Chapter 10, Problem 7aCP
Summary Introduction
 To review:
The structure of the utricle and saccule along with the stimulation of hair cells within these organs due to linear acceleration.
 Introduction:
The vestibular apparatus of the ear is very important for maintaining equilibrium with the surroundings, especially regarding horizontal, vertical, and spinning movements. The vestibular apparatus consists of two parts, namely the otolith organs and the semicircular canals. The utricle and saccule are structures found in the ear and are called otolith organs.

Students have asked these similar questions
for the rotational movement, do you mean that when I tilt my head to the right, the hair cells in my right cupula will be depolarized, and the hair cells on my left cupula will be hyperpolarized? I understand the concept that when stereocilia beats toward the kinocilia, the tiplings will open and cause K and Ca to enter the cell. But I'm so confused on how to know what movements exactly make the stereocilia beat toward the kinocilia and not against it?
Linear acceleration, such as the forward movement of being in a car, will result in
Depolarization or hyperpolarization of hair cells within the utricle and saccule.
Tonic release of neurotransmitters in the cochlea.
Depolarization of hair cells within the semicircular canals.
two of the above are correct
Explain briefly the signal transduction for the following senses:
i. Hearing.
ii. Vision.
