Term
fovea articularis
Definition
AKA articular facet

concavity on the proximal end of the radius that receives the capitellum of the humerus
Term
circumferentia articularis
Definition
rimlike surface around the head of the radius for articulation with the radial notch of the ulna
Term
radial tuberosity
Definition
on medial aspect of radius about 2 cm distal to its proximal end for attachment of the biceps brachii muscle.
Term
Lister's tubercle
Definition
AKA dorsal radial tubercle

bony ridge that is often palpable through the skin between the grooves for the externsor pollicis longus and the extensor carpi radialis brevis muscles.
Term
syloid process

roughened area distal to the coronoid process for attachment of the brachialis muscle
Term
radial notch
Definition
superolateral surface for articulation with the articular circumference of the radius.
Term
supinator crest
Definition
bony ridge extending distalward from the radial notch on the posterior surface of the shaft that gives origin to the supinator.
