ALSO CALLED EARWAX
CHOROID
FORMS MOST OF THE EYES VASCULAR LAYER AND CONTAINS MOST OF THE EYES BLOOD VESSELS
COCHLEA
A SPIRALED SHAPE CANAL IN THE INTERNAL EAR THAT CONTAINS THE HEARING RECEPTORS
CONJUNCTIVA
THE PROTECTIVE MUCOUS MEMBRANE THAT LINES THE INNER SURFACES OF THE EYELIDS AND COVERS THE ANTERIOR PORTION OF THE SCLERA OR THE WHITE OF THE EYE
CORNEA
A TRANSPARENT AREA ON THE FRONT OF THE OUTER LAYER OF THE EYE THAT ACTS AS A WINDOW TO LET LIGHT INTO THE EYE
EUSTACHIAN TUBE
AN OPENING OF THE MIDDLE EAR LEADING TO THE BACK OF THE THROAT THAT HELPS EQUALIZE AIR PRESSURE ON BOTH SIDES OF THE EAR DRUM
ALSO KNOWN AS THE AUDITORY TUBE
EXTERNAL AUDITORY CANAL
CANAL THAT CARRIES SOUND WAVES FROM THE ENVIRONMENT TO THE TYMPANIC MEMBRANE
ALSO KNOWN AS THE EXTERNAL ACOUSTIC MEATUS
GUSTATORY CORTEX
AN AREA OF THE BRAIN THAT IS RESPOSIBLE FOR INTERPRETING TASTE SENSATIONS BY INTREGATING INFORMATION FROM THE TASTE CELLS WITH OTHER INFORMATION TO PROVIDE A MORE COMPLETE INTERPRETATION
LABRINTH
THE CHAMBERS AND TUBES WITHIN THE TEMPORAL BONE THAT HOUSE THE RECEPTORS OF HEAING AND EQUIIBRIAM IT INCLUDES THE VESTIBIAL SEMICIRCULAR CANALS AND COCHLEA
LACRIMAL APPARATUS

LINGUAL PAPILAE

IS THE INNER LAYER OF THE EYE CONTAINS LIGHT SENSING PHOTORECEPTORS
SEMICIRCULAR CANALS
PORTION OF THE BONEY LABRYNTH THAT CONTAINS THE SEMICIRCULAR DUCTS WHICH CONTAIN RECEPTORS FOR EQUILIBRIAM EACH OF THE THREE CANALS IS POSITIONED AT RIGHT ANGELS TO THE OTHER TWO
SENSORY ADAPTION
A PROCESS IN WHICH THE SAME CHEMICAL CAN STIMULATE RECEPTORS ONLY FOR A LIMITED AMOUNT OF TIME IN RESPONSE TO A PROLONGED STIMULAS THE RECEPTOR CELLS DECREASE THEIR RATE OF NERVE IMPULSE CONDUCTION UNTIL THEY NO LONGER RESPOND TO THE SAME CHEMICAL ODOR
MEANING THE ODOR IS NO LONGER DETECTED

IT CONTAINS RECEPTORS FOR THE EQUILIBRIAM
