Test 2 Flashcards
Sketch the 3 types of receptors and how they work
Stretch channels that let Na+ in when opened, chemoreceptors that work by activating Na+ channels with cAMP, and light detection channels that use rhodopsin with the hexagon thingy that straightens then kicks out to activate cAMP
What is spontaneous activity and how does it work
Na sub v1.5 channels open at -70 mv which are too far apart to cause an AP by themselves but can cause an AP from stimulus that would be just under threshold
What is range fractionation and what is the trade-off
See study guide. trade off is having higher acuity across a broad range but costs more cells to gain that acuity
What is sensory adaption and what is the trade off
See study guide. trade off is being able to rapidly detect any decrease in stimulus but inability to recognize actual amount of stimulus
What is signal averaging and what are some of the disadvantages of it
See study guide. Costs resources and space to make additional cells and its harder for a single sensory cell to induce another AP/sec

What is the difference between an agonist and an antagonist
agonist increases production while antagonist prohibits it
How does E affect kisspeptin affect GnRH
Kiss positive cells have less E receptors so when there is a lot of it, there is a lot of GnRH produced. Kiss negative cells have the normal amount of E so when E is low GnRH is decreased.
