| 词条 | Ventrolateral medulla |
| 释义 |
The ventrolateral medulla in the medulla oblongata of the brainstem, plays a major role in regulating arterial blood pressure. It does this by regulating the activity of the sympathetic nerves that target the heart and related blood vessels. The ventrolateral medulla consists of a rostral ventrolateral medulla (RVLM) and a caudal ventrolateral medulla (CVLM).[1] Neurons in the RVLM project directly to preganglionic neurons in the spinal cord and maintain tonic activity in the sympathetic vasomotor nerves. This activity is inhibited by GABA output from the CVLM.[2][3] References1. ^{{cite journal |last1=Campos |first1=RR |last2=Carillo |first2=BA |last3=Oliveira-Sales |first3=EB |last4=Silva |first4=AM |last5=Silva |first5=NF |last6=Futuro Neto |first6=HA |last7=Bergamaschi |first7=CT |title=Role of the caudal pressor area in the regulation of sympathetic vasomotor tone. |journal=Brazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologicas |date=July 2008 |volume=41 |issue=7 |pages=557-62 |pmid=18719736}} 2. ^{{cite journal |last1=Dampney |first1=RA |last2=Horiuchi |first2=J |last3=Tagawa |first3=T |last4=Fontes |first4=MA |last5=Potts |first5=PD |last6=Polson |first6=JW |title=Medullary and supramedullary mechanisms regulating sympathetic vasomotor tone. |journal=Acta physiologica Scandinavica |date=March 2003 |volume=177 |issue=3 |pages=209-18 |doi=10.1046/j.1365-201X.2003.01070.x |pmid=12608991}} 3. ^{{cite journal |last1=Sved |first1=AF |last2=Ito |first2=S |last3=Madden |first3=CJ |last4=Stocker |first4=SD |last5=Yajima |first5=Y |title=Excitatory inputs to the RVLM in the context of the baroreceptor reflex. |journal=Annals of the New York Academy of Sciences |date=June 2001 |volume=940 |pages=247-58 |pmid=11458682}} 4 : Sympathetic nervous system|Reflexes|Medulla oblongata|Cardiovascular physiology |
