Function: the Skull model consists of 3 parts.Skull cap, facial skeleton base, and lower jaw bone are individual pieces included in this skull anatomy model; The fully removable mandible jaw and skull cap offer a deeper look into the skull bone model to review the endocranium cavity and sinus cavities.the brain model consists of 8 components: sagittal section of brain, cerebral hemisphere, cerebellum and brainstem. It also shows the cerebral hemisphere, diencephalon, cerebellum and brainstem midbrain, pons, medulla oblongata, and cerebral nerves.etc.Good learning resources.The brain model includes a labeled diagram for 32 numeric marker.You can clearly see all the main anatomical structures of the human skull,human brain and cervical vertebra.The accuracy of this anatomy model is the perfect study tool for anatomy students.Human skull and brain with cervical vertebra anatomy model on base for use in for patient education or anatomical study,it is a great teaching tool.Material:The model is made of PVC, which is corrosion resistant, lightweight, and has high strength.
