Bones

lesser tuberosity, greater tuberosity, intertubercular groove

lateral to the head of the humerus are two bony swellings called _______________, ________________. These are sites of muscle attachment- the space between them is called the _______________ _________.

carpal articular surface, styloid process of the radius

located at the distal end of the radius is the flattened ______________________ and the lateral, pointed bony extension known as the _____________________________.

head of the ulna

flattened, distal articular surface of the ulna

proximal, middle, distal

Each individual phalanx is identified (relative to the metacarpals) as ___________, _________, __________.

subscapular fossa

anterior surface of the scapula

radial notch

a crescent moon-shaped indentation on the part of the trochlear notch not on the olecranon. it is the ulna's proximal articular surface for the radius.

olecranon fossa

a second articular surface for the ulna located on the posterior surface of the distal humerus- articulates with the olecranon of the ulna

head of the radius

at the proximal end of the radius is the rounded _________________, which is the articular surface of the radius at the capittelum of the humerus

scapular spine

attaches the acromion to the body of the scapula

ulnar tuberosity

bony swelling on the anterior surface of the ulna near the proximal end, site of muscle attachment

glenoid cavity

feature of the scapula. a flat and round cavity that serves as the articular surface for the humerus.

coracoid process

feature of the scapula. anterior to the glenoid cavity- long, cylindrical bony extension. serves with the acromion as sites of muscle attachment and sites of attachment for ligaments that hold the shoulder together.

acromion

feature of the scapula. posterior to the glenoid cavity- large, flattened bony extension. serves with the coracoid process as sites of muscle attachment and sites of attachment for ligaments that hold the shoulder together.

trochlear

on the anterior surface of the olecranon is a smooth articular surface called the ____________________. This extends to the flattened, top part of the ulna.

lateral epicondyle

opposite the medial epicondyle. origin for the muscles that extend the wrist and hand.

infraspinous fossa

posterior surface of the scapula

medial epicondyle

rounded extension from the medial aspect of the distal humerus- serves as the origin for the flexor muscles of the wrist and hand. (on the same side as the head of the humerus)

clavicle

s-shaped bone which runs horizontally between the top of the sternum (breastbone) and (scapula) shoulder blade. helps connect the arm to the body.

scapula

shoulder blade. connects the humerus (upper arm bone) with the clavicle (collar bone).

thumb side

the 5 metacapral bones and the phalanges are named 1st through 5th beginning on the ________ _______.

capitellum

the articular surface for the radius- next to the lateral epicondyle of the humerus

trochlea

the articular surface for the ulna- between the medial epicondyle and the capitellum

supraspinous fossa

the depression on the superior aspect of the scapula

lateral border

the edge of the scapula bone below the glenoid cavity that extends down to the bottom of the bone

lunate, scaphoid, trapezium, trapezoid, capitate, hamate, triquetrum, pisiform

the eight carpal bones- beginning just distal to the head of the ulna and and proceeding in an arc, first toward the thumb and then around toward the little finger. (if you can only count seven carpels you know you are looking at a dorsal view)

olecranon

the large, bony extension at the top of the ulna. fits into the olecranon fossa of the humerus.

radius

the lateral (thumb side) of the two antebrachial (forearm) bones. smaller at proximal end and bigger at distal end.

ulna

the medial (pinky side) of the two antebrachial (forearm) bones. Larger at the proximal end and smaller at the distal end.

acromial, sternal

the short end (_________ end) of the clavicle articulates with the scapula, whereas the long end (_________ end) articulates with the sternum.

medial border

the superior to inferior edge of the scapula bone opposite the lateral border

radial tuberosity

the swelling a short ways distal to the head of the radius- site of muscle attachment.

supraspinatus muscle, subscapularis muscle, infraspinatus muscle

the three muscles housed within the scapula

styloid process of the ulna

thin bony extension of the ulna
