Introducing the Classic Human Skeleton from Axis Scientific. Standing 5 feet 6 inches tall, this skeleton towers over the competition. His skull is easily detachable from the body of the skeleton. The skull features a removable calvarium, or skull cap, secured with pegs as well as magnets for added stability. Inside the skull, every suture, foramen, and groove is visible, allowing for a full study of the internal and external structures alike. It also features the spinal nerves. The hyoid bone is present, and is easy to study with or without the skull in place. The skeleton is fully articulated, and can replicate all natural movements at the joints. The arms can clearly display flexion, extension, abduction and adduction, circumduction of the shoulder, and even pronation and supination of the radial-ulnar joint. Similarly, the legs can perform all of the movements of the acetebulofemoral joint and knee. Included with the Axis Scientific Classic Human Skeleton is an incredibly comprehensive full color product manual featuring 172 listed landmarks developed by leading medical professionals.. Also included with the Classic Human Skeleton is our brand new Study and Numbering bundle.
