All Receptors
Sensory Receptors are specialized to respond to specific types of
Energy that stimulate them
The white of the eye
Sclera
The three main parts of the ear
Outer ear, middle ear, & inner ear
Olfaction is also known as
Sense of smell
Free nerve endings that detect temperature changes
Thermoreceptors
Sensory Receptors may be neuron endings or
Specialized receptor cells in close contact with neurons
The colored portion which makes up ones eye color
Iris
The inner ear is a boney labyrinth composed of
Cochlea, vestibule, and semicircular canals
Gustation is also known as
Sense of taste
Located in skin to respond to touch, pressure, & vibrations
Tactile Receptors
Sense Organs consist of
Sensory receptors (along with other types of cells)
The internal surface of the eye is covered by a black coat which prevents light rays from scattering
Choroid
Which parts of the ear are organs of equilibrium
Vestibule and semicircular canals
Taste is sensed by
Taste buds
Free nerve endings sensitive to stimuli that may be perceived as painful
Nociceptors
Sensory Adaptation is the decrease in frequency of
Action potentials in a sensory neuron even when the stimulus is maintained
The anterior cavity is filled with
Aqueous humor
Part of the ear which contains the Organ of Corti
Cochlea
Chemoreceptors in the the olfactory epithelium
Olfactory receptors
Occurs when the brain interprets an incoming message as coming from the body surface (not an internal organ)
Referred Pain
Sensory Adaptation results in
Decreased response to that stimulus
Rods and cones synapse on
Bipolar cells
The middle ear contains three main ossicles to amplify sound waves, know as
Malleus, incus, and stapes
Receptors which detects chemical substances in the air as well as in food and water
Chemoreceptors
Sensory neurons transmitting messages regarding painful stimuli secrete glutamate and
Substance P
