electrochemicals are __________ from real world energy into nerve impulses the brain can interpret

those receptors that maintain their higher firing rate the whole time that a stimulus is applied are ________ receptors

________ receptors alert us to changes in sensory stimuli but decrease their firing rate (sensory adaptation)

to cease paying attention to constant stimuli is ______________

the law of specific nerve energies is that the adequate stimulus requires ____________

the increasing amplitude of ___________ increases the frequency of action potentials (respose to stimulus)

sensory adaptation would occur in __________ and __________ receptors

pathway of somatesthetic senses: skin > 2nd order neuron to _________ > 3rd order input to _____________ cortex

unmyelinated dendrites for touch, cold, hot, pain are _________

__________ is when pain receptors synapse with the same neurons as other body areas and cause sensations in undamaged tissue (i.e. heart attack / left arm)

the smaller the two point touch threshold, the _________________ sensitivity of the area

sharping of sensation at point of touch and dulling neuron sensation around the peripheral area is _________

salty taste: ____+ and Ca+ cause depolarization

Sour taste: ___+ and Ca+ cause depolarization

Sweet & umami Taste: sugars and G-protein close ____+, leading to depolarization

Bitter taste: quinine binds with G-protein and __+ causing depolarization

odorant molecules depolarize a neuron by binding G-protein and cyclic AMP which open ___ and ___ channels

_________ senses are paired with the limbic system

olfactory neurons are bipolar and extend into the nasal cavity. They connect with other things like glomeruli in the __________

the vestibular apparatus and the ___________ form the inner ear

the utricle, saccule, and the semicircular canals are parts of the __________
