What rib is the spine of the scapula indicative of?
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….

What muscle is superior to the scapular spine?
Levator scapulae muscle – they insert into the superior angle and medial border (superior to the spine).
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].
What are the three borders of spine of scapula?
The scapula has three angles (superior/medial, lateral, inferior), three borders (medial, lateral/axillary, and superior), and two surfaces (ventral and dorsal). The scapula has three processes: the acromion, the spine, and the coracoid process.
How is winged scapula diagnosed?
Scapular winging is diagnosed easily by visible inspection of the scapula, but its etiology is often more illusive. Medial winging due to serratus anterior paralysis is accentuated when patients are asked to forward flex their arms to the horizontal and push on a wall in a push-up motion.
Will the superior region elevate or depress the scapula?
Upper fibers elevate the scapula and rotate it during abduction of the arm (90 to 180 degrees) Middle fibers retract the scapula. Lower fibers pull the scapula inferiorly.
Which muscle is located between the rib cage and the scapula?
The serratus anterior originates via eight muscular “slips” that attach to the side of your ribs. It then courses around the side of your rib cage and underneath your scapula. There, it inserts along the medial border of your scapula.
Where is the acromion of the scapula?
shoulder
In human anatomy, the acromion (from Greek: akros, “highest”, ōmos, “shoulder”, plural: acromia) is a bony process on the scapula (shoulder blade). 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.
Which border of the scapula is closest to the spine?
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.
Is a winged scapula serious?
Scapular winging is a rare, but potentially debilitating condition that can affect the ability to lift, pull, and push heavy objects, as well as to perform daily activities of living, such as brushing one’s hair and teeth and carrying grocery bags [1].
What is the spine of the scapula?
The spine of the scapula is a thick, prominent plate of bone that crosses obliquely the medial 4/5 of the posterior surface of the scapula. Anterior Border: This border is faced anteriorly towards the posterior surface of the bone, and is attached to it. Subsequently, question is, what muscles insert on the spine of the scapula? Function
What is the scientific name for the scapular bone?
Anatomical terms of bone. [edit on Wikidata] 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.
What is the lateral border of the scapula?
The lateral border, or base, the shortest of the three, is slightly concave; its edge, thick and round, is continuous above with the under surface of the acromion, below with the neck of the scapula. It forms the medial boundary of the great scapular notch, which serves to connect the supra- and infraspinatous fossae.
What is the superior angle of the scapula?
There are also three angles to the scapula. The superior border meets the lateral border at the lateral angle and with the medial border at the superior angle. The third angle is the inferior angle where the medial and lateral borders meet. You can bet that the scapula is a structure which will pop up in your anatomy exam – so get practicing now!
