PHYL2001 Lecture Notes - Lecture 11: Dorsal Respiratory Group, Ventral Respiratory Group, Control Of Ventilation
Document Summary
Ventilation is an automatic response- does not think i have to breathe and the muscles automatically control to inhale and exhale. We also have some sensory input= in the chemoreceptors- in the lungs automatic breathing control over our breathing activation of neurons and also the respiratory muscles to give the change in thoracic volume. Hence a change in pressure of alveoli. Change in pressure gradient- hence air into the lungs, or out of the lungs. Respiratory centres: dorsal respiratory group--- contains inspiratory neurons-> helps with inspiration and expiratory neurons generated in the medulla but. Bi-laterally pairs grooves- there is a lot of communication between the 2 sites do not act separately and we respond together. To get a synchronised response- so that they: the dorsal associated with the nucleus tractus solitarius (nts) The pre-botzinger complex and the dorsal respiratory. Dorsal respiratory group in the inspiratory area.
