scapula and clavicle

Question 1

shape of clavicle

Answer 1

S -shaped

Question 2

features of superior surface of clavicle

Answer 2

smooth surface

shaft of clavicle

Question 3

features of inferior surface of clavicle

Answer 3

rough surface

medial 1/3 of clavicle = impression for costoclavicular ligament

middle 1/3 of clavicle = subclavian groove

lateral 1/3 of clavicle = conoid tubercle / trapezoid line

Question 4

facets of clavicle

Answer 4

STERNAL FACET = a triangular surface on the medial end of the clavicle for articulation with the manubrium of the sternum

ACROMIAL FACET = small oval facet on the lateral end of the clavicle for articulation with the clavicular articular facet of the acromion.

Question 5

angles of scapula

Answer 5

superior
lateral
inferior
(acromial)

Question 6

borders of scapula

Answer 6

superior
lateral
medial

Question 7

features of costal surface of scapula

Answer 7

subscapular fossa = concave depression located on the anterior (costal) surface of the scapula bone only.

coracoid process = a small hook-like structure on the lateral edge of the superior anterior portion of the scapula. Pointing laterally forward, it, together with the acromion, stabilizes the shoulder joint.

Question 8

features of posterior surface of scapula

Answer 8

acromion
spine of scapula
infraspinous fossa
supraspinous fossa
deltoid tubercle of scapula

Question 9

facets of scapula

Answer 9

glenoid cavity = a part of the shoulder. It is a shallow articular surface

located on the lateral angle of the scapula

directed laterally and forward and articulates with the head of the humerus

Question 10

costal tuberosity of clavicle

Answer 10

a broad rough surface for the attachment of the costoclavicular ligament.

Question 11

subclavian groove of clavicle

Answer 11

gives attachment to the Subclavius; the coracoclavicular fascia, which splits to enclose the muscle, is attached to the margins of the groove.

Question 12

conoid tubercle of clavicle

Answer 12

prominence on the inferior aspect of the posterior surface of the clavicle that forms one attachment of the conoid ligament.

Question 13

trapezoid line of clavicle

Answer 13

runs forward and laterally, and affords attachment to the trapezoid ligament on inferior surface of clavicle.

Question 14

superior angle of scapula

Answer 14

= covered by the trapezius muscle. This angle is formed by the junction of the superior and medial borders of the scapula.
The superior angle is located at the approximate level of the second thoracic vertebra.

Question 15

lateral angle of scapula

Answer 15

(also known as the head of the scapula)

the thickest part of the scapula.
It is broad and bears the glenoid cavity on its articular surface which is directed forward, laterally and slightly upwards

articulates with the head of the humerus.

Question 16

inferior angle of scapula

Answer 16

located at the lowest point of the scapula

the acute angle formed by junction of the medial and lateral borders of the scapula.

Question 17

acromial angle of scapula

Answer 17

prominent bony point at the junction of the lateral border of acromion and the spine of scapula.

Question 18

superior border of scapula

Answer 18

is concave and extends from the superior angle of the scapula to the coracoid process.
It is the shortest and thinnest of the three borders of the scapula.

Question 19

lateral border of scapula

Answer 19

The lateral border of the scapula is also known as the axillary border of the scapula.
Lateral border of the scapula is thick and presents the infraglenoid tubercle at the upper end (superior to the glenoid cavity, where the scapula articulates with the head of the humerus to form the gleno-humeral joint)

Question 20

medial border of scapula

Answer 20

thin, and extends from the superior angle to the inferior angle of the scapula (and is therefore the longest of the borders).
Is the location of insertion of the levator scapulae, rhomboid minor and rhomboid major muscles
