High magnification shows in detail the detailed structure of the ear, the organ of hearing and sense of place. The ear consists of three parts: the outer ear, the middle ear and the inner ear. Auditory receptors and baroreceptors are located in the inner ear, which is why the ear is also called the baroreceptor. Some people also list the outer and middle ear as appendages of the potential hearing apparatus. The outer ear consists of the auricle and the external auditory canal. The model has a movable portion of the external auditory canal in the rocky part of the temporal bone, a labyrinth that can be picked up and opened, and a separable tympanic membrane, hammer bone, and anvil bone. It consists of 5 parts: outer ear, middle ear, temporal bone rock part and inner ear labyrinth, and displays the structures of auricle, outer ear canal, middle ear drum chamber, eardrum and auditory ossicles, eustachian tube, as well as temporal bone rock part and inner ear labyrinth, etc. It shows in detail the anatomical structures of the human outer, middle and inner ear. There are dozens of parts to be indicated by the labeling. Size: 4 times enlarged, 21cm high, 33cm wide, 23cm thick. Material: environmentally friendly PVC material, environmentally friendly paint, computer color matching, advanced hand-painted.Size: Enlarged 4 times, 21cm high, 33cm wide, 23cm thick.
