What does the scapular notch do?
The great scapular notch (or spinoglenoid notch) is a notch which serves to connect the supraspinous fossa and infraspinous fossa. It lies immediately medial to the attachment of the acromion to the lateral angle of the scapular spine.
What goes in the scapular notch?
The suprascapular nerve passes through the notch beneath the superior transverse scapular (suprascapular) ligament, which bridges the notch. The suprascapular artery and vein pass directly over the nerve above the ligament.
Is the suprascapular notch the same as the scapular notch?
The suprascapular notch (or scapular notch) is a notch in the superior border of the scapula, just lateral to the base of the coracoid process. It forms the entrance site into the suprascapular canal.
What runs through the greater scapular notch?
The suprascapular nerve and artery passes through the notch on their course over the scapula.
Where is the superior angle of the scapula?
The superior angle of the scapula, located on the upper part of the scapula, flat to the second rib, is the attachment point of the levator scapula muscle and an important clinical landmark [6].
Where is the superior border of the scapula?
The superior border of the scapula extends from the superior angle to the coracoid process. The coracoid process is a hook-like structure that comes off anteriorly from the lateral superior aspect of the ventral side of the scapula. Like the acromion, it is an attachment point for muscles and ligaments.
What is spinoglenoid notch?
The spinoglenoid notch is located between the base of the spine of scapula and the glenoid process of the scapula that connects the infraspinatus fossa with the supraspinatus fossa, as a passage for the suprascapular nerve and artery, bounded by the inferior transverse scapular ligament (spinoglenoid ligament).
What is the function of the superior angle of the scapula?
The superior angle of the scapula forms the point of insertion of the levator scapula (muscle, pl. levator scapulae) whose functions, or ‘actions’ include a combination of raising the the scapula and / or rotating the head and / or tilting the head to the side.
What attaches to the superior angle of the scapula?
Levator scapulae muscle – they insert into the superior angle and medial border (superior to the spine).
What is superior border?
Description. Of the three borders of the scapula, the superior border is the shortest and thinnest; it is concave, and extends from the medial angle to the base of the coracoid process. At its lateral part is a deep, semicircular notch, the scapular notch, formed partly by the base of the coracoid process.
What nerve goes through the spinoglenoid notch?
Suprascapular nerve entrapment
Suprascapular nerve entrapment most commonly occurs in the confined space of the suprascapular notch or spinoglenoid notch. At the level of the suprascapular notch, the suprascapular nerve contains motor and sensory branches to both the supraspinatus and infraspinatus muscles.
Where is superior scapula angle?
What is superior border of scapula?
What is the superior angle of the scapula?
What is superior angle?
Anatomical Parts Of the three angles, the superior angle (medial angle), formed by the junction of the superior and vertebral borders, is thin, smooth, rounded, inclined somewhat lateralward, and gives attachment to a few fibers of the Levator scapulæ.
