Which one of the following is NOT a respiratory center which regulates breathing in human?
Options
- AApneustic center in the medulla.
- BDorsal group of neurons in the medulla.
- CVentro-lateral group of neurons in the medulla.
- DPneumotaxic center in the pons.
Correct answer
A. Apneustic center in the medulla.
Step-by-step solution
The respiratory centers that regulate breathing in humans are located in the medulla oblongata and the pons of the brainstem.
The medulla oblongata contains the respiratory rhythm center, which consists of the dorsal respiratory group (DRG) of neurons and the ventral respiratory group (VRG) of neurons.
The pons contains the pneumotaxic center and the apneustic center, which moderate the functions of the respiratory rhythm center.
Since the apneustic center is located in the pons and not in the medulla, the statement 'Apneustic center in the medulla' is incorrect.
Answer: Apneustic center in the medulla.
