Why does the diaphragm and relax when you breath?
The dipahragm is innervated by the phrenic nerve. This nerve responds to the stimulus sent by the a very particular set of neurons located in the medulla. The main ones are called VRG and DRG. Of these the VRG sends signals to the diaphragm to contract, when the signal is not "on" then the diaphragm relaxes. DRG modulates the depth of breath. There is another group called the pneumotaxic center found in the ponds; this group keeps the VRG in check. If the frequency of respiration becomes too great the pneumotaxic center inhibits depolarization of the VRG for a while in an attempt to restore a "normal" breathing pattern
Which part of the brain controls forceful breathing?
Ventilation occurs under the control of the autonomic nervous system from parts of the brain stem, the medulla oblongata and the pons. This area of the brain forms the respiration regulatory center, a series of interconnected brain cells within the lower and middle brain stem which coordinate respiratory movements. The sections are the pneumotaxic center, theapneustic center, and the dorsal and ventral respiratory groups. This section is especially sensitive during infancy, and the neurons can be destroyed if the infant is dropped and/or shaken violently. The result can be death due to "shaken baby syndrome".
Where in the body does respiration happen?
In the lungs. That's where gas exchange and respiration takes place
What is at the center of any self-respecting volcano?
An epicentre in a volcano is where the whole volcano erupted and when the primary and secondary effects started
What are each part of cell and its job?
There are many parts of the cell. The nucleus is the control center for all activity. The cell membrane separates the cell from other cells. The mitochondria is the center of respiration of the cell. Vacuoles are clear fluid sacs that act as storage for food, waste, and minerals.
Where is the pneumotaxic center and the apneustic center located?
in the pons
What center is located in the pons?
pneumotaxic pontine respirator group (PRG)
What is the function of the pneumotaxic center of the pons?
The pneumotaxic center of the pons helps regulate the pattern and rate of breathing by controlling the duration of inspiration and expiration. It works in coordination with the respiratory center in the medulla to ensure proper breathing rhythm.
What happens if the neural connections between the pneumotaxic center and apneustic center are severed?
Decreased pulmonary and alveolar ventilation.
Breathing is controlled by what part of the brain?
There are four main centers in the brain to regulate the respiration: 1. Inspiratory center 2. Expiratory center 3. Pneumotaxic center 4. Apneustic center The first two centers are present on the medulla oblongata whereas the last two centers on the pons region of brain.
What function does the pneumotaxic center serve?
The pneumotaxic center is aka pontine respiratory group (PRG). Its function is to inhibit inspiration, regulating inspiratory volume and rate. It can be considered an antagonist to the apneustic center which produces abnormal, deep, prolonged inspiratory gasps. Both of these structures are found in the pons of the midbrain.
What center is located in pons?
pneumotaxic pontine respirator group (PRG)
What region of the brain controls the breathing rate?
the nucleus tractus solitarus (basic control) of the medulla along with the pneumotaxic center of the pons (fine control)

Location of respiration center?
I think it's in the brain.
What is part of cell that serves as center of respiration?
mitochondria.
