Ventral Respiratory Group (VRG)
Ventral Respiratory Group (VRG) is a column of neurons located in the medulla oblongata of the brainstem. It is one of the primary components of the respiratory center that regulates breathing.
Pronunciation
- Ventral: /ˈvɛntrəl/

Etymology
- Ventral: Derived from the Latin word 'venter' meaning 'belly'.
- Respiratory: Derived from the Latin word 'respirare' meaning 'to breathe'.
