Joint Project

The discussion encompasses the anatomical structures and landmarks relevant to the bones of the upper extremity, specifically focusing on the humerus, ulna, and radius. Key features include the greater and lesser tubercles of the humerus, the head which interacts with the glenoid fossa of the scapula, and the deltoid tuberosity.

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
