Anatomical models of the arm or upper extremity – for teaching, training, demonstration and understanding of the arm and shoulder girdle for use in medical, healthcare, and educational settings
The human arm or upper extremity is a highly functional component of the human body. Comprising the scapulothoracic articulation, shoulder joint, elbow joint, wrist joint, and hand, the human arm is capable of large and multi-joint movements such as throwing an object to small and fine motor skill movements.
The shoulder girdle (scapula and clavicle) is capable of moving across the thoracic rib cage with articulations at the sternoclavicular joint and acromioclavicular joint, producing greater range of motion possibilities. The shoulder joint is an enarthrodial joint and capable of movement in 3 planes of motion for greater mobility. The elbow joint is a ginglymus joint, capable of movement in only one plane of motion, but provides more stability to the arm. The radioulnar joint provides for rotational movements (supination and pronation) so the forearm and hand can be turned downward or upward. The wrist joint is a condyloidal joint allowing movement in two planes of motion. At the end of the arm, and included as a component of the arm, is the hand with all its intricate and multi-functional capabilities. The bottom line with all these joints and levers and the muscles acting on them is that the human being is capable of placing his/her arm in a vast array of positions to perform a wide-variety of movements and functions.
Our 3D Scientific arm models with 3D Smart Anatomy and removable muscles, allows students to dive into learning the orientation and structure of the arm for a greater understanding of the workings of the upper extremity.
