What is the Medulla Oblongata? The medulla oblongata is key to understanding how general anesthesia works. Damage to the medulla oblongata can result in the need for a ventilator or other supportive equipment to keep the body working. The medulla oblongata is part of the brainstem, which helps connect the brain to the spinal cord.When life support is withdrawn from a person with catastrophic medulla oblongata damage, the body will cease to function.ou won't believe these 10 facts about people. The medulla oblongata is a structure found in the brains of vertebrate animals, including humans. This structure controls a number of autonomic functions, including respiration and blood pressure, making it a very critical part of the brain.

The Hindbrain: Definition, Structures & Function The hindbrain is the region of the brain formed by the pons, medulla oblongata (also known as just the medulla), and the cerebellum. Together, these three structures govern our autonomic, or 'automated' body systems, controlling everything from our heart, breathing, and sleep patterns to our bladder function, sense of equilibrium, and fine motor control.

In Anatomy, what is an Ampulla? The ampulla of the uterine tube is the middle part of the uterine tube in female humans. It is here that a woman's egg typically meets sperm if fertilization is to occur. The ampulla contains muscle and hair-like structures called cilia to help move a fertilized egg toward the uterus.An unfertilized egg, however, will degenerate in the ampulla. Ampullae also exist in other animals.t is here that a woman's egg typically meets sperm if fertilization is to occur.
