Unit 7 - Special Senses - Unit Summative

Front

What are chemoreceptors?

Back

Chemoreceptors are sensory receptors that respond to chemical stimuli in the environment, such as taste and smell.

Front

What is the focal point in relation to the eye?

Back

The focal point is the point where all horizontal light rays that enter the eye converge after passing through the lens.

Front

Describe the pathway of light through the eye.

Back

The pathway of light through the eye is: cornea, aqueous humor, through pupil, lens, vitreous humor, retina.

Front

What is the function of the olfactory bulb?

Back

The olfactory bulb processes information about odors detected by the olfactory neurons.

Front

What is the cribriform plate?

Back

The cribriform plate is a bony structure in the skull that allows olfactory nerves to pass from the nasal cavity to the olfactory bulb.

Front

What role do olfactory neurons play in the sense of smell?

Back

Olfactory neurons are responsible for detecting odor molecules and transmitting signals to the brain.

Front

What are olfactory hairs?

Back

Olfactory hairs are tiny hair-like structures on olfactory neurons that detect odor molecules.

Front

Explain the role of the lens in the eye.

Back

The lens focuses light onto the retina, allowing for clear vision.

Front

What is the vitreous humor?

Back

The vitreous humor is a gel-like substance that fills the space between the lens and the retina, helping to maintain the eye's shape.

Front

What is the aqueous humor?

Back

The aqueous humor is a clear fluid that fills the space between the cornea and the lens, providing nutrients and maintaining intraocular pressure.
