unit 4a: senory stuff Flashcards
the dimension of color determined by wavelength
hue
the amount of energy in a wave
intensity
adjustable opening in the center of the eye where light enters
pupil
transparent structure behind the pupil that changes shape to help focus on images
lens
inner surface of the eye, containing receptor rods and cones plus layers of neurons that begin info processing
retina
retinal receptors that detect shades of gray, necessary for peripheral and twilight vision
rods
concentrated in the center of the retina and function in well-lit conditions, detect fine detail and color
cones
the nerve that carries neural impulses from the eye to the thalamus
optic nerve
the central focal point in the retina, around which the eye’s cones cluster
fovea
stimulus energy turning into neural impulses
transduction
the conversion of light energy into neural impulses
phototransduction
a tone’s experienced high or lowness
pitch
chamber between the eardrum and the cochlea with three tiny bones that concentrate vibrations into the cochlea’s oval window
middle ear
a coiled, bony, fluid filled tube in the inner ear, fluid within triggers neural impulses with waves
cochlea
caused by damage to the cochlea’s cillia or to auditory nerves
sensorimotor hearing loss
