General Senses
These senses include touch, pressure, pain, and temperature.
What are the general senses?
The colored part of the eye that controls pupil size.
What is the iris?
The three small bones of the middle ear.
What are the ossicles?
These senses include smell, taste, sight, hearing, and balance.
What are the special senses?
Sensory receptors convert stimuli into these.
What are nerve impulses?
Receptors that respond to tissue damage are called these.
What are nociceptors?
The light-sensitive layer of the eye.
What is the retina?
The snail-shaped structure responsible for hearing.
What is the cochlea?
The sense of smell is also called this.
What is olfaction?
Receptors that respond to light energy.
What are photoreceptors?
These receptors respond to changes in temperature.
What are thermoreceptors?
These photoreceptors are responsible for color vision.
What are cones?
This structure separates the outer ear from the middle ear.
What is the tympanic membrane (eardrum)?
Taste receptors are located in these structures on the tongue.
What are taste buds?
This division of the nervous system carries sensory input to the CNS.
What is the sensory (afferent) division?
The sense that allows you to know body position without looking.
What is proprioception?
The area of sharpest vision on the retina.
What is the fovea centralis?
The part of the ear responsible for balance.
What is the vestibular apparatus?
The sense that often works closely with taste to identify food.
What is smell?
The minimum strength of a stimulus needed to activate a receptor.
What is threshold?
Receptors that detect changes in pressure and touch are called these.
What are mechanoreceptors?
This condition results from the lens losing elasticity with age.
What is presbyopia?
The fluid-filled canals that detect rotational movement.
What are the semicircular canals?
These receptors respond to chemical stimuli.
What are chemoreceptors?
The ability of receptors to become less sensitive to constant stimuli.
What is sensory adaptation?
