The Anatomy Lab micro desktop skeleton model is our smallest and most basic, entry-level skeleton offering. The model has easily removable and movable arms and legs, and a skull cap that removes from the model. The skull's jaw offers movement but does not remove from the model. The skeleton shows just the very basic anatomical detail of the spine, the ribs, and the skull. The model offers no flexibility in the spine or the neck. The micro skeleton is pelvically mounted to stand upright, and it's a perfect model for small areas. This is a simple and no-frills skeleton and it's a great choice for an entry level model that identifies the very basic anatomical landmarks of the human skeleton. This model is 19" tall and has a base that is 4.75" by 4.75".
