suprascapular nerve to pass through

The suprascapular notch is a notch in the superior border of the scapula, just medial to the base of the coracoid process. It is converted into the suprascapular canal by the suprascapular ligament.

The suprascapular vein is a vein running above the scapula. It drains into the external jugular vein. It drains the posterior region around the scapula.

The pterygospinous ligament stretches from the upper part of the posterior border of the lateral pterygoid plate to the spinous process of the sphenoid.

<span class="mw-page-title-main">Suprascapular canal</span> Anatomical passage between two openings found on the upper dorsal aspect of the shoulder

The suprascapular canal is an anatomical passage between two openings found on the upper dorsal aspect of the shoulder. It is found bilaterally running on superior-lateral aspect of the dorsal surface of the scapula underneath the supraspinatus muscle.

Transforaminal ligaments are inconstant ligaments that extend through an intervertebral foramen. They are thought to protect the adjacent spinal nerve and vessels. The ligaments are not widely known and were once considered anomalous; there are no widely accepted criteria for their identification and classification. They were once postulated to be a cause of spinal nerve entrapment, however, at present, their role in the radicular pain has is unclear.
