A) pontine respiratory group
B) ventral respiratory group
C) dorsal respiratory group
D) pre-Botzinger complex

Accepted Answer

The nucleus tractus solitarius in the medulla oblongata contains the dorsal respiratory group of neurons, which are involved in the regulation of respiratory rhythm and pattern. The pontine respiratory group is located in the pons and is involved in modifying respiratory activity, while the ventral respiratory group and pre-Botzinger complex are also located in the medulla oblongata and play roles in respiratory control.
