Sensation

Question 1

sensation

Answer 1

The process of detecting the presence of stimuli.

Question 2

perception

Answer 2

The higher-order process of integrating, recognizing, and interpreting complex patterns of sensations.

Question 3

cons

Answer 3

The visual receptors in the retina that mediate high acuity color vision in good lighting.

Question 4

rods

Answer 4

The visual receptors in the retina that mediate achromatic, low acuity vision under dim light.

Question 5

transduction

Answer 5

The conversion of one form of energy to another.

Question 6

COMPONENT THEORY

Answer 6

The theory that the relative amount of activity produced in three different classes of cones by light determines its perceived color (also called trichromatic theory).

Question 7

OPPONENT-PROCESS THEORY

Answer 7

The theory that a visual receptor or a neuron signals one color when it responds in one way (e.g., by increasing its firing rate) and signals the complementary color when it responds in the opposite way (e.g., by decreasing its firing rate).

Question 8

ORGAN OF CORTI

Answer 8

The auditory receptor organ, comprising the basilar membrane, the hair cells, and the tectorial membrane.

Question 9

TASTE BUDS

Answer 9

Cluster of taste receptors found on the tongue and in parts of the oral cavity.

Question 10

OLFACTORY MUCOSA

Answer 10

The mucous membrane that lines the upper nasal passages and contains the olfactory receptor cells.

Question 11

FREE NERVE ENDINGS

Answer 11

Neuron endings that lack specialized structures on them and that detect cutaneous pain and changes in temperature.

Question 12

VESTIBULAR SYSTEM

Answer 12

The sensory system that detects changes in the direction and intensity of head movements and that contributes to the maintenance of balance through its output to the motor system.

Question 13

SEMICIRCULAR CANALS

Answer 13

The receptive organs of the vestibular system.
