Pinna
The visible part of the ear that resides outside of the head.
Auditory Canal
A tube running from the outer ear to the middle ear.
Outer Ear
The outer ear consists of the pinna, and the ear canal.
Tympanic Membrane
Or “the eardrum” is a thin, cone-shaped membrane that separates the external ear from the middle ear.
The inner ear is composed of what?
The cochlea, auditory-vestibular nerve, and the oval window.
Cochlea
A snail-shell like structure divided into three fluid-filled parts.
Auditory-Vestibular Nerve
A sensory nerve that conducts two special senses: hearing (audition) and balance (vestibular).
Oval Window
Separates the air-filled middle ear from the fluid-filled inner ear.
The word “taste” may be better described as what?
“Flavor.”
Define “flavor.”
A combination of gustation, olfaction, somatosensation.
Prepyriform Cortex (Primary Olfactory Cortex)
The primary olfactory cortex is a portion of the cerebral cortex involved in olfaction.
