400
The external acoustic meatus of the external ear is lined with _____________ that produces ___________.
What is ceruminous glands; wax?
400
Describe how static equilibrium works.
What is the otoliths are pulled in a certain direction due to gravity, causing otolithic membrane to bend the hair tufts of the hair cells, sending stimulus to the vestibular nerve
400

500
The ear houses the two senses of ___________ and __________ and has ________________(type of receptors).
What is hearing; balance; mechanoreceptors?
500
Discuss dynamic equilibrium. Name the receptor organ, receptor cell, and how it works.
What is the semi circular canals, crista ampularis, and the endolymph is moved over the cupula, causing the hair cells to bend, sending a signal to the vestibular nerve
