2. Sound waves hitting the eardrum set it into vibration. Trace the pathway through which vibrations and fluid currents travel to finally stimulate the hair cells in the spiral organ of Corti. Name the appropriate ear structures in their correct sequence. eardrum R ____ R R R oval window R R R R hair cells 3. Complete the following description of the static and dynamic equilibrium receptors by writing the key choices in the answer blanks. KEY CHOICES: angular gravity semicircular canals cupula perilymph static dynamic proprioception utricle endolymph saccule vision The receptors for (1)_ equilibrium are found in the crista ampullaris of the (2)_. These receptors respond to changes in (3)_ motion. When motion begins, the (4)_ fluid lags behind and the (5)_ is bent, which excites the hair cells. When the motion stops suddenly, the fluid flows in the opposite direction and again stimulates the hair cells. The receptors for (6)_ equilibrium are found in the maculae of the (7)_ and (8)_. These receptors report on the position of the head in space. Tiny stones found in a gel overlying the hair cells roll in response to the pull of (9)_. As they roll, the gel moves and tugs on the hair cells, exciting them. Besides the equilibrium receptors of the inner ear, the senses of (10)_ and (11)_______ are also important in helping maintain equilibrium.

3. Complete the following description of the static and dynamic equilibrium receptors by writing the key choices in the answer blanks.

KEY CHOICES:
angular gravity semicircular canals
cupula perilymph static

endolymph saccule vision

The receptors for (1)_______________ equilibrium are found in the crista ampullaris of the (2)_______________. These receptors respond to changes in (3)_______________
motion. When motion begins, the (4)_______________ fluid lags behind and the (5)_______________ is bent, which excites the hair cells. When the motion stops suddenly, the fluid flows in the opposite direction and again stimulates the hair cells. The receptors for (6)_______________ equilibrium are found in the maculae of the (7)_______________ and (8)_______________. These receptors report on the position of the head in space. Tiny stones found in a gel overlying the hair cells roll in response to the pull of (9)_______________. As they roll, the gel moves and tugs on the hair cells, exciting them. Besides the equilibrium receptors of the inner ear, the senses of (10)_______________ and (11)_______________ are also important in helping maintain equilibrium.
