Eye & Ear

Front

What are chemoreceptors?

Back

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

Front

What is the function of the tympanic membrane?

Back

The tympanic membrane, or eardrum, is the first structure to transmit sound waves into the middle ear.

Front

Where are olfactory receptors located?

Back

Olfactory receptors are located in the nasal cavity, specifically in the olfactory epithelium.

Front

What is the cornea's role in vision?

Back

The cornea is the first part of the eye that light hits, helping to focus light onto the retina.

Front

What fluid is released when crying?

Back

Tears are the fluid released when crying, which can also drain into the nasal cavity.

Front

What is the function of the organ of Corti?

Back

The organ of Corti is responsible for converting sound vibrations into neural signals in the cochlea.

Front

What are the main types of sensory receptors in the body?

Back

The main types of sensory receptors include chemoreceptors, mechanoreceptors, thermoreceptors, and photoreceptors.

Front

How do sound waves travel through the ear?

Back

Sound waves travel through the ear by vibrating the tympanic membrane, which then moves the ossicles (stapes, incus, malleus) and ultimately stimulates the cochlea.

Front

What is the role of the lens in the eye?

Back

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

Front

What is the function of the cochlea?

Back

The cochlea converts sound vibrations into electrical signals that are sent to the brain.
