This 7-part life-size model demonstrates the anatomical structure of the human arm in detail, including both superficial and deep muscle layers along with associated vascular structures, nerves, and ligaments. The shoulder region and hand are also accurately represented to provide a complete understanding of upper limb anatomy. The model includes removable parts such as the deltoid muscle, biceps muscle, triceps muscle, long palmar muscle with radial structures, flexor muscles of the wrist, brachioradialis muscle, radial extensor muscles of the wrist, and the palmar aponeurosis, allowing for detailed study of individual components.
