LabelAnswer
A View? and which scapula is it (right or left)Costal Surface and left
B View? and which scapula is it (right or left)Dorsal Surface or left scapula
CInferior Angle, this can be the origin of a few fibres of the Latissiumus Dorsi
DSuperior Angle (somtimes called medial angle), covered by the Trapezius
E Referring to what angle? Acromial (lateral)Angle
FSuperior border - it is the shortest and thinnest; it is concave, and extends from the Superior angle to the base of the coracoid process. It is also the origin of the Omohyoid Muscle
GThe 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 the site of insertion for Teres Minor (superior), and Teres Major (inferior)
HThe vertebral border (or "medial border") is the longest of the three, and extends from the medial to the inferior angle.It the site of insertion for various muscles - Serratus Anterior, Rhomboid Major, Rhomboid Minor, Levator Scapulae
I What is this, and what three muscles are attached here? Coracoid Process, it is the site of origin for the Coracobrachialis and the short head of the Biceps Brachii. And it is the site of insertion for the pectoralis MinorPectoralis Major and Biceps Brachii.
JThe acromion Process (or can just call the acromion). It forms the summit of the shoulder, and is a large, somewhat triangular or oblong process, flattened from behind forward, projecting at first lateral, and then curving forward and upward, so as to overhang the glenoid cavity. It articulates with the clavicle to form the acromioclavicular joint.
KSpine, Here is insertion of Trapezius.
LSupraspinous Fossa, is the top devision of the dorsal surface
MInfraspinous fossa. The medial two-thirds of the fossa give origin to the Infraspinatus;
NSubscapular fossa, this is the origin of the Subscapularis (muscle).
OSpine, Here is insertion of Trapezius.

Question Answer
Which Parts of the scapular can you feel on yourself?on most people you can palpate the spine, acromian coracoid process, the inferior angle, and much of the medial border of the scapula
Much of the Scapular is very thin yet it is rarely fractured why?It is protected by muscle, it is floating, that is it is fairly mobile, and the overall structure of the spine of scapular is a strong stucture.
