Question: What Would Happen If The Pons Was Damaged?

Why is the Pons important?

Pons is an essential part of the brain located above the medulla.

It falls in the category of the hindbrain.

Pons is very important part of brain for the regulation and control of a number of vital functions.

It not only acts as a control center, but also contains nuclei of some important cranial nerves..

What happens if hindbrain is damaged?

Most of the cranial nerves have both sensory and motor components. Damage to the medulla is often fatal. Drugs such as the opiates and cocaine have profound effects on the medulla nuclei when taken at high doses; which is why these substances may result in “overdose” and death.

What side of the brain controls sleep?

Neurons in a part of the hypothalamus called the ventrolateral preoptic nucleus (VLPO) connect directly to the many arousal-promoting centers. Rather than stimulating activity in these areas, signals from VLPO neurons inhibit their activity. By shutting down the arousal centers, the VLPO promotes sleep.

What would happen if the medulla was damaged?

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. If your medulla oblongata becomes damaged, it can lead to respiratory failure, paralysis, or loss of sensation.

What is the function of the pons in the brain?

The pons (part of metencephalon) lies between the medulla oblongata and the midbrain. It contains tracts that carry signals from the cerebrum to the medulla and to the cerebellum. It also has tracts that carry sensory signals to the thalamus.

How does the Pons affect sleep?

The brain stem (especially the pons and medulla) also plays a special role in REM sleep; it sends signals to relax muscles essential for body posture and limb movements, so that we don’t act out our dreams.

What happens if your amygdala is damaged?

People tend to choose avoiding losses over acquiring gains—a behavior known as loss-aversion. But people with damage to the amygdala—an almond-shaped part of the brain involved in emotion and decision-making—are more likely to take bigger risks with smaller potential gains, De Martino’s study found.

What behaviors would be affected if there was damage to the brain stem?

A brain stem injury can cause dizziness or lack of motor function, with more severe cases resulting in paralysis, coma, or death.

What is the Pons made of?

The Pons and Cerebellum The pons is comprised of a basilar portion and an internal region, the pontine tegmentum. The basilar pons contains pontine nuclei, important fiber bundles (particularly the corticospinal fibers and corticopontine-pontocerebellar system) that are integral to motor function.

What does damage to the pons cause?

Harvey explained it in this way: “If injury in one side of the pons causes weakness on the opposite side of the body and facial and eye movement weakness on the same side of the body, then when stroke hits both sides of the pons, you’re going to get weakness on both sides of the body, paralysis on both sides of the …

What happens if there is damage to the midbrain?

Damage to the midbrain can result in a wide variety of movement disorders, difficulty with vision and hearing, and trouble with memory. Because the midbrain houses the hypothalamus, it also plays a major role in automatic body functions.

What does the pons control?

The pons contains nuclei that relay signals from the forebrain to the cerebellum, along with nuclei that deal primarily with sleep, respiration, swallowing, bladder control, hearing, equilibrium, taste, eye movement, facial expressions, facial sensation, and posture.

What happens if the brainstem is damaged?

Even if a brain stem injury does not cause breathing problems, it can cause a litany of other problems and symptoms. For example, the brain stem can become compressed because of swelling, which can lead to hemorrhaging and an eventual stroke.

Can the brain stem repair itself?

“The brain is not good at repairing itself, but these newly-discovered stem cells suggest there may be a way to improve its ability,” says one of the researchers, molecular biologist Andrea Brand. “These stem cells are in a dormant state, but once awake, they have the ability to generate key brain cells.”

What does the Pons look like?

The pons is a broad horseshoe-shaped mass of transverse nerve fibres that connect the medulla with the cerebellum. It is also the point of origin or termination for four of the cranial nerves that transfer sensory information and motor impulses to and from the facial region and the brain.

Why is the Pons called a bridge?

Pons is Latin for “bridge”; the structure was given its name by the Italian anatomist Costanzo Varolio, who thought that the most conspicuous portion of the pons resembled a bridge that connected the two cerebellar hemispheres.

Can you recover from a pons stroke?

Recovery from a pontine stroke is possible. If you have experienced a pontine stroke, once your symptoms stabilize over time, the focus of your recovery will be based on preventing complications such as choking and preventing further strokes from happening.

What is a pons stroke?

A pontine cerebrovascular accident (also known as a pontine CVA or pontine stroke) is a type of ischemic stroke that affects the pons region of the brain stem. A pontine stroke can be particularly devastating and may lead to paralysis and the rare condition known as Locked-in Syndrome (LiS).
