scapula

(no other connection with any other bone besides the clavicle)

posterior scapula

(look for spine)

superior border of the scapula

medial border of the scapula

lateral border of scapula

superior angle of scapula

inferior angle of scapula

subscapular fossa

sits against rib cage

glenoid cavity

where the humerus articulates with the scapula

what synovial joint is the glenoid cavity? (glenohumeral joint)

ball and socket

coracoid process

acromion process

where the clavicle articulates

spine of scapula

supraspinous fossa

"above" the spine

infraspinous fossa

"below" the spine

head of humerus

medial (head articulates with body)

surgical neck

where you can commonly break the humerus

intertubercular sulcus

deltoid tuberosity

radial groove

runs down the posterior side of the shaft

coronoid fossa (anterior side)

radial fossa (anterior side)

olecranon fossa (posterior side)

glenohumeral joint

The synovial ball-and-socket joint of the shoulder

medial epicondyle

lateral epicondyle

the 2 parts of the condyle on the humerus

-capitulum (cap that sits on radius)

-trochlea (where the ulna interacts)

what is the only visible condyle on the posterior side?

trochlea (unla wraps all the way around)

anatomical neck of humerus

greater tubercle of the humerus

points out laterally

lesser tubercle of the humerus

points out medially

clavicle

collar bone

acromial end

what does the acromial end articulate with?

scapula

what 2 bones make up the forearm?

radius and ulna

which bone is on the medial side of the forearm?

ulna

which bone is on the lateral side of the forearm?

radius ("rad" thumbs up)

olecranon process of ulna

fits into the olecranon fossa of the humerus when forearm extends

trochlear notch of the ulna

"U" like structure (fits onto "bow-tie" like structure of the humerus"

coronoid process of ulna

coronoid fossa

when the forearm is flexed, the coronoid process fits here

head of ulna

styloid process of ulna

head of radius (cap)

articulates with capitulum of humerus (also fits into radial fossa)

neck of radius

radial tuberosity

styloid process of radius

pronation

turning the palm downward (dribble a ball)

supination

movement that turns the palm up (bowl of soup)
