Anatomically, the model shows the different muscle groups of the upper limb, including the muscle groups of the shoulder, upper arm, forearm and hand.
In addition, the model shows the largest arteries and nerves, as well as their relationship to the various muscles. Since the focus of the model is precisely the relationships of the muscles, the model's various joints are shown in a very light degree of detail, and these are also not movable.
As mentioned, the muscles in 5 of the superficial muscle groups are removable so that the deeper structures become visible. The muscles in question are listed below, it is stated in parentheses which muscle group they belong to).
M. brachialis, M. extensor carpi radialis longus and brevis (all part of the radial extensor log).
M. pronator teres, M. flexor carpi radialis, M. palmaris longus, M. flexor carpi ulnaris and M. flexor digitorum superficialis (the superficial muscles of the flexor joint of the forearm).
M. extensor digitorum manus, M. extensor digiti minimi, M. extensor carpi ulnaris and M. anconeus (the superficial muscles of the extensor log of the forearm)
M. biceps brachii (caput longum and caput breve) (part of the flexor tendon of the upper arm)
M. deltoideus (part of the shoulder musculature)
