Answer 2

true

Question 3

clavicle: Blunt, thickened medial end that articulates with the sternum via a compound synovial joint (with articular disc).

Answer 3

sternal extremity

Question 4

Answer 5

Conoid tubercle

Question 6

List all attachments of clavicle: (ligaments, muscle origins, muscle insertions, articulations)

Answer 6

ligaments:
1. coracoclavicular ligament (trapezoid & conoid)
2. costoclavicular ligament
muscle origins:
1. pecs major
2. sternocleidomastoid
3. deltoid
muscle insertions:
1. trapezius
2. subclavius

Question 7

Most commonly fractured bone due to trauma; what are main causes?

Answer 7

clavicle; due to trauma like fall or outstretched hand

Question 8

weakest point of clavicle

Answer 8

junction of the middle and outer thirds

Question 9

Large, flat, triangular bone lying on the posterior chest wall (ribs 2–7).

Answer 9

scapula

Question 10

Lies horizontally between the sternum and scapula, connecting the upper limb to the thorax.

S-shaped, resembling an old-style key, and easily palpable.

Answer 10

clavicle

Question 12

what angle of the scapula is palpable?

Answer 12

inferior angle

Question 13

list the following: (scapula)
3 borders
3 angles
2 surfaces
3 processes
3 fossae

Answer 13

3 Borders - Superior, medial (vertebral), and lateral (axillary).
3 Angles - Superior, inferior (level of rib 7), and lateral (thick, includes glenoid cavity for humerus articulation).
2 Surfaces - dorsal and costal
3 Processes - Spine, acromion, coracoid.
3 Fossae - Supraspinous (above the spine), infraspinous (below the spine), subscapular (anterior).

Question 14

what is the arrangement of structures in the suprascapular notch?

Answer 14

superior to inferior:
(army over the bridge, navy under the bridge)
1. suprascapular artery
2. superior transverse scapular ligament
3. suprascapular nerve

Question 15

Fibrocartilage ring that deepens and broadens the cavity.

Answer 15

glenoid labrum

Question 16

Elevation at the apex of the glenoid cavity.

Answer 16

Supraglenoid Tubercle:

Question 17

Scapula: Large triangular ridge dividing the posterior surface into two regions

Answer 17

spine of the scapula

Question 18

connects the supraspinous and infraspinous fossae; allows passage for the suprascapular nerve and vessels

Answer 18

spinoglenoid fossa

Question 19

tip of the shoulder

Answer 19

acromion p.

Question 20

Thick, beak-like projection from the junction of the neck and superior border.
Palpable through the anterior deltoid muscle, beneath the clavicle.

Answer 20

coracoid p.
