Medial
Clavicle
The scapulae are widely separated in the:

Three
Lying on the superoposterior thorax between the ____ and _____ ribs, the ______ border of the scapula runs _______ with the vertebral column.
Second and seventh
Medial
Parallel
The body of the scapula bone is ____ from top to bottom for greater strength, and its surfaces serve as the attachment sites of numerous ______.
Arched
Muscles
The flat aspect of the bone lies at approximately a _______- to ______-degree angle in relation to the anatomic position.
45 to 60
The costal (anterior) surface of the scapula is slightly concave and contains the____ fossa:
It is filled almost entirely by the attachment of the____muscle:
Subscapular Fossa
Subscapularis Muscle
The anterior serratus muscle attaches to the medial border of the costal surface from the:
Superior angle to the inferior angle.
The dorsal (posterior) surface is divided into two portions by a:
Prominent spinous process
The _____ of ______ arises at the superior third of the medial border from a smooth, triangular area and runs obliquely superior to end in a flattened, ovoid projection called the ______.
crest of spine
Acromion
The area above the spine is called the _______ fossa and gives origin to the ___________ muscle.
Supraspinous Fossa
Supraspinatus muscle
The infraspinatus muscle arises from the portion below the spine, which is called the:
Infraspinous fossa
The teres minor muscle arises from the superior two-thirds of the ______ border of the _____ surface:
Lateral
Dorsal
Teres major muscle arises from the ____ third and the ____ angle.
Distal
Inferior
The dorsal surface of the medial border affords attachment of the levator muscles of the______, ______ _____ muscle, and the _____ _____ muscle.
Scapulae
Greater rhomboid muscle
Lesser rhomboid muscle
The superior border extends from the _____ angle to the ______ ______:
Superior
Coracoid process
The superior border has a deep depression on its lateral end called the:
Scapular notch
The medial border extends from the _____ to the ______ angles:
Superior
Inferior
The lateral border extends from the_____ cavity to the _____ angle:
Glenoid cavity
Inferior Angle
The superior angle is formed by the junction of the _____ and _____ borders:
Superior
Medial
The inferior angle is formed by the junction of the ______ (vertebral) and ______ borders:
Medial
Lateral
The inferior angle lies over the ____ ____:
Seventh Rib (7th)
The lateral angle is the _______ part of the body of the Scapula:
Thickest part
The lateral angle of the scapula ends in a shallow, oval depression called the:
Glenoid cavity
The constricted region around the glenoid cavity is called the _____ of the scapula:
Neck
The coracoid process arises from a thick base that extends from the _____ notch to the superior portion of the ____ of the scapula
scapular
neck
The coracoid process first projects anteriorly and medially and then curves on itself to project ______:
Laterally
The coracoid process can be palpated just distal and slightly medial to the:
Acromioclavicular AC Articulation
The acromion, coracoid process, superior angle, and inferior angle are common positioning landmarks for:
Shoulder radiography
