BIOL 373L STUDY SET
Sensory cells - correct answer ✔✔respond to factors such as light pressure and the chemical nature of
certain molecules by creating electrical signals which are sent to the CNS
Visual acuity - correct answer ✔✔the degree of detail the eye can distinguish
myopia - correct answer ✔✔near lighted, light focuses in front of the retina, unable to see far, distant
objects are out of focus
hyperopia - correct answer ✔✔far sighted, hard to focus objects close to the eye
astigmatism - correct answer ✔✔the blurring or distortion of the visual image caused by a defective
curvature of the refractive surfaces of the eye
color blindness - correct answer ✔✔a diminished ability to sense color accurately
taste buds - correct answer ✔✔consist of barrel shaped groupings of sensory cells located on the tongue
and in the epithelial lining of the mouth
color blindness is caused by - correct answer ✔✔a deficiency in the retinas systems for converting red
blue of green light into receptor potentials
ichikawa color vision test - correct answer ✔✔measures the perception of color
tonic olfaction - correct answer ✔✔or slowly-adapting sensors produces a continuous sequence of AP as
long as the stimulus last
Phasic olfaction - correct answer ✔✔or rapidly adapting receptors detect a stimulus of constant
strength, send a stream of AP of steadily decreasing frequency to the CNS
, is the ear more efficient at detecting sound waves that are conducted through bone or air - correct
answer ✔✔air
Air conduction should be greater than bone conduction and so the patient should be able to hear the
tuning fork next to the pinna (outer ear) after they can no longer hear it when held against the mastoid.
during the RHinnes test
proprioceptors - correct answer ✔✔send sensory info to the brain regarding the tension of the skeletal
muscles and the positions of the limbs
the special senses are - correct answer ✔✔vision
taste
olfaction
hearing
equilibrium
reflex arc - correct answer ✔✔fundamental pathway linking sensory input and motor output
nerve cells in a monosynaptic reflex - correct answer ✔✔afferent (sensory) neuron
efferent (motor) neuron
cutaneous reflex- Babinski reflex - correct answer ✔✔elicited by stimulation of cutaneous receptors in
the sole of the foot, it is integrated not in the spinal cord, but in the brain
normal response causes flexion (down) of big toe while other toes flex and come together
pupillary light reflex - correct answer ✔✔reflex is consensual; the stimulus on one side produce a
response on both sides
corneal blink reflex - correct answer ✔✔consensual
menace reflex - correct answer ✔✔not controlled by higher centers
