Medulla Oblongata : The structure of the medulla oblongata


 What is Medulla Oblongata?

The medulla oblongata is the most vital part of the brainstem. It controls involuntary functions such as respiration and heart rate. It also contains important centers for coughing, swallowing, and vomiting.

The medulla oblongata is a cone-shaped neural structure located in the brainstem. It plays an important role in autonomic functions such as breathing, heart rate, and blood pressure. The medulla oblongata is also involved in many other functions, such as vomiting, hiccuping, swallowing, and sneezing.

List of nerves of the human body

The human nervous system is an amazingly complex network of nerve cells (neurons) that carry messages back and forth between the brain and spinal cord and the rest of the body. The nervous system is made up of the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which includes all the nerves that branch out from the brain and spinal cord.  The autonomic nervous system (ANS) is a part of the PNS that controls the body's involuntary functions, such as heart rate, blood pressure, digestion, and respiration.

The structure of the medulla oblongata in the human body

  • The medulla oblongata is a vital structure in the human body. It is located in the brainstem and is continuous with the spinal cord. The medulla oblongata controls many important functions such as respiration, heart rate, and blood pressure. It also contains important centers for reflexes such as coughing and swallowing.
  • The medulla oblongata is responsible for a variety of autonomic functions, such as respiratory rhythm, cardiovascular control, vomiting, and coughing. These functions are regulated by different groups of neurons that are located in distinct regions of the medulla oblongata. The respiratory rhythm generator is located in the ventral respiratory group, which is a cluster of neurons in the ventral half of the medulla. The cardiovascular control center is located in the cardioinhibitory and vasomotor centers, which are located in the dorsal half of the medulla.
  • Your medulla is an exceedingly crucial shape, but it’s additionally very small. It’s most effective, approximately 1.1 inches (three centimeters) long, and its widest diameter is just over 0.Seventy eight inches (2 centimeters) throughout.

Your medulla is beige or off-white with a slight red tint.

Like all different brain tissue, numerous types of white and gray mind are counted and nerve cells make up your medulla. The tissue of your mind is more or less:

  • 77% water.

  • 11% lipids (fats).

  • 8% proteins.

  • 4% different.

The average grownup human brain is between 2.6 and three.1 pounds, of which your medulla debts for about zero.Five%. That method your medulla weighs among 2 oz. And a couple of.Five oz (59 grams to seventy two grams).

What is the role of the medulla oblongata in the human body?

The medulla oblongata is a lower brainstem structure that serves as the control center for many vital autonomic functions, including respiratory and cardiovascular regulation. This small but important region is responsible for a variety of life-sustaining reflexes, such as coughing, sneezing, and vomiting. In addition, the medulla oblongata is involved in controlling blood pressure and heart rate. Although it is a small structure, the medulla oblongata plays a vital role in keeping the body functioning.

Some of its jobs encompass:

  • Manages heart, stream and breathing. Your medulla is in which your cardiovascular and breathing structures link together right into a united device that controls your heart rate, respiration, blood pressure and more.

  • Manages other automated techniques. These are things that your frame frequently does without you having to think about them. Some examples consist of coughing, sneezing, swallowing, vomiting and retaining your stability.

  • Nerve connections. The good sized majority of most important nerves converge at your backbone, carrying alerts to and from your mind. That approach those alerts have to bypass through your medulla. Four of your 12 cranial nerves (which connect regions of your throat and tongue directly for your mind) pass via your medulla.

  • Crossover factor. Your medulla is the place of a location referred to as “the pyramids,” where maximum of the movement-related nerves in your frame crisscross. That crossover is why one facet of your mind nearly usually controls components on the alternative facet of your frame.

Symptoms of the medulla oblongata in the human body

The medulla oblongata is a critical part of the brainstem. It is responsible for many involuntary actions of the body, such as breathing, heart rate, and blood pressure. Without the medulla oblongata, the body would not be able to function. There are many different symptoms that can arise when something goes wrong with the medulla oblongata.

Some of the maximum probable signs consist of:

  • Stroke signs.

  • Clumsiness or lack of coordination (symptoms of ataxia).

  • Headaches.

  • Hoarseness (dysphonia).

  • Inability to sense temperature or ache in part of your frame or face.

  • Jerky or uncontrolled eye movements (nystagmus).

  • Nausea and vomiting.

  • Paralysis (in numerous parts of your face or frame).

  • Trouble swallowing (dysphagia).

  • Vision troubles.

What affects the health of the medulla oblongata in the human body?

The medulla oblongata is an essential part of the brainstem that controls important involuntary functions like breathing and heart rate. It is also responsible for processing incoming sensory information from the spinal cord to the brain. Because of its central location and importance, the health of the medulla oblongata is essential to the overall health of the human body. There are many factors that can affect the medulla oblongata, including physical trauma, diseases, and disorders.

These consist of:

  • Aneurysms.

  • Cancer.

  • Concussion and demanding mind injuries.

  • Strokes or transient ischemic assaults (TIAs).

  • Other uncommon conditions encompass Moebius syndrome, multiple machine atrophy and innovative supranuclear palsy.

  • Wallenberg syndrome. Also called lateral medullary syndrome, this happens with an interruption in blood flow to a facet place of your medulla that damages that area. This is the maximum common sort of stroke that impacts your medulla.

  • Dejerine syndrome. Also referred to as medial medullary syndrome, this happens whilst a stroke cuts off blood drift to the center of your medulla, affecting the pyramids location wherein nerves crisscross.

  • Bilateral medial medullary syndrome. This is an unusual circumstance that combines the consequences of Dejerine syndrome and Wallenberg syndrome, affecting both aspects of your body.

  • Reinhold syndrome. This circumstance, additionally called hemi medullary syndrome, is extraordinarily rare. It includes signs and symptoms of both Wallenberg and Dejerine syndromes, however the Wallenberg syndrome is best on one facet.

  • Babinski-Nageotte and Cestan-Chenais syndrome. These are tremendously uncommon conditions that integrate some of the outcomes of 1-sided Wallenberg syndrome and Reinhold syndrome.

Maintaining the health of the medulla oblongata in the human body

  • The medulla oblongata is responsible for a variety of functions in the human body, most notably respiration and heart rate. The medulla oblongata is a critical part of the brainstem, and any damage to this area can have severe consequences. In order to maintain the health of the medulla oblongata, it is important to understand its anatomy and function.
  • The medulla oblongata is responsible for a variety of functions in the human body, most notably respiration and heart rate. Its importance to maintain health cannot be understated, as even minor disruptions to its function can lead to serious health problems. In this paper, we will discuss the importance of the medulla oblongata and the various ways in which it can be protected.
  • You can do numerous matters to assist prevent harm for your medulla or keep away from conditions that have an effect on it.

  • Eat a balanced weight loss program. Certain vitamin deficiencies, especially diet B12, can affect your brain, which include your medulla, and purpose foremost issues.

  • Stay physically active and preserve a wholesome weight. Circulatory and heart problems affect your mind, too. Stroke is an example of this, frequently taking place because of troubles on your coronary heart. Staying lively and retaining a wholesome weight can assist reduce your hazard.

  • Wear safety equipment as needed. Injuries in your head can affect your mind seriously, causing concussions or disturbing mind injuries. Wearing a safety device at some point of painting and playing sports can guard your brain from these varieties of accidents.

Maintaining a healthy nervous system

  • The nervous system is the master controlling and communicating system of the body. Every thought, feeling, and action is generated by the nervous system. Maintaining a healthy nervous system is essential for optimal health and functioning. This paper will explore the role of the nervous system in maintaining health and homeostasis.

  • Though vitamins and minerals are essential nutrients, they each play different roles in your body. One of the jobs of vitamin B-12 is to keep your nervous system functioning properly. A lack of B-12 can cause neurological problems, such as memory loss and problems with balancing and walking. Vitamin B-12 is found naturally in animal foods, such as meat, poultry, shellfish, eggs and milk.

Call your doctor properly away when you have any surprising adjustments in your fitness, such as losing coordination or noticing excessive muscle weak spots. You must also see your medical doctor when you have:


  • Vision troubles or headaches.

  • Slurred speech.

  • Numbness, tingling, or lack of sensation for your fingers or legs.

  • Tremors or tics (random muscle movements).

  • Changes in behavior or reminiscence.

  • Problems with coordination or transferring your muscle groups.
