Detailed explanation-1: -The medulla oblongata is the primary respiratory control center. Its main function is to send signals to the muscles that control respiration to cause breathing to occur. There are two regions in the medulla that control respiration: The ventral respiratory group stimulates expiratory movements.

Detailed explanation-2: -In sum, RTN neurons regulate alveolar ventilation by controlling breathing rate, inspiratory amplitude, active expiration and airway patency. These effects are mediated via axonal projections to unidentified neurons located within four respiratory-related lower brainstem regions.

Detailed explanation-3: -The respiratory center is located in the medulla oblongata and is involved in the minute-to-minute control of breathing.

Detailed explanation-4: -Breathing is an automatic and rhythmic act produced by networks of neurons in the hindbrain (the pons and medulla). The neural networks direct muscles that form the walls of the thorax and abdomen and produce pressure gradients that move air into and out of the lungs.

Detailed explanation-5: -Involuntary respiration is under subconscious control. The diaphragm and intercostal muscles are the primary respiratory muscles. They are stimulated by groups of neurons located in the pons and medulla.
