MEDICAL PHYSIOLOGY

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 brain controls the heart directly through the sympathetic and parasympathetic branches of the autonomic nervous system, which consists of multi-synaptic pathways from myocardial cells back to peripheral ganglionic neurons and further to central preganglionic and premotor neurons.

Detailed explanation-4: -The Medulla 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. The dorsal respiratory group stimulates inspiratory movements.

Detailed explanation-5: -The respiratory center is located in the medulla oblongata and is involved in the minute-to-minute control of breathing.
