brain stem respiratory centers

Fox 16.25 Approximate locations of the brain stem respiratory centers. The rhythmicity center in the medulla oblongata directly controls breathing, but it receives input from the control centers in the pons and from chemoreceptors.

延髄 medulla oblongata

　・　孤束核 solitary neucleus；ＤＲＧ（背側呼吸ニューロン群）；　←Ⅸ（carotid body）、Ｘ（気道[平滑筋の伸展受容器]、胸郭[肋間筋の筋紡錘]、肺胞[中隔のＪ受容器]、aortic body）　（味覚＋一般内臓感覚）

　・　疑核 ambiguous neucleus；ＶＲＧ（腹側呼吸ニューロン群）；　⇒C3-5[横隔膜], T1-11[肋間筋] 　（口蓋・咽頭・喉頭・食道の骨格筋）

呼吸中枢＝DRG+VRG；　⇒リズム形成
