Behavioral Science 2.4 Flashcards
Olfactory chemo receptors
Located in the olfactory epithelium specific chemicals and particles find to the chemo receptors to recognize different scents
Pheromones
Excreted chemicals detected by smell exhibit a role in social interaction
Olfactory pathway
Particles, receptors, olfactory bulb, olfactory tracks, then brain
Taste chemo receptors
Sensitive to dissolve compounds
Taste pathway
Particles, chemo receptors in the taste buds, taste buds or in papillae, Nerve signal is sent to the brain stem, signal is sent to the taste center in the thalamus
Somatosensation
The sense of touch including pressure, vibration, pain, and temperature
Pacinain corpuscles
Response to deep pressure and vibration
Meissner Corpuscles
Light touch response
Markell cells
Response to deep pressure and texture
Ruffini endings
Response to stretch
Free nerve endings
Response to pain and temperature
Somatosensory pathway
Cells, CNS, somatosensory cortex in the parietal lobe
Two point threshold
The minimum distance between two points to distinguish two from one stimuli
Physiological zero
Temperature is below or above skin temperature feel cold or warm
Gate theory of pain
There is a mechanism that turns pain signals on or off affecting whether we perceive them.
