Is the scapula medial or lateral?
The scapula is a thin, flat triangular-shaped bone placed on the postero-lateral aspect of the thoracic cage.
What is lateral rotation of the scapula?
Scapular lateral rotation describes the rotation of the scapula (scapulothoracic joint) such that the glenoid fossa faces upwards – thus it may also be called upward rotation. This motion allows elevation of the humerus as seen in abduction of the arm. It is almost always associated with scapular protraction.
Where is the lateral border of the scapula?
axillary border
The lateral border (axillary border) is the thickest of the three borders of the scapula. It begins above at the lower margin of the glenoid cavity, and inclines obliquely downward and backward to the inferior angle. Immediately below the glenoid cavity is a rough impression, the infraglenoid tuberosity,about 2.5 cm.
What attaches to lateral border of scapula?
Lateral border or margin (Margo lateralis) is the lateral edge of the scapula. The teres minor muscle attaches along this surface, which is also called the axillary border.
Is scapula axial or appendicular?
The appendicular skeleton is everything else. It’s everything that attaches on to the axial skeleton. Think “appendages”. The pelvis, femur, fibula, tibia and all of the foot bones as well as the scapula, clavicle, humerus, radius, ulna and all of the hand bones are classified as appendicular.
What are scapular motions?
The scapula is an important bone in the function of the shoulder joint. It engages in 6 types of motion, which allow for full-functional upper extremity movement including protraction, retraction, elevation, depression, upward rotation, and downward rotation.
How do you side the scapula?
Right vs. Left–In order to determine if a scapula is right or left, orient it so the glenoid cavity (articulating surface) faces laterally (outward) and the spine is posterior (toward back) and superior (upper). The coracoid process should be anterior and superior.
What is another name for the lateral border of the scapula?
The axillary border (or “lateral border”) is the thickest of the three. It begins above at the lower margin of the glenoid cavity, and inclines obliquely downward and backward to the inferior angle. It is referred to as the caudal border in animals.
