Section 1

Question Answer
Special organs that detect chemicals and closely related to smellTaste buds
The 3 sections of ogran for hearingOuter, Middle, Inner
Gathers and transmits vibrations to internal structuresTympanic membrane (eardrum)
Transmits and amplifies Sound Vibrations to the inner earMiddle ear
Air filled cavity within the Temporal bone of the skullMiddle ear
The middle ear contains auditory ossicles..what are theyMalleus, Incus, and Stapes
The 3 chambers that deal with communicatingCochlea (snail), Semicircular canals, and Vestibule
The cochlea functionHearing
The Semicircular canals functionEquilibrium
The Vestibule functionEquilibrium
memorize

Section 2

Question Answer
What happens firstSpecialized receptor cells respond to different frequencies of vibrations, Hair cells respond by releasing neurtransmitters, Auditory ossicles amplify and transmit vibrations, Sound waves enter External ear, Sound pressures cause tympanic membrane to produce vibrations, Neurotransmitters stimulate sensory neurons in Cranial nerve VIII, or Impulses travel along Cranial nerve to the Auditory cortex in the Temporal lobe for interpretation

What is responsible for static equilibriumVestibule
Senses the Position of Head when body is not movingVestibule
What is responsible for dynamic equilibrium and senses movement of the head and bodySemicircular canals
Rapid turning of head and body will stimulate what receptors in earHair cells
Photoreceptors are assisted by Accessory organs...Eyelids, lacrimal apparatus, and extrinsic ocular muscles
Interpretation of visual stimuli is done byVisual cortex of occipital lobes
What are the three layers of the eyeOuter layer-Cornea and Sclera. Middle layer-Ciliary body and Iris. Inner-Retina, Macula Lutea, and Optic disc.
memorize

Section 3

Question Answer
Helps to focus entering light and transparent due to lack of blood vesselsCornea
White portion of eye that protects the eyeScerla
Attachment site for extrinsic musclesScerla
Helps to focus and change the shape of lensCillary body
The color portion determined by the amount of distrubutedIris
The opening center that controls how much light comes inPupil
Where visual receptors and dense capillariesRetina
Where are visual images formedRetina
Sharpest vision area of retinaMacula Lutea
Visual part of optic nerve "blind spot"Optic disc
memorize

Section 4

Question Answer
Two types of photoreceptor modified neuronsRods and Cones
Which receptor determines light sensitivity Rods
How is color derterminedWhite light is separated into wavelenghts and produce a single color impression
What we actually see as color is termedColor Effect
When seeing a blue ball it appears blue becausethe eye reflects only blue and absorbs every color but blue
The color red is reflected because it absorbs all the wavelength in light exceptred
What color reflects all the colors back and none are absorbedwhite
What color none are absorbedblack
Light rays hit an object and the object absorbs certain wavelengths and reflects others is termedColor Effect
Responsible for the color in visionCones
Produce sharp imagesCones
3 color pigment in ConesRed, Green, Blue
memorize

Section 5

Question Answer
Certain colors that are sensitive to overlapOrange, White, and Black
Color pigment overlap of orangeRed is stimulated more
Color pigment overlap of whiteAll 3 sets are stimulated
Color pigment overlap of blacknone are stimulated
lacking conescolorblind
Can see upclose, but trouble seeing away objectsNearsightedness
Can see far, but not nearFarsightedness
The destroying of capillaries in RetinaDiabetes
