What is the medulla and what it does?
The medulla contains cranial nerves that regulate various functions in the body including the sensation in the oral cavity, swallowing, speech, and peristalsis movement. The medulla contains the respiratory center that includes the ventral respiratory center and dorsal respiratory center. They regulate the process of respiration.
What does the medulla regulate?
Why is injury to the medulla oblongata frequently fatal? Medulla houses vital reflexes centres like respiratory centre, cardiovascular, vasomotor. Injury results in death due to cessation of breathing, loss of BP & HR regulation
Why is injury to the medulla oblongata usually fatal?
The medulla oblongata connects our brain and our spinal cord with most of our sensory and motor fibres either crossing into the brain or finishing at this level (Farrell & Dempsey 2013). Damage to the medulla oblongata can result in: Difficulty swallowing. Loss of gag and cough reflex.

What is the function of the Medulla?
The medulla is primarily in charge of autonomous functions , most of which are involuntary. This means that they happen automatically without any thought. However, just because the medulla oblongata function doesn’t play a part in thinking doesn’t mean it isn’t interesting to psychologists.
What functions does the brain stem control?
In addition to the medulla, the brain stem has two other parts: the pons and the midbrain.
What happens if the Medulla Oblongata is damaged?
Damage to the medulla can cause slurred speech, difficulty swallowing, numbness in certain parts of the body, as well as paralysis.
What is the function of the Medulla Oblongata?
Thanks to the information obtained from baroreceptors in blood vessels, the medulla oblongata has the ability to regulate your blood pressure, blood acidity, and heart rate. In doing so, it also has the capacity to monitor and adjust the flow of blood to individual parts of the body.
What is the role of the Medulla in the body?
The medulla also plays a part in motor control and is essential for body movement coordination, head and shoulder movement, and speech.
What is the home of the respiratory system?
For one, the medulla is home to your body’s respiratory center.
What part of the brain controls mood?
The brain stem also works in tandem with other regions of the brain to control mood, enhance muscle movement coordination, regulate sleep, and organize sensory information. Finally, certain parts of the brain stem also play a role in hearing.
What happens if your medulla is damaged?
If your medulla is damaged, your brain and spinal cord won’t be able to effectively transmit information to one another.
What is the medulla oblongata?
Your medulla oblongata looks like a rounded bulge at the end of your brain stem, or the part of your brain that connects with your spinal cord. It also lies in front of the part of your brain called the cerebellum.
How do the cranial nerves communicate?
originate on this region. Your brain and spine communicate through columns of nerve fibers that run through your medulla called spinal tracts. These tracts can be ascending (send information toward your brain) or descending (carry information to your spinal cord).
What is the condition that affects the back portion of the brain?
Dejerine Syndrome. Dejerine syndrome or medial medullary syndrome is a rare condition that affects less than 1% of people who have strokes that affect the back portion of their brain. Symptoms include: weakness of the arm and leg on the opposite side of the brain damage.
What is Wallenberg syndrome?
Wallenberg syndrome is also known as lateral medullary syndrome. It frequently results from a stroke near the medulla. Common symptoms of Wallenberg syndrome include:
Where is the Medulla Oblongata located?
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.
Where is the medulla located?
Your medulla oblongata is located at about the same level or slightly above this hole. The top of your medulla creates the floor of the fourth ventricle of your brain. Ventricles are cavities filled with cerebral spinal fluid that help provide your brain with nutrients.
What nerve controls swallowing?
Cranial nerves three through eight begin in the midbrain and pons, and nerves nine through 12 begin in the medulla. Cranial nerve 9 is the glossopharyngeal nerve, and it controls swallowing, taste, and saliva production. Cranial nerve 10 is the vagus nerve, which plays a role in breathing, heart function, and digestion.
How long does it take for a medulla oblongata to form?
Made up of both white and gray matter, the cone-shaped medulla oblongata is formed about 20 weeks into gestation from the end of the neural tube in embryos. In adulthood, its functions are divided into sections, which each perform their own role. 2 .
What is the name of the condition where the medulla is paralyzed?
Medial Medullary Syndrome (Dejerine Syndrome): Caused by occlusion, or a blockage, in the vertebral or spinal artery, this condition results from a lack of blood blow through parts of the medulla causing paralysis in areas like the legs, arm, face, and possibly tongue.
What is the function of the Medulla Oblongata?
The medulla oblongata carries signals from the brain to the rest of the body for essential life functions like breathing, circulation, swallowing, and digestion. Making up a tail-like structure at the base of the brain, the medulla oblongata connects the brain to the spinal cord, and includes a number of specialized structures and functions.
Where is the Medulla Oblongata located?
These three collaborating structures are located in front of the cerebellum at the base of the brain and connect to the spinal cord. 1
What is the common form of stroke that affects the medulla?
Lateral Medullary Syndrome (Wallenberg Syndrome): This is the common form of stroke that affects the medulla. Caused by either a clot in the vertebral artery, or dissection of that artery, this syndrome can result in headache, pain, vertigo, trouble swallowing or speaking, and lack of sensation in the face.
Where does the brainstem work?
The work of the brainstem originates and is carried through the body by the cranial nerves.

Cranial nerves three through eight begin in the midbrain and pons, ...
