The transmission pathway for olfactory sensations is olfactory cilia, olfactory bulb, olfactory tract, and cerebral cortex.

The number of pure, or "primary," olfactory scents is about 15.

Explain why the smell of a hospital or dentist's office can bring about negative emotions and why the smell of baking cookies or a baking turkey around Thanksgiving time can bring about positive emotions.

The number of sound waves that occur during a specific timeframe is called its frequency.

The hearing sense organ is the organ of Corti.

Match each outer ear term with its corresponding description. -Earwax

Because rhodopsin is less sensitive to light than the cone photopigments, brighter light is necessary for its breakdown.

The auditory ossicles include the malleus, incus, and stapes.

Of all the papillae on the tongue, which one contains the most taste buds?

Which of the following structures is not a component of the external ear?

Match each structure of the eye with its corresponding description. -Humor found in the posterior chamber

What is the difference between static and dynamic equilibrium? Where are the sense organs for each located?

The tip of the tongue reacts best to sweet taste.

Palpebrae is the scientific name for the eyelashes.

Explain the olfactory pathway. Why is it possible to link odors so powerfully to memory?

The correct order of the auditory ossicles deep to the tympanic membrane is malleus, incus, and stapes.

Unlike other neurons, olfactory receptors are replaced on a regular basis.

The stapes rests on the inner surface of the tympanic membrane, or eardrum.
