The long head runs along the inner side of the upper arm and travels from the scapula to the elbow. The lateral head is on the outer side of the upper arm and travels from the humerus to the elbow.
The triceps brachii has a potential to entrap the radial nerve in the triangular interval secondary to hypertrophy. The presence of a fibrous arch in the long head and lateral head further complicates the situation. Repeated forceful extension seen in weight training and sport involving punching may be a precedent to this scenario.
While executing a rope push-down, the palms face in and the arms internally rotate while pushing down. This variation works all three parts of the triceps, but especially the lateral head (coloured yellow Figure 2). [1] Figure 2: The triceps muscle, showing the lateral head (yellow), the long head (red) and the medial head (green).
It is one of the most stimulating exercises to the entire triceps muscle group in the upper arm, [citation needed] and works the triceps from the elbow all the way to the latissimus dorsi. Due to its full use of the triceps muscle group, the lying triceps extensions are used by many as part of their training regimen.

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 deltoid muscle, gives attachment to the triceps brachii behind, and to the brachialis, brachioradialis, and extensor carpi radialis longus muscles in front.
The triceps, or triceps brachii (Latin for "three-headed muscle of the arm"), is a large muscle on the back of the upper limb of many vertebrates. It consists of three parts: the medial, lateral, and long head. [1] It is the muscle principally responsible for extension of the elbow joint (straightening of the arm).
