THE SENSORY ORGANS Flashcards
Nerve endings that respond to particular stimuli
Sensory Receptors
Mechanoreceptors
Respond to physical stresses in the form of touch, pressure, stretching, sound waves & motion
Thermoreceptors
Respond to changes in temperature
Chemoreceptors
Respond to chemical stimuli
Photoreceptors
Respond to light stimuli
The skin contains receptors that respond to touch, pressure, pain, & temperature
Skin Sense
What receptor is the skin sense?
Mechanoreceptor
what receptor is the olfactory sense?
Chemoreceptor
What receptor is the gustatory sense?
Chemoreceptor
What receptor has the sense of vision?
Photoreceptor
What receptor has the sense of hearing?
Mechanoreceptor
Photoreceptors that allow for sight in color
Cones
The clear dome covering the front of the eye
Cornea
Gives color to your eyes
Iris
A crystalline structure located behind the iris that focuses light on the retina
Lens
Nerve that transmits electrical impulses from the retina to the brain
Optic Nerve
the opening in the center of the iris, a hole that changes sizes
Pupil
Sensory tissue that lines the back of the eye that contains millions of photoreceptors
Retina
Photoreceptors that pick up black and white, used in night vision
Rods
Transparent liquid that helps keep the shape of the eye
Vitreous Humor
The white of the eye
Sclera
Watery fluid
Aquaeous Humor
Produces sharper vision with its cones & few rods
Macula
Is the pit inside the macula with only cones, so vision can be at its sharpest
Fovea
Front part of the eye between the cornea and the iris.
Anterior chamber
Is between the iris and lens
Posterior Chamber
Is between the lens and the back of the eye
Vitreous Chamber
