CSB346H1 Lecture Notes - Lecture 7: Peripheral Chemoreceptors, Central Chemoreceptors, Peripheral Nervous System
Document Summary
Csb346 lecture 7 notes peripheral and central oxygen sensing (march 5, 2013) Slide 1 peripheral and central oxygen sensing. Central chemoreceptors are the brain cells and the brain regions that are somehow able to taste. Co2 levels and then turn that into a meaningful respiratory signal. However, o2 sensing and how that affects breathing is complicated. It is complicated because the signal, unlike that for. Co2 detection, can vary immensely across developmental age, depending on how one has been experiencing levels of hypoxia (e. g. , low levels of o2). It changes in young animals, with age, during pathologies, etc. It is also complicated because a large component of o2 sensing is in the peripheral nervous system (e. g. , carotid bodies). We are going to focus on this branch of chemical regulation of breathing. In terms of peripheral chemoreceptors, it"s not possible to talk about how they work unless we consider both co2 and.
