The respiratory centers which control involuntary breathing rates are in the medulla and pons.
No, breathing is not voluntary. We breathe because we need to and we don't think about it. If we didn't breathe we would be dead, so it is an involuntary action. Breathing is unique in that you can temporarily control it, but most of the time breathing happens without thinking.
Respiratory control centers are located in the brainstem, specifically in the medulla oblongata and pons. These centers regulate the rate and depth of breathing by monitoring levels of oxygen, carbon dioxide, and pH in the blood.
The brain stem is divided into three section known as: midbrain, pons, and medulla oblongatta. The medulla is referred to as the cardiac and respiratory centers of the body. It is in the medulla oblongatta that the basic control of the external respiration that occurs in the lungs. The medulla sends a signal via the phrenic nerve that control the involuntary portion of breathing. Breathing is a process that is unique in the body in that it is controlled both by voluntary and involuntary mechanisms.
The respiratory control centers in the brain are primarily located in the medulla oblongata and pons, which are part of the brainstem. These regions regulate the rate and depth of breathing to maintain appropriate levels of oxygen and carbon dioxide in the body.
Breathing is governed by the respiratory centers in the brainstem, specifically the medulla oblongata and pons. Reflexes are controlled by neural pathways that involve the spinal cord and brainstem, allowing for rapid and involuntary responses to stimuli without conscious control.
Involuntary muscles control functions like breathing and digestion.
Breathing is both a voluntary and involuntary action. We can control our breathing consciously, but it also happens automatically without us having to think about it.
it does so by determining how acidic the bloodis. if it has a low pH due to large abount of co2 in the blood then you breath more. if you have lots of oxygen and a higher pH then you breathe slower. this hapens in the cerabelum.
Respiratory control centers are located in the medulla and the pons. In the medulla the ventral respiratory group contains rhythm generators whose output drives respiration. Also in the medulla, the neurons of the dorsal respiratory group integrate peripheral sensory input and modify the rhythms generated by the VRG. The pons respiratory centers interact with the medulla centers to smooth the breathing pattern. The respiratory center (RC), itself, is located in the medulla oblongata, the lowermost portion of the brainstem.
The diaphragm is a skeletal muscle that separates the thoracic and abdominopelvic cavities. It is innervated by the phrenic nerve. The diaphragm is the main muscle of respiration, with diaphragmatic contraction responsible for 75% of the air movement in a normal breath at rest. Respiratory control is both voluntary and involuntary. Because of the involuntary control, the diaphragm is commonly mistaken to be made up of smooth muscle, but this is incorrect. The brain's involuntary respiratory centers regulate the activity of the diaphragm and intercostal muscles in response to sensory information (very much like an involuntary reflex arc). These involuntary centers are housed in the brainstem. The cerebral cortex controls voluntary breathing, which also affects the diaphragm and intercostal muscles. For forced inhalation or exhalation, additional skeletal muscles (e.g., pectoralis minor, scalenes, sternocleidomastoid) may also be involved.

When activated, the breathing control centers increase the rate of nerve impulses to the diaphragm and intercostal muscles. This causes these respiratory muscles to contract and expand the thoracic cavity, allowing air to flow into the lungs. By adjusting the rate and depth of breathing, the body can regulate oxygen and carbon dioxide levels in the blood.
