Flashcard 41: _____ is responsible for inducing phototransduction.

Answer: Metarhodopsin II (Compound)

Flashcard 42: _____ are more sensitive to light

Answer: Rods (Cones/Rods)

Flashcard 43: Doctrine of _____ states that when the nerve pathways from a particular sense organ are stimulated, the sensation evoked is that for which the receptor is specialized

Answer: specific nerve energies

Flashcard 44: Frequency-specific regions of the cochlea produce _____ which reflect the motility status of the cochlea's outer hair cells

Answer: otoacoustic emissions

Flashcard 45: _____ of sounds is a function of the middle ear

Answer: Amplification (Dimunition/amplification)

Flashcard 46: Total transformer ratio of the middle ear is _____

Answer: 22:1

Flashcard 47: Ratio of effective vibratory area of tympanic membrane to area of footplate of stapes (areal ratio) is _____.

Answer: 17:1 

Flashcard 48: b-wave on ERG originates from _____

Answer: Muller and bipolar cells

Flashcard 49: _____ theory assumes three sets of receptor systems, each of which functions as an antagonistic pair

Answer: Opponent process

Flashcard 50: What is the function of the crista ampullaris?

Answer: Detection of angular acceleration (rotation)

Extra: The crista ampullaris is the sensory organ located in the semicircular canals. It detects angular acceleration and deceleration (rotational movement). In contrast, the maculae (in the utricle and saccule) detect linear acceleration and gravity.
