Temporal bone & internal ear
Product code: HB70303

Single Side Left or right side of a region / system / organ.
The morphology of the temporal bone is complex due to its varied roles. It contributes to the structure of the cranium, articulates with the mandible, conveys various cranial nerves, provides attachment for muscles and ligaments, and houses the ear and vestibular system. This Bones specimen provides uninterrupted views of the morphology, features, landmarks, and joint surfaces of temporal bone. The intraosseous location of the cochlea, vestibular system and middle ear are also revealed alongside the course of the facial (CN VII) and vestibulocochlear (CN VIII) nerves, and the auditory ossicles.
