Ear

Auricle, external acoustic meatus, and tympanic membrane

What is found in the external ear?

Auricle

Cartilage covered by skin that funnels sounds waves into external acoustic meatus

External acoustic meatus

Conducts sound to tympanic membrane

Tympanic membrane

Separation between the external and middle ear and vibrates from sound waves

Ossicles, oval window, pharyngotympanic tube, tensor tympani muscle, and stapedius muscle

What is found in the middle ear?

Malleus, incus, and stapes

What are the ear ossicles (in order)?

Oval window

What is the stapes attached to/rocks in?

Pharyngotympanic tube

Tube that connects middle ear to nasopharynx

Vestibule composed of cochlea, semicircular canals, utricle, saccule, and internal acoustic meatus

What are found in the inner ear?
