Flashcards in Chapter 8 Deck (26):
(1)Adaption in response to differences or changing needs; (2)Adjustment of the eye for seeing objects at close range.
Area on the retina without receptors that respond to light. Images that fall on this region are NOT seen. Optic nerve exits the eye on its way to the brain in this region.
Receptors sensitive to various chemicals in solution.
The pigmented nutritive layer of the eye.
Structure in the eye that releases a transparent liquid called aqueous humor within the eye. Includes ciliary muscle, which control shape of the lens.
A cavity of the inner ear resembling a snail shell; houses the hearing receptor.
The transparent anterior portion of the eyeball.
Sensory organ of rotation located in the semicircular canal of the inner ear. Senses angular acceleration and deceleration.
Sense that reports on angular or rotatory movements of the head in space.
The pigmented, involuntary muscle that acts as the diaphragm of the eye.
Bony cavities and membranes of the inner ear that house the hearing and equilibrium receptors.
The elastic, doubly convex structure in the eye that focuses the light entering the eye on the retina.
Small and highly sensitive part of the retina responsible for detailed central vision.
Receptors sensitive to mechanical pressures such as touch, sound, or contractions.
Organ of Corti
The receptor organ for hearing and is located in the mammalian cochlea.
The three bones of the middle ear: hammer, anvil, and stirrup.
Specialized receptor cells that respond to light energy.
The bending of light.
Light sensitive layer of the eye; contains rods and cones.
The firm white fibrous outer layer of the eyeball; protects and maintains eyeball shape.
Part of inner ear. Lined with cilia and filled with endolymph fluid. Serve as body's balance organ.
Balance concerned with changes in the position of the head.
Receptors for taste on the tongue, roof of mouth, pharynx, and larynx.
