Ulna (proximal)

Radial Notch

receives the radius

Trochlear Notch

ulna articulates with the trochlea of the humerus

Coronoid Process

Forms part of the articulation of the elbow

Olecranon Process

Humerus- distal

Lateral & Medial Epicondyle

Capitulum

Radius

Trochlea

Ulna

Ulna (distal)

Radius

Radial Tuberosity

below the head is the radial tuberosity, a point of muscle attachment

Styloid Process

a projection of bone on the lateral surface of the distal radius bone

Neck

distal to the head and proximal to the tuberosity

articulates with the capitulum of the humerus.

Humerus- proximal

Head

Glenoid fossa of scapula

Greater and lesser tubercle

Deltoid Tuberosity

Humerus- landmarks of articulation

Olecranon fossa

olecranon process of the ulna fits here during extension.

radial fossa

articulates with head of radius

Coronoid fossa

fits into the cornoid process during flexion
