FOCUS HERE - Resp: Neural Regulation

Question 1

what are phrenic motoneurons? where are they found? what do they control

Question 2

where are the motorneurons driving the intercostal nerves found?

Question 3

when are inspiratory neurons most active?

Question 4

how do lung signals correspond with nerve signals

Question 5

which parts of the brain control resp rhythm

Question 6

describe the pathway from higher brain centers to primarily inspiratory muscles

Question 7

pathway from higher brain centers to exp, insp, pharynx, larynx, tongue muscles

Question 8

where is the pre botzinger complex?

Question 9

how are pre motor neurons and spinal cord related

Question 10

contrast activity timing of botzinger vs prebotzinger vs rostral

Question 11

contrast activity of hypoglossal vs phrenic

Question 12

how is prebotzinger related to resp muscles

Question 13

how can rhythmic breathing be influenced

Question 14

describe how resp motoneurons can be innervated.

Question 15

how can the the rhythm generator be innervated

Question 16

describe the feeback cycle regulating breathing (what do po2 and h activate? – what does this activate? what do airway and lung receps activate?)

Question 17

what is the difference between slowly adapting receptors and rapidly adapting receptors

Question 18

describe how RAR, SAR, baroreceps act in normal breathing
