Receptors and Senses
These structures detect changes in the internal or external environment.
Sensory Receptors
These receptors detect pain.
Nociceptors
This transparent structure bends incoming light first.
Cornea
This membrane vibrates when struck by sound waves.
Tympanic Membrane (eardrum)
These structures detect dissolved chemicals in food.
Taste buds
This is the awareness of a stimulus.
Sensation
These receptors detect temperature.
Thermoreceptors
The pupil controls this.
The amount of light entering the eye
Malleus, incus, and stapes are collectively known as these.
Auditory ossicles
Sweet, sour, salty, bitter, and this taste make up the five primary tastes.
Umami
This is the interpretation of sensory information by the brain.
Perception
These receptors detect touch, pressure, and vibration.
These photoreceptors provide vision in dim light.
Rods
This structure contains the organ of Corti.
Cochlea
These structures contain taste buds on the tongue.
Papillae
Processes sensory information
Brain and Spinal Cord
These receptors help you know where your body parts are without looking.
Proprioceptors
These photoreceptors are responsible for color vision.
Cones
The organ of Corti contains these sensory cells.
Hair cells
These receptors detect airborne chemicals.
Olfactory Receptors (Chemoreceptors)
Nociceptors, thermoreceptors, mechanoreceptors, chemoreceptors, and photoreceptors are examples of these.
Pain felt in the left arm during a heart attack is an example of this phenomenon.
Referred Pain
This retinal region provides the sharpest vision.
Fovea centralis
These structures detect rotational or angular acceleration.
Semicircular Canals
Smell is strongly linked to emotion because of connections to this part of the brain.
