BIOL 3310 Lecture Notes - Lecture 5: Golgi Tendon Organ, Camillo Golgi, Forebrain
Document Summary
Absolute refractory- occurs during the ap, na+ channels inactive relative refractory- when k+ channels are still clear . Only a very strong stimulus can overcome this. Inner most stratum of center where photoreceptors are. Prosencephalon (forebrain ) (top on diagram)-telencephalon : cerebral hemisphere-diencephalon: hypothalamus & Monitor tautness in tendon -respond to tension a muscle put on a tendon. Area from one z line to the next. Focus on semblance vision -require higher light intensity. Respond to stimuli from outside of the body cutaneous: deliver info from the skin and include touch, temp. and nuisance special sense : ken , auditory sense , taste, scent. What is receptor voltage and how is it different from action potential? (generator electric potential )-stimuli prod. depolarizations(rp)-increasing pressure increment order of magnitude of the rp until threshold is met and action potential occurs. Respond at constant rate as long as stimulus is applied.
