-5 primary sensations: salty, sweet, sour, bitter & umami (taste of amino acids such as MSG)

Front 2

smell

Back 2

-odor molecules must be volatile
- bind to a receptor on an olfactory hair triggering the production of a second messenger
– opens the ion channels & creates a receptor potential
– Some odors stimulate nociceptors

Bulb cells form the axons of the olfactory tracts
– lead to temporal lobe, amygdala, hypothalamus
• emotional responses to odors
• cough, salivate, sneeze or vomit in response to odors

Front 3

Sound

Back 3

• Sound is any audible vibration of molecules
• Vibrating object pushes air molecules into eardrum (tympanic membrane) making it vibrate

Front 4

muscles that prevent damage to hearing when extra loud stimulus is experienced

Back 4

Tensor tympani and stapedius muscles

Front 5

what does localization of sound depend on?

Back 5

relative intensity and relative timing of sound waves reaching both ears

Front 6

visible light

Back 6

electromagnetic radiation with wavelengths from 400 to 750 nm

Front 7

conjunctiva

Back 7

Produce lubricating mucus that prevents eye drying

Front 8

cornea

Back 8

transparent covering of anterior surface of eyeball (low water content, no blood vessels)

Front 9

aqueous humor

Back 9

clear serous fluid filling area in front of lens (between lens and cornea)

Front 10

Glaucoma

Back 10

is due to blocked drainage of aqueous humor raising pressure in the eye and causing blindness

Front 11

rhodopsin

Back 11

• Visual pigment of the rod cells

Front 12

where does Conscious perception of visual images occur?

Back 12

in the primary visual cortex in the occipital lobes
