| Question | Answer |
|---|---|
| External Ear | Pinna, External Auditory Canal, Tympanic Membrane, |
| External ear can change in | Pressure and is filled with air |
| External also called... | Pinna |
| Pinna | Cartilage of ear, Also called Auricle |
| Tympanic membrane (ear drum) | Is where sound waves hit, Separates the external auditory canal from the middle ear |
| Middle Ear | Eustachian tube, Auditory Ossicles (3) |
| Middle ear can change in | Pressure and is filled with air |
| Eustachion Tube (Auditory Tube) | Leads to throat, equalization of pressure |
| Auditory Ossicles | Malleus, Incus, Stapes |
| Malleus (Hammer) | Connected to tympanic membrane |
| Incus (Anvil) | Amplifies movement of the Malleus |
| Stapes (Stirrup) | Connected to oval window |
| Stapedius is the | Smallest muscle in the body |
| Inner Ear | Fluid filled and solid |
| Inner consists of.... | Cochlea, Vestibule, Bony Labyrinth |
| Cochlea | Hearing |
| Cochlea consists of... | Oval window and Round window |
| Oval window | Membrane that connects to auditory ossicles, connects with the Stapes |
| Round Window | Membrane that permits pressure changes, place where perilymph expands to. |
| Vestibule | For equilibrium, connects the cochlea to the semicircular canals. |
| Semicirular Canals | Balance |
| Anterior Semicircular Canals | Respond to nodding of head |
| Posterior Semicircular Canals | Respond to sideways tilting of head |
| Lateral Semicircular Canals | Respond to horizontal rotation of head |
| Ampulla | Contains sensory receptors |
| Bony Labyrinth | Bone surrounding Cochlea and Vesibule |
| External Auditory Canal | Sound waves travel through it |
| Saccule & Utricle are involved with | Foward and backward movement |
| Organ of Corti | Contains fluid; endolymph |
| Stereocilia | Branch to form cochlear nerve, hair cells in endolymph |
