Vision
The main visual pathway
Geniculostriate
Number of receptor types in the auditory system
One type of receptor
The perception of the location of one's body in space
Proprioception
The perception of fine touch
Hapsis
The perception of pain
Nociception
Part of the eye in which the photoreceptors are most densely packed
Fovea
Location of the auditory receptors
On the basilar membrane
Inability to accurately complete a plan of motor action
apraxia
A representation of the body in sensory and motor cortex
Homunculus
Axons that carry information about pain and temperature
Ventral spinothalamic tract
The phenomenon that occurs: when riding in a car, the trees and landscape appear to go backward as you peer out the window.
Optic flow
The order of the middle ear bones from the nearest to the eardrum to nearest to the oval window
Hammer, anvil, stirrup
Stimulates action potentials in the semicircular canals
bending hair cells
(a) Location of the primary somatosensory cortex
(b) Location of the secondary somatosensory cortex
(a) postcentral gyrus
(b) parietal lobeActivity in the hepatic-proprioceptive pathway can inhibit the pain pathway in the spinal cord
Gate theory of pain transmission
The pathway that conveys information to our internal clocks about the color blue
Retinohypathalamic pathway
Undulating displacement of air molecules caused by pressure changes
What creates sound waves
Causes muscle to relax
Absence of acetylcholine
Type of receptors that neurons in area 3B of the primary somatosensory cortex are responsive to
Slow-responding skin receptors
If a patient has a lesion on the RIGHT side of their spinal cord, just above their hips, what would they still be able to feel?
Pain in their right foot, light touch in their left foot
The primary visual relay nucleus in the thalamus
Lateral geniculate nucleus
Sounds with a single frequency
Pure tones
(a) Controls limbs and digits
(b) Controls mainly trunk muscles
(a) Lateral corticospinal tract
(b) Ventral corticospinal tract
Types of stimuli that pacinian corpuscles are most responsive to
Pressure and flutter stimuli
Names of 3 types of rapidly adapting receptors:
(1) Meissner corpuscles
(2) Pacinian corpuscles
(3) Golgi tendon organs
