The arm

Question 1

Rotated, superior end of humerus that articulates with the glenoid fossa. Faces medially

Answer 1

Humeral head

Question 2

Attachment point on humerus for rotator cuff muscles, lateral surface of humerus

Answer 2

Greater tubercle

Question 3

Attachment point for subscapularis muscle which rotates the arm medially, humerus

Answer 3

Lesser tubercle

Question 4

Groove between humerus tubercles, houses the tendon that connects to biceps muscles

Answer 4

Inter tubercular sulcus

Question 5

Rough, raised ridge of bone of the anterior humerus mid shaft that serves as a point of attachment for the deltoid muscle

Answer 5

Deltoid tuberosity

Question 6

Spool shaped distal end of humerus, articulates with ulna, flared ends and narrow in middle

Answer 6

Trochlea

Question 7

Medial, distal projection of humerus. Swoops towards the middle

Answer 7

Medial epicondyle

Question 8

Lateral, distal projection of humerus, not as pronounced

Answer 8

Lateral epicondyle

Question 9

Smooth rounded area on distal anterior surface that articulates with the head of radius. Lateral and distal, rounded, humerus

Answer 9

Capitulum

Question 10

Large hollow on anterior, distal end of humerus, received the ulna during flexion. Concave surface on the anterior distal end that accommodates the ulna as it slides into the fossa

Answer 10

Coronoid fossa

Question 11

Large hollow on distal, posterior surface of humerus. Articulates with ulna during extension. Hollow, larger than coronoid.

Answer 11

Olecranon fossa

Question 12

Most proximal part of ulna, massive, blunt process. Triceps muscle attached here. Proximal and posterior

Answer 12

Olecranon process

Question 13

Lower medial arm bone

Answer 13

Ulna

Question 14

Superior arm bone

Answer 14

Humerus

Question 15

Articulates ulna with the Trochlea of the humerus, open mouth, curve of crescent

Answer 15

Trochlear notch

Question 16

Beak-like projection at the base of the ulna’s trochlear notch, bottom lip of curve. Slips into coronoid fossa of humerus when flexing elbow

Answer 16

Coronoid process

Question 17

Smooth articular surface of the ulna for the radius. Lateral

Answer 17

Radial notch

Question 18

Distal, lateral round articulation point of ulna for distal radius

Answer 18

Radial articulation

Question 19

Sharp lateral end of ulnar shaft, supports the interosseous membrane which stretches between ulna and radius

Answer 19

Interosseous crest

Question 20

Sharp projection on medial, distal end of ulna. Sharp pointy part of bone

Answer 20

Styloid process

Question 21

Lateral lower arm bone

Answer 21

Radius

Question 22

Rounded proximal end of radius, articulates superiorly with capitulum and medially with radial notch

Answer 22

Radial head

Question 23

Slender area between radius’s head and radial tuberosity

Answer 23

Neck

Question 24

Blunt, rugged attachment on radius for biceps muscle. Located anteriorly and medially

Answer 24

Radial tuberosity

Question 25

Sharp, medial edge of radial shaft. Attachment point for the interosseous membrane, medial, extremely sharp

Answer 25

Interosseous crest

Question 26

Concave, articular surface on medial, distal end of radius. Articulates with the convex part of ulna

Answer 26

Ulnar notch

Question 27

Projection on posterior, distal surface of radius

Answer 27

Dorsal tubercle

Question 28

Distal, inferior point of articulation on radius for two bones of the wrist (scaphoid and lunate)

Answer 28

Distal radial articular surface

Question 29

Distal, lateral sharp projection of radius

Answer 29

Styloid process
