Shoulder Girdle and Upper Extremity (exam 1)

clavicle

collar bone

sternal end

round and think; attaches to clavicular notch of sternum

acromial end

flat, paddle shaped lateral end; it attaches to acromion process of the scapula

scapula

shoulder blade; articulates with the clavicle and humerus

acromion process

continuous with the scapular spine; extends laterally, posterior and superior to the glenoid cavity

coracoid process

projects anterior and superior to the glenoid cavity

glenoid fossa

site of articulation with humerus

infraspinous fossa

region inferior to the scapular spine on the posterior view

spine of the scapula

ridge that crosses the posterior surface of the body before ending at the medial border

subscapular fossa

depression in the anterior surface of scapula

supraspinous fossa

region superior to the scapular spine

inferior angle

bottom point of scapula

superior angle

uppermost aspect of scapula where medial border meets superior border

lateral border

medial border

infraglenoid tubercle

prominence inferior to the glenoid cavity

supraglenoid tubercle

superior border

humerus

extends from the scapula to the elbow

head

proximal end of the humerus and articulates with scapula at the glenoid cavity

anatomical neck

marks the extent of the joint capsule

surgical neck

inferior to the greater tubercle where the shaft starts to taper

greater tubercle

larger projection; anterior and lateral

lesser tubercle

smaller projection; anterior and medial

intertubercular groove

positioned between the greater and lesser tubercles; biceps tendon runs along groove

deltoid tuberosity

large, rough elevation on the lateral surface of the shaft, approximately halfway along its length.

radial groove

crosses inferior end of deltoid tuberosity; marks path of radial nerve

radial fossa

depression on the anterior, distal end of the humerus superior to the capitulum on lateral side

coronoid fossa

depression on the anterior surface of the humerus above the trochlea; this space receives the coronoid process of the ulna when the elbow is maximally flexed

olecranon fossa

posterior distal depression above the trochlea

lateral epicondyle

projection on the lateral condyle

medial epicondyle

projection on the medial condyle

capitulum

round lateral structure that articulates with the radius

trochlea

spool shaped medial portion of condyle; most distal portion of the humerus

ulna

medial bone of the forearm (pinky side)

radius

lateral bone of the forearm (thumb side)

olecranon process

superior end of the ulna

trochlear notch

articulates with the trochlea of the humerus to form elbow joint

coronoid process

forms the interior lip of the trochlear notch

radial notch

articulates with the head of the radius at the proximal radioulnar joint; always on the lateral side of ulna

styloid process

posterior; lateral surface of the ulnar head

styloid process

portion on the radius

ulnar head

distal bulge

radial head

articulates with the capitulum of the humerus

neck (radius)

extends from the radial head to the radial tuberosity

radial tuberosity

attachment site of the biceps brachii muscle

ulnar notch

depression on the anterior medial surface of the radius; articulates with the head of the ulna at the radio-ulnar joint

carpals

wrist; contains 8 small bones arranged in 2 rows

So Long To Pinky Here Comes The Thumb

what is the pneumonic device to remember the wrist bones (start on thumb side)

scaphoid

the proximal carpal bone on the lateral border of the wrist

lunate

Lies medial to the scaphoid and articulates with the radius

pisiform

sits anterior to the triquetrum

triquetrum

Small pyramid-shaped bone medial to the lunate; articulates with the articular disc that separates the ulnar head from the wrist.

trapezium

lateral bone of the distal row

trapezoid

medial to the trapezium

capitate

sits between the trapezoid and the hamate

hamate

the medial distal carpal bone

metacarpals

the five bones that form the palms of the hand

Proximal phalanges

middle phalanges

distal phalanges

pollex

First digit of the hand; another name for the thumb

sternum

breastbone

manubrium

jugular notch

clavicular notch

facet for the cartilage of rib 1

#6

body

sternal angle

facet for the cartilage of rib 2

#7

xiphoid process

Costoclavicular ligament impression

conoid tubercle

trapezoid line

facet for the clavicle

scapular notch

ulnar nerve sulcus

interosseous border

sharp medial edge on both the radius and the ulna

ulnar tuberosity

hook of hamate
