Axis Scientific Human Ear Model, 5 Times Enlarged 4-Dimensional Ear Anatomical Model with 3 Parts Showing Major Regions of The Ear – Includes Base, Detailed Product Manual

5x Enlarged Ear Anatomy Model The Axis Scientific 3-Part Human Ear Model is an enlarged 4D model of the human ear. The ear’s two main functions of balance and hearing are aided by sensory organs and nerves found inside the ear. Common disorders and conditions of the ear include ear infections, tinnitus, and hearing problems. Vertigo is a balance disorder in the internal ear and is a symptom of a more serious condition. This human ear model is enlarged and 4-dimensional, creating a great visualization of the normal anatomy of the ear to aid in diagnostics and treatment of the conditions mentioned. External Ear The external or outer ear is represented on the model to help visualize the travel of sound from the external environment to the hearing nerves in the internal ear. Aside from sound, the external ear also provides protection through wax secretion. The enlarged ear model features three parts of the external ear: auricle, external acoustic meatus, and tympanic membrane. Middle Ear This enlarged ear model features removable auditory ossicles for a detailed study of their anatomy. The model provides a great visualization of how the ossicles fit against the tympanic membrane (eardrum) and the internal ear. This visualization can aid in understanding the physiology and function of the ossicles: transfer vibrations from the eardrum to the internal ear.
