What are rods and cones?

Back

Rods and cones are photoreceptor cells located in the retina of the eye. Rods are responsible for vision in low light conditions, while cones are responsible for color vision and function best in bright light.

Front

What is the function of the choroid?

Back

The choroid is a layer of blood vessels and connective tissue between the retina and the sclera that provides nutrients and oxygen to the outer layers of the retina. It does not produce tears.

Front

What is the role of the iris in the eye?

Back

The iris is the colored part of the eye that controls the size of the pupil, regulating the amount of light that enters the eye.

Front

What is the olfactory bulb?

Back

The olfactory bulb is a brain structure that receives neural input about odors detected by cells in the nasal cavity.

Front

What is static equilibrium?

Back

Static equilibrium refers to the sense of balance and orientation in space, primarily maintained by the movement of otoliths along hair cells in the inner ear.

What is the function of the tympanic membrane?

Back

The tympanic membrane, or eardrum, vibrates in response to sound waves, transmitting sound to the ossicles in the middle ear.

Front

What is the cochlea?

Back

The cochlea is a spiral-shaped organ in the inner ear that converts sound vibrations into neural signals for the brain to interpret.

Front

What are hair cells?

Back

Hair cells are sensory cells located in the inner ear that detect sound vibrations and contribute to the sense of hearing and balance.
