BIOL 1080 Lecture Notes - Lecture 19: Chronotype, Homeostasis, Hypothalamus
Document Summary
Slide 1b: homeostasis is always about a range of values (35. 4 to 37. 8 c, example: modern pulse furnace. Slide 2a: at a given set point, you get a range of temperatures at over a 40-minute period you might feel warm or cool several times. Slide 2b: shows negative feedback diagram, homeostasis follows the negative feedback loop. Slide 3a: both would have their own negative feedback loops. Slide 3b: blue cool red- hot, shows furnace negative feedback. Slide 4b: there is at least one coordinating center, there is at least 4 ways to affect body temperature (we have behavioural adaptation ex. move away from fire to decreases temperature) Slide 5b: this graph represents average chronotype. Slide 6a: answer to question: maybe, but comfort is a learned preference, diagram shows temperature decreases as age increases. Slide 6b: answer to question: very complex question, no simple answer. Slide 7b: real life challenges are multi-dimensional.
