MICROANATOMY

Detailed explanation-1: -Your medulla oblongata is the bottom-most part of your brain. Its location means it’s where your brain and spinal cord connect, making it a key conduit for nerve signals to and from your body. It also helps control vital processes like your heartbeat, breathing and blood pressure.

Detailed explanation-2: -The brain stem sits beneath your cerebrum in front of your cerebellum. It connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate and blood pressure.

Detailed explanation-3: -The respiratory center is located in the medulla oblongata and is involved in the minute-to-minute control of breathing. Unlike the cardiac system, respiratory rhythm is not produced by a homogeneous population of pacemaker cells.

Detailed explanation-4: -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-5: -The pontine respiratory group of neurones (once known as the pneumotaxic centre) is responsible for the ‘fine-tuning’ of our breathing and for preventing overinflation of the lungs. It achieves this by sending constant inhibitory impulses to the inspiratory centre in the medulla to limit the period of inspiration.
