Your triceps actually comprise three heads : the long, the medial and the lateral. The largest of those is the lateral head. The lateral head is the one that’s furthest out to your side when standing naturally, which makes sense as the lateral plane is the one that goes directly out to your side.
Where is the lateral head located?
The lateral head arises from the dorsal surface of the humerus, lateral and proximal to the groove of the radial nerve, from the greater tubercle down to the region of the lateral intermuscular septum.
What separates the lateral and medial heads of the triceps?
There are two structures that separate the lateral and medial heads of the triceps brachii muscle. They are the radial nerve and the profunda brachii…

The triceps brachii is the muscle that runs down the back of the humerus, which is the long bone of the upper arm, and ends at the top of the ulna, which is the long bone of the forearm. The triceps brachii gets its name because it contains three muscle ‘heads’ or points of origin.
Do dips hit all three tricep heads?
As Coach Mike Robertson notes, “A basic rule of thumb should be this: If it uses more weight, it’s probably a more effective exercise. For the triceps, that means dips and close-grip bench presses.” Unlike some triceps movements, dips hit every head of the triceps: the long, medial, and lateral.
