Sternum, Rib, and Clavicle

Question 1

Sternum

Answer 1

the breastbone

Question 2

manubrium

Answer 2

the uppermost segment of the sternum

Question 3

clavicular notch

Answer 3

a notch on each side of the upper part of the manubrium that is the site of articulation with a clavicle.

Question 4

sternum body

Answer 4

the middle and largest portion of the sternum

Question 5

clavicle

Answer 5

collarbone

Question 6

xiphoid process

Answer 6

the cartilaginous section at the lower end of the sternum, which is not attached to any ribs and gradually ossifies during adult life

Question 7

Rib head

Answer 7

see picture

Question 8

Rib Shaft/body

Answer 8

the portion that extends laterally, anteriorly, and then medially from the tubercle

Question 9

Rib tubercle

Answer 9

an oval facet on the inferomedial part of the tubercle of a rib for articulation with a facet on the transverse process of a vertebra

Question 10

costal cartilage

Answer 10

bars of hyaline cartilage which serve to prolong the ribs forward and contribute to the elasticity of the walls of the thorax found on the anterior of the rib

Question 11

sternal end (clavicle)

Answer 11

the enlarged medial end of the clavicle that articulates with the manubrium sterni

Question 12

acromial end (clavicle)

Answer 12

the flattened lateral end of the clavicle that articulates with the acromion and is anchored to the coracoid process by the conoid and trapezoid ligaments

Question 13

Scapula

Answer 13

Shoulder blade

Question 14

vertebral (medial) border (Scapula)

Answer 14

the longest of the three borders, and extends from the superior to the inferior angle

Question 15

axillary (Lateral) border

Answer 15

the edge of the scapula extending from the glenoid fossa to the inferior angle

Question 16

acromion process

Answer 16

is a bony process on the scapula (shoulder blade). Together with the coracoid process it extends laterally over the shoulder joint

Question 17

coracoid process

Answer 17

a short projection from the shoulder blade in mammals, to which part of the biceps is attached

Question 18

inferior angle (scapula)

Answer 18

formed by the union of the medial and lateral border of the scapula and is the lowest part of the scapula. It is thick and rough and its posterior (or back) surface affords attachment to the teres major and frequently to a few fibers of the latissimus dorsi muscle

Question 19

superior angle (scapula)

Answer 19

formed by the junction of the superior and medial borders of the scapula

Question 20

glenoid fossa (cavity) scapula

Answer 20

a shallow pyriform, articular surface, which is located on the lateral angle of the scapula

Question 21

supraglenoid tubercle

Answer 21

a region of the scapula from which the long head of the biceps brachii muscle originates

Question 22

scapular spine

Answer 22

a prominent plate of bone, which crosses obliquely the medial four-fifths of the scapula at its upper part, and separates the supra- from the infraspinatous fossa

Question 23

infraspinous fossa

Answer 23

This extensive surface covers most of the inferior two-thirds of the dorsal scapula. It is triangular, with its base merging with the spine superiorly

Question 24

supraspinous fossa

Answer 24

The ditch-like concavity above the spine of the scapula. This comprises approximately the upper third of the dorsal surface of the scapula

Question 25

Subscapular fossa

Answer 25

the extremely shallow concavity on the anterior or ventral (therefore, sub) surface of the scapula

Question 26

scapular notch

Answer 26

a notch in the superior border of the scapula, just medial to the base of the coracoid process
