Like any triangle, the scapula consists of three borders: superior, lateral and medial. The superior border is the shortest and thinnest border of the three. The medial border is a thin border and runs parallel to the vertebral column and is therefore often called the vertebral border.
Lateral angle: where the superior border converges with the lateral border. Superior angle: Where the superior border also meets with the medial border. Inferior angle: Where the medial and lateral borders meet.
The superior angle (medial angle) of scapula is the sharp area of the bone where its medial and superior borders meet. It is located superficial to the second rib and is one of the three angles of the scapula, the other two being the inferior and lateral angles.
Superior Angle is covered by trapezius. Inferior angle is covered by the latissimus dorsi. It moves forwards round the chest, when the arm is abducted. Palpation of the inferior angle provides a convenient method for following the movement of the scapula during arm motion.
Definition. 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.
Angles of the Scapula. Superior Angle: The junction between the superior and medial borders. Inferior Angle: Where the medial and lateral borders converge; important in movements of the scapula. Lateral Angle: The thickest part of the scapula, housing the glenoid cavity, which articulates with the humerus to form the shoulder joint.
Scapula has three angles, lateral, superior and inferior. The superior and inferior angles of the scapula are unremarkable. The lateral angle features a region called the glenoid process of scapula.
The superior angle of the scapula is the uppermost point where the medial (vertebral) border meets the superior (upper) border of the scapula, or shoulder blade. It serves as an important landmark for muscle attachment and movement.
Overall, the scapula has two surfaces and three margins that meet at three angles. Additionally, it presents three processes (acromion, scapular spine, and coracoid process). Surfaces of scapula. The scapula has two surfaces - anterior (ventral or costal) surface and posterior (dorsal) surface.
