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
