Sight
This colored part of the eye controls the diameter of the pupil.
What is the iris?
These three bones in the middle ear amplify sound vibrations.
What are the ossicles (malleus, incus, stapes)?
True or False: All smells must pass through the thalamus to be processed by the brain.
What is False?
True or False: Taste buds for each sensation differ structurally.
What is False?
These receptors detect pressure, sound, touch, and vibration.
What are mechanoreceptors?
The electrical impulses from rods and cones travel to the brain via this nerve.
What is the optic nerve?
This structure vibrates in response to sound waves and is also called the eardrum.
What is the tympanic membrane?
Smells can evoke emotional memories due to direct connections with this part of the brain.
What is the cerebral cortex?
The five basic taste sensations include sweet, salty, sour, bitter, and this savory flavor.
What is umami?
These receptors respond to changes in chemical concentration, such as taste or smell.
What are chemoreceptors?
Photoreceptors that provide clear central vision and detect color and fine details in bright light.
What are cones?
This coiled, snail-like structure in the inner ear houses hair cells.
What is the cochlea?
This type of receptor is used in the detection of odors in the nasal passage.
What is a chemoreceptor?
These two tastes are most sensitive due to their connection with acids and toxins.
What are sour and bitter?
These receptors detect light and enable vision.
What are photoreceptors?
Photoreceptors that allow us to detect motion and help us see in dim light. Also provide peripheral vision.
What are rods?
These inner ear mechanoreceptors convert sound vibrations into electrical signals.
What are hair cells?
Unlike all other sensory systems, olfaction bypasses this brain relay station.
What is the thalamus?
Tastebuds, made up of basal cells, columnar cells, and 10-50 taste receptor cells are renewed this many days.
Every 9-10 days
These receptors are sensitive to changes in internal bodily conditions like blood pressure.
What are interoceptors?
This structure is the eye’s outermost layer and begins focusing incoming light
What is the cornea?
This part of the inner ear helps maintain equilibrium by detecting rotational head movements.
What are the semicircular canals?
Olfactory receptor neurons send signals to this brain structure before reaching the cortex.
What is the olfactory bulb?
Repeated exposure to sweet and salty foods may lead to this kind of receptor change.
What is down-regulation?
These receptors sense stimuli that arise in the external environment.
What are exteroceptors?
