supraspinous fossa of the scapula

Answer 4

a fossa located above the spine

Question 5

the acromion (process) of the scapula

Answer 5

o Is on the superior side pointing laterally. Is a large projection articulating with the clavicle, goes on to form the posterior section of the spine.

Question 6

the coracoid process of the scapula

Answer 6

a projection on the scapula that looks like a finger

Question 7

the glenoid cavity of the scapula

Answer 7

where the head of the humerus articulates laterally

Question 8

the sternal end of the clavicle

Answer 8

o Looks blunt and is cone shaped. Comes into contact with the sternum. Is known as the enlarged, quadrangular part of the clavicle that articulates with the sternum and first costal cartilage

Question 9

the acromial end of the clavicle

Answer 9

o The flattened, lateral part of the clavicle bone that articulates with the acromion of the scapula to form the acromioclavicular joint.

Question 10

the conoid tubercle of the clavicle

Answer 10

o Is a bony prominence on the clavicle that serves as an attachment site for the conoid ligament. Is form the inferior side and is a projection near the acromial end.

Question 11

the head of the humerus

Answer 11

o The nice round articulate surface on the posterior end, articulates and forms the shoulder joint.
 Faces medially

Question 12

the greater tubercle of the humerus

Answer 12

o The projection on the head of the lateral proximal side. Is the attachment for the rotator cuff

Question 13

the lesser tubercle of the humerus

Answer 13

o A smaller projection on the inner portion and is an attachment point for the rotator cuff

Question 14

the intertubercular groove of the humerus

Answer 14

the groove between the lesser and greater tubercle

Question 15

anatomical neck versus surgical neck

Answer 15

o Anatomical – matches the definition. The point of the bone right where you get the narrowing form the head.
o Surgical – because this is where the bone functionally is thinned. A very common spot for fractures

Question 16

the deltoid tuberosity of the humerus

Answer 16

o The deltoid muscle attaches to this. Is the rough and bumpy portion of the shaft.

Question 17

the capitulum of the humerus

Answer 17

o The ball shape on the distal side to articulate with the radius to help form the elbow joint

Question 18

the trochlea of the humerus

Answer 18

o The forming of the joint between the humerus and the ulna. In the middle and looks like a spool, helps to move the elbow joint

Question 19

the coronoid fossa of the humerus

Answer 19

a small depression found superior to the trochlea of the humerus

Question 20

the radial fossa of the humerus

Answer 20

a protuberance above or on the condyle

Question 21

lateral epicondyle

Answer 21

o Lateral epicondyle on lateral side
 Is a bony bump on the outside of the elbow, point of attachment for the forearm muscles and the ligaments

Question 22

medial epicondyle

Answer 22

o Medial (toward the shoulder) medial condyle
 Is a round/prominent part of the bone at the end of the upper arm bone inside the elbow

Question 23

olecranon fossa of the humerus

Answer 23

o A deep large indentation on the posterior side. Is an articulation for the olecranon on the ulna

Question 24

the head of the radius

Answer 24

the rounded proximal end

Question 25

the radial tuberosity of the radius

Answer 25

o Is an attachment point for the bicep brachia. Named for the bone that it is on

Question 26

the ulnar notch of the radius

Answer 26

o An indentation on the medial side of the distal, radius that lets the ulna articulate
 Named because the ulna sits on it

Question 27

the styloid process of the radius

Answer 27

o A sharp projection of bone that comes down on the distal end.
 Sits on the side of the wrist and helps to stabilize the wrist.

Question 28

the olecranon process of the ulna

Answer 28

o The point part of the elbow, is directly above the trochlear notch

Question 29

the coronoid process of the ulna

Answer 29

o A lower notch below the olecranon, is a crown shaped indent. On the underside of the trochlear notch

Question 30

the trochlear notch of the ulna

Answer 30

a moon shaped notch in the bone, is an articulation with the distal radius

Question 31

radial notch for the ulna

Answer 31

a notch on the side of the ulna that articulates with the head of the radius

Question 32

head of the ulna

Answer 32

o Is on the distal end, by the styloid process

Question 33

styloid process of the ulna

Answer 33

o At the bottom which helps stabilize the wrist.

Question 34

scaphoid carpal bone

Answer 34

proximal under the thumb

Question 35

lunate carpal bone

Answer 35

moon shaped more medial than the scaphoid

Question 36

pisiform carpal

Answer 36

the last in the proximal row, is the bump we can feel on our wrist by the pinky
