The temporal bone
modelled in plaster, 1:10 scale.
1. The eardrum. 2. The malleus; the handle of the malleus is attached to the eardrum. 3. The incus; its short process projects backward and is connected to the stapes (4). Sound is transmitted through tremors of the eardrum via these movable ossicles to the soft parts of the vestibule. At the same time, sound also enters the cochlea (6) through a round orifice and is transmitted to the brain via the auditory nerve (7) in the vestibule and in the cochlea (for the interior of the cochlea, see No. 60, Fig. 5). 8. The tensor timpani muscle, which tightens the eardrum. 9. Eustachian tube, connected to the nose. 10. Carotid artery. 11. A part of the temporal bone, which is attached to the labyrinth.
