AP Psych Unit 1 Part 3

Front

What is the cochlea?

Back

The cochlea is a coiled, fluid-filled tube in the inner ear that transforms sound waves into nerve impulses.

Front

What is the correct sequence of structures that sound waves pass through to reach the auditory nerve?

Back

Eardrum → Ossicles → Cochlea → Hair cells → Auditory nerve.

Front

What does sensory interaction refer to?

Back

Sensory interaction is the principle that one sense may influence another, such as how smell can affect taste.

Front

Why is a time lag between left and right auditory stimulation important?

Back

It is important for accurately locating sounds.

Front

What is the vestibular sense?

Back

The vestibular sense is the ability to detect the position and movement of the body, particularly in relation to gravity.

Front

What role do hair cells play in hearing?

Back

Hair cells are sensory receptors located in the cochlea that convert sound vibrations into electrical signals for the auditory nerve.

Front

What is the function of the eardrum?

Back

The eardrum vibrates in response to sound waves, transmitting these vibrations to the ossicles.

Front

What are ossicles?

Back

Ossicles are three tiny bones in the middle ear (malleus, incus, stapes) that amplify sound vibrations from the eardrum to the cochlea.

Front

What is sensory adaptation?

Back

Sensory adaptation is the process by which our sensitivity to unchanging stimuli decreases over time.

Front

What is sensory deprivation?

Back

Sensory deprivation occurs when one or more of the senses are deprived of normal levels of stimulation.
