ANATOMY

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 medulla oblongata is connected by the pons to the midbrain and is continuous posteriorly with the spinal cord, with which it merges at the opening (foramen magnum) at the base of the skull.

Detailed explanation-4: -The medulla oblongata connects directly to the heart through two different pathways: the vagus nerve and the accelerator nerve. The vagus nerve is part of the parasympathetic nervous system and it releases acetylcholine into the heart making it decrease the heart rate.

Detailed explanation-5: -Complete answer: A part of the brain that controls respiration, heartbeat and peristalsis is medulla oblongata.
