Encyclopedia
The lower part of the lateral border of the body of the humerus
forms a prominent, rough margin, a little curved from behind forward, the lateral supracondylar ridge (or line), which presents an anterior lip for the origin of the Brachioradialis
above, and Extensor carpi radialis longus below, a posterior lip for the Triceps brachii, and an intermediate ridge for the attachment of the lateral intermuscular septum

Lateral intermuscular septum
The lateral intermuscular septum extends from the lower part of the crest of the greater tubercle of the humerus, along the lateral supracondylar ridge, to the lateral epicondyle; it is blended with the tendon of the Deltoideus, gives attachment to the Triceps brachii behind, to the Brachialis,...
