Studied by 4 people
pain sensivity
Increased ________ after injury- occurs at injury site as well as CNS gate.
Perception
the more complex organizing of sensory information within the brain and the meaningful interpretations extracted from it.
receptor cells
Most mammals have a vomeronsal organ which contains ________ specialized for responding to pheromones.
Pitch perception
the aspect of hearing that allows us to tell how high or low a given tone is.
neural impulses
Can trigger ________ in taste sensory neurons, which send input to the primary taste ares in the frontal lob and other parts of the brain.
Salt
balances bodily fluids, sugar provides energy, protein builds tissues.
Mekxack and Walls Gate- Control Theory of Pain
Pain depends on the degree to which pain input can pass through a gate to the CNS that enters the brain stem.
Pinna
a flap of skin and cartilage forming the visible portion of the ear.
Odorants
a substance giving off a smell, can enter through the nostrils or the mouth.
Psychophysics
the study of relationships between physical characteristics stimuli and sensory experience produces by those stimuli.
Rods
insensitive to color, mostly responsible for peripheral vision and mission at night.
Somatosense
we experience pain coming from our bodies, not the world.
Nasopharynx
opening in the back of the mouth which connects the nasal cavity.
Nociceptors
free nerve endings of pain sensory neurons located in many parts of the body.
Flavor
consists of true taste as well as smell.
Pheromone
a chemical substance that is released by an animal, and acts on their members of its species promote some specific behavioral or psychological response.
Cones
color sensitive, respoible for clear vision.
Mother infant bonding
both mothers and newborns can identify each other based on smell alone.
unpleasant tastes
Generally, pleasentant and ________ correlate to nutritional and non- nutritional foods for our ancestors living in more natural, non- sedentary, environments.
Sensory receptors
specialized structures that respond to physical stimuli by producing electrical changes that can initiate neural impulses in sensory neurons.
Sensory adaptation
the change in sensitivity that occurs when a given set of sensory receptors and neurons is either strongly stiulayted or relatively unstiulated for a length of time.
Absolute threshold
the faintest debatable stimulus of any types of stimulus.
Olfactory epithelium
contains roughly 6 mil olfactory sensory neurons.
Physical stimulus
the matter of energy of the physical world that impinges on sense organs.
Sensation
the basic processes by which sensory organs and nervous system respond to stimuli in the environment and the elementary psychological experiences that result from these processes
Perception
the more complex organizing of sensory information within the brain and the meaningful interpretations extracted from it
Physical stimulus
the matter of energy of the physical world that impinges on sense organs
Sensory receptors
specialized structures that respond to physical stimuli by producing electrical changes that can initiate neural impulses in sensory neurons
Sensory neurons
spec lined neurons that carry information from sensory receptors into the central nervous system
Sensory Transduction
when a receptor cell produces an electrical charge in response to physical stimulation
Sensory adaptation
the change in sensitivity that occurs when a given set of sensory receptors and neurons is either strongly stiulayted or relatively unstiulated for a length of time
Olfactory epithelium
contains roughly 6 mil olfactory sensory neurons
Mother-infant bonding
both mothers and newborns can identify each other based on smell alone
Choosing a genetically compatible mate
many species prefer a mate that smells most opposite of them
Pheromone
a chemical substance that is released by an animal, and acts on their members of its species promote some specific behavioral or psychological response
Odorants
a substance giving off a smell, can enter through the nostrils or the mouth
Nasopharynx
opening in the back of the mouth which connects the nasal cavity
Flavor
consists of true taste as well as smell
Somatosense
we experience pain coming from our bodies, not the world
Nociceptors
free nerve endings of pain sensory neurons located in many parts of the body
Free nerve endings
sensitive nerve terminals throughout the body
C fibers and A-delta fibers
two types of pain sensory neurons mediate two different waves of pain
Mekxack and Walls Gate-Control Theory of Pain
Pain depends on the degree to which pain input can pass through a gate to the CNS that enters the brain stem
Outer Ear
receives and funnels sound waves towards the structure where transduction occurs
Pinna
a flap of skin and cartilage forming the visible portion of the ear
Pitch perception
the aspect of hearing that allows us to tell how high or low a given tone is
Conduction deafness
ossicles become rigid and cannot carry sounds inward from the tympanic membrane to the cochlea
Receptors
130 million photoreceptors embedded in your retina
Rods
insensitive to color, mostly responsible for peripheral vision and mission at night
Cones
color sensitive, respoible for clear vision
Psychophysics
the study of relationships between physical characteristics stimuli and sensory experience produces by those stimuli
Absolute threshold
the faintest debatable stimulus of any types of stimulus
Difference threshold
the minimal difference in magnitude between two stimuli that is required for the person to detect them as different
