Question

Quizplus · Accepted Answer

The cochlea contains the organ of Corti, which is responsible for transmitting auditory signals to the brain.

Answer: D
 The elastic membrane within the cochlea creates pressure waves in cochlear fluid, which helps to stimulate the hair cells of the organ of Corti.

Answer: F
 The cochlea is not a bone, but a spiral-shaped structure located within the inner ear. The bone in the middle ear is the stapes.

Answer: H
 The vestibular system, which includes the semicircular canals and otolith organs, helps to maintain balance and position and detects acceleration.

Answer: I
 Pitch is determined by the number of wave cycles per second, which is measured in units called Hertz (Hz).

Answer: J
 A pheromone is a chemical substance that elicits a response in members of the same species, often related to mating or other social behaviors.

Answer: K
 The iris controls the size of the pupil and the amount of incoming light, allowing for optimal visual perception in varying lighting conditions.
