Measuring 70" tall, models are medical-grade, exact replicas of the skeleton of an adult male. Made of durable, unbreakable and washable plastic material with a three year guarantee. Arms and legs allow demonstration of natural movements and can be detached for closer study. All joints, including hands and feet, are properly articulated and securely wired. Detachable skull can be dissected into three parts: calvarium, base of skull and lower jar. Lower jaw is spring articulated to demonstrate movements. Choose skeletal models pelvic-mounted on a roller stand or skull mounted on 5-arm hanging roller stand. Both include dust cover.
