Your medulla oblongata is located at the base of your brain, where the brain stem connects the brain to your spinal cord. It plays an essential role in passing messages between your spinal cord and brain. It’s also essential for regulating your cardiovascular and respiratory systems. What are the three functions of the medulla? The medulla oblongata carries signals from the brain to the rest of the body for essential life functions like breathing, circulation, swallowing, and digestion. What does the lower pons and medulla control? Components of the Brainstem The medulla oblongata (myelencephalon) is the lower half of the brainstem continuous with the spinal cord. Its upper part is continuous with the pons. The medulla contains the cardiac, respiratory, vomiting, and vasomotor centers regulating heart rate, breathing, and blood pressure. What does the medulla directly control? The medulla oblongata, also known as the medulla, directly controls certain ANS responses, such as heart rate, breathing, blood vessel dilation, digestion, sneezing, swallowing and vomiting. It is a portion of the brainstem, located just below the pons and just above the spinal cord. Read More: What is manufacturing pharmacy field?

A stroke involving the medulla can also interfere with your body's normal breathing and heart function. Some people who have this type of stroke may need a machine to breathe. More severe strokes in the medulla can cause "locked-in syndrome." This is a condition in which people are conscious but cannot move any part of the body except the eyes. • Severe headaches that start suddenly and get worse when you change positions, bend, strain, or cough • Double vision • Numbness in the arm, face or leg on one side • Weakness of the face, arm or leg on one side • Dizziness • Difficulty walking • Loss of balance or coordination • Persistent hiccups • Loss of consciousness • Kim K, Lee HS, Jung YH, et al.

• Median fissures: Shallow groves located along the anterior and posterior portions of the medulla. • Olivary bodies: Paired oval structures on the medulla's surface that contain nerve fibers connecting the medulla to the pons and cerebellum. Olivary bodies are sometimes called olives. • Pyramids: Two rounded masses of • Fasciculus gracilis: A continuation of the bundle of nerve fiber tracts that extend from the spinal cord to the medulla. Damage to the Medulla Injury to the medulla oblongata may result in a number of sensory-related problems. Non-fatal complications include numbness, paralysis, difficulty swallowing, acid reflux, and lack of motor control. But because the medulla also controls vital autonomic functions such as breathing and heart rate, damage to this area of the brain can be fatal. Drugs and other chemical substances can impact the medulla's ability to function. An opiate overdose can be deadly because these drugs inhibit medulla activity until the body can't regulate essential functions. Sometimes, the medulla oblongata's activity is intentionally and very carefully suppressed. For example, the chemicals in anesthesia work by acting on the medulla to decrease autonomic activity. This results in a lower breathing and heart rate, relaxation of muscles, and loss of consciousness.​ This makes surgery and other medical procedures possible. Bailey, Regina.

The hindbrain is located at the lower back part of the brain and includes most of the brainstem (containing the medulla and pons), and the cerebellum. The hindbrain is located at the back of the head and looks like an extension of the spinal cord The hindbrain is also known as the rhombencephalon and is one of the most crucial parts of the central nervous system (CNS) as it connects the brain to the spinal cord so that messages can be sent from the brain, down the spinal cord, to the rest of the body. The hindbrain is essentially an extension of the spinal cord, with tracts of axons running through the spinal cord to the hindbrain, which integrates the incoming sensory information and coordinates motor responses. The hindbrain’s chief role is to coordinate the vital functions of our bodies, such as breathing and heart rate. Therefore, the hindbrain is important for survival. Another main function of the hindbrain is the organization of motor reflexes, mostly controlled by the The pons comes from the Latin word for bridge, named so, as it essentially forms a bridge from the brainstem to the The pons is situated right underneath the midbrain and serves as the coordination center for signals which flow between the two cerebral hemispheres and the spinal cord. This structure is strongly associated with many autonomic functions, such as breathing, taste, sleeping, and circuits that generate respiratory rhythms. The pons is also involved in analyzing sensory data and is where au...
