Senses Exam

Front

What is the retina?

Back

The retina is a thin layer of tissue located at the back of the eye that contains light-sensitive cells (photoreceptors) which convert light into electrical signals sent to the brain.

Front

What is the choroid?

Back

The choroid is a layer of blood vessels and connective tissue between the retina and the sclera (the white part of the eye) that provides nourishment to the retina.

Front

What is the function of the olfactory bulb?

Back

The olfactory bulb is a structure in the brain that processes information about odors detected by the olfactory receptors in the nasal cavity.

Front

What is the role of the semicircular canals?

Back

The semicircular canals are part of the inner ear that help maintain balance by detecting rotational movements of the head.

Front

What is a blind spot in the eye?

Back

The blind spot is the area on the retina where there are no photoreceptors, resulting in a lack of vision in that specific area.

Front

What is the function of cilia in the nasal cavity?

Back

Cilia are tiny hair-like structures that help move mucus and trapped particles out of the nasal cavity, aiding in the sense of smell.

Front

What is the vestibule?

Back

The vestibule is a part of the inner ear that helps with balance and spatial orientation by detecting linear accelerations.

Front

What is the eardrum?

Back

The eardrum, or tympanic membrane, is a thin membrane that vibrates in response to sound waves, transmitting sound to the middle ear.

Front

What is the fovea?

Back

The fovea is a small pit in the retina that contains a high concentration of photoreceptors, providing the sharpest vision.

Front

What is the nasal cavity?

Back

The nasal cavity is the space behind the nose that filters, warms, and humidifies the air we breathe, and contains olfactory receptors for smell.
