DEFINITION 3

prominence on superior posterior portion of humerus;

insertion site for supraspinatus, infraspinatus, and teres

minor

TERM 4

humerus: intertubercular (bicipital) groove

DEFINITION 4

between greater & lesser tubercles; long head of biceps

brachii runs through groove

TERM 5

humerus: anatomical neck

DEFINITION 5

separates head from tubercles

humerus: surgical neck

narrow part distal to head & tubercles; common fracture site

TERM 7

humerus: deltoid tuberosity

DEFINITION 7

lateral protuberance on shaft; insertion site for deltoid

TERM 8

humerus: radial groove

DEFINITION 8

located on posterior shaft of humerus; radial nerve & deep

brachialartery run along this groove

TERM 9

humerus: medial supraepicondylar ridge

DEFINITION 9

ridge just superior to medial epicondyle

TERM 10

humerus: lateral supraepicondylar ridge

DEFINITION 10

ridge just superior to the lateral epicondyle; origin of

extensor carpi radialis longus m.

radius: head

proximal portion that articulates with capitulum of humerus

& radial notch of ulna; pivots within anular ligament

permitting pronation & supination

TERM 17

radius: neck

DEFINITION 17

narrow portion between the head and radial tuberosity.

TERM 18

radius: radial tuberosity

DEFINITION 18

projection from medial surface just distal to neck; insertion

sitefor biceps brachii

TERM 19

radius: ulnar notch

DEFINITION 19

indention at medial aspect of distal end; articulates with head

of ulna

TERM 20

radius: shaft

DEFINITION 20

enlarges towards wrist

radius: styloid process

small extension of bones lateral distal end (larger & extends

fartherdistally than ulnar styloid process); insertion site for

brachioradialis

TERM 22

humerus: lateral epicondyle

DEFINITION 22

lateral protuberance at distal end of humerus; origin of

commonextensor tendon for extensor muscles of posterior

forearm

TERM 23

ulna

DEFINITION 23

-Stabilizing bone of forearm; medial & longer of 2 forearm

bones-Does not reach the wrist, so not involved in wrist joint.

TERM 24

ulna: olecranon

DEFINITION 24

thick curved bony eminence at posterior aspect of proximal

ulna;insertion site for triceps brachii

TERM 25

ulna: coronoid

process

DEFINITION 25

triangular eminence projecting from anterior proximal

portion ofulna; insertion site for brachialis

ulna: styloid process

distal medial projection of ulna

TERM 32

carpal bones

DEFINITION 32

8 small bones located in the wrist

TERM 33

metacarpals

DEFINITION 33

5 bones that articulate with the carpal bones

(carpometacarpal joint) andproximal phalanges

(metacarpophalangeal joint)

TERM 34

phalanges

DEFINITION 34

small bones (proximal, middle, and distal phalanges) located

within the digits(thumb 2; other digits 3); create proximal

interphalangeal (PIP) and distal interphalangeal (DIP) joints
