humerus
bone extending from the shoulder to the elbow
capitulum
bump opposite the trochlea, rounded, lateral and distal (humerus)
coronoid fossa
anterior surface, distal end, indentation above trochlea (humerus)
greater tubercle
rough part of shaft on the lateral side, quarter of the way down the shaft (humerus)
head
the rounded ball shaped part of the humerus
lateral epicondyle
distal end of the humerus, smaller bump
lateral supracondylar crest
runs above lateral condyle on the humerus, ridge of bone
lesser tubercle
bump on the anterior surface of the head (humerus)
medial epicondyle
distal end of the humerus, larger bump, same side as ball of head
medial supracondylar crest
runs above medial condyle on the humerus, ridge of bone
nutrient foramen
small hole on the shaft of the long bones
olecranon fossa
distal end of the humerus, posterior side, large indentation
radial fossa
smaller / shallow dent above the capitulum of the humerus, distal end, anterior surface
spiral groove
twisty part of humerus shaft
shaft
main part of the long bones
trochlea
half of a spindle shape bump, medial / distal end of the humerus
radius
lateral lower arm bone, 'connects' to thumb
distal radial articular surface
suface of the radius that connects to the wrist
dorsal tubercle
large bump on the posterior surface of the distal end, radius
head
the rounded smaller portion of the radius that connects to the capitulum, shaped like a red blood cell
interosseous crest
sharp edge of the radius shaft, medial, faces the ulna
neck
pushed in portion just below the head of the radius
radial tuberosity / bicipital tuberosity
bumped out portion on the radius just below the neck/head, anteior and medial
styloid process
on the distal surface of the radius, most protruding part of the triangle
ulnar notch
medial side of the distal surface of the radius, indentation
ulna
medial lower arm bone
coronoid process
bottom part of the moon shap on the ulna
extensor carpi ulnaris groove
indentation next to the styloid process of the ulna, distal end
interosseous crest
sharp edge of the ulna shaft, lateral, faces the radius
olecranon process
upper part of the moon shape on the ulna
radial notch
groove near the the bottom of the moon shape, lateral articulation surface
styloid process
pointy bit on the distal end of the ulna, heel on boot
trochlear notch
half-moon indentation of the ulna
