What is the lateral extension of the spine of the scapula?
What is the lateral extension of the spine of the scapula?
The acromion process is the lateral extension of the spine of scapula.
What is the most lateral part of the scapula?
glenoid fossa
Laterally is the glenoid fossa. Superiorly is the acromion that is continuous with the scapular spine and arcs anteriorly over the humeral head. The suprascapular notch lies immediately medial to the base of the coracoid process. The spinoglenoid notch lies posteriorly behind the neck.
What attaches to the scapular spine?
The trapezius is attached to the superior lip, and a rough tubercle is generally seen on that portion of the spine which receives the tendon of insertion of the lower part of this muscle. The deltoideus is attached to the whole length of the inferior lip.
What attaches to the vertebral border of the scapula?
The serratus anterior muscle surrounds the superior and inferior angles of the scapula and is thus attached to both the surfaces of the bone at these sites.
Where is the spine of the scapula?
The spine of the scapula or scapular spine is a prominent plate of bone, which crosses obliquely the medial four-fifths of the scapula at its upper part, and separates the supra- from the infraspinatous fossa.
Which edge of the scapula is closest to the vertebrae?
Which part of the scapula is closest to the vertebral column? The scapula is a triangle-shaped bone. The three sides are the superior border, the medial border, and the lateral border. The medial border, sometimes called the vertebral border, is closest to the vertebral column.
What spinal level is spine of scapula?
One such landmark is the inferior angle of the scapula (IAS), which is said to correlate with the T7, T8, or T9 spinous process or spinal level, depending on the source. Gray’s Anatomy indicates that the IAS corresponds to the level of the ninth rib, which attaches to the spine at the T8–9 interspace.
