Question

Respiratory rhythm center is present:
A) Cerebrum
B) Cerebellum
C) Medulla
D) Pons

Answer 1

Hint: Consist of two correct answers, first one-the structure is like a long stem which makes part of the brainstem. To the Cerebellum it is partially inferior and anterior. The second one is the largest part of the brainstem, present above the modular and below the midbrain. It comprises nerves which function as a connection between the cerebrum and cerebellum

Complete answer:
- In the medulla oblongata and pons located in the brain stem, the respiratory center is usually composed of three major respiratory groups of neurons, two in the medulla and one in the pons.
- The dorsal respiratory group and the ventral respiratory groups are present in the medulla and the pontine respiratory group has two areas mainly known as the pneumotaxic center and the apneustic center.
- For generating and maintaining the rhythm of the respiration, the respiratory center is very important and also used for adjusting the homeostasis response of the physiological changes.
- In order to regulate the rate and depth of the building the respiratory center takes input from chemoreceptors, mechanoreceptors, the cerebral cortex, and the hypothalamus.
- If any type of injuries happens to the respiratory groups then it can cause various breathing disorders which may require mechanical ventilation associated with a poor prognosis.

Additional information:
The cerebrum - it is the uppermost part of the brain comprising two hemispheres split by a central Fissure. Also, the major lobes of the brain are present in the cerebrum which is responsible for receiving and giving meaning to information from the sense organ. It also helps in controlling the body.
The Cerebellum - is a major part of the hand brain present near the brainstem. It helps in coordinating voluntary movements. It also performs a number of functions such as motor skills such as balance, coordination, and posture.
So, the correct answer is, ”Medulla and Pons”.

Note:
- The pons and the medulla oblongata is responsible for generating the respiratory rhythm.
- Respiratory group of Neurons, two in the medulla, and one in the pons, these three make the respiratory center.
- The primary respiratory control center in the medulla oblongata. It performs the sending of signals to the muscles which in turn controls the respiration to cause breathing.
