What is the function of the pontine?

What is the function of the pontine?

The pons, while involved in the regulation of functions carried out by the cranial nerves it houses, works together with the medulla oblongata to serve an especially critical role in generating the respiratory rhythm of breathing. Active functioning of the pons may also be fundamental to rapid eye movement (REM) sleep.

Where is the pontine region?

brainstem The pons is in the brainstem situated between the midbrain and the medulla oblongata, and in front of the cerebellum. A separating groove between the pons and the medulla is the inferior pontine sulcus. The superior pontine sulcus separates the pons from the midbrain.

What is pontine infarct?

When stroke happens in the pons, which is the upper section of the brain stem, it's called a pontine stroke. More formally, an ischemic stroke in the pons is also known as a pontine infarct or pontine cerebrovascular accident.

What type of stroke is a pontine 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).

What are the 3 functions of the pons?

The important functions performed by pons include;

• Respiratory control via Pnuemotaxic center and Apneustic center.
• Relay of fibers from cerebrum to cerebellum.
• Nuclei of four cranial nerves.
• Passage to corticonuclear and corticospinal tracts.

Why is pons called 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 live without a pons?

Because of the part that the Pons plays in hearing, eating, facial expression, and eye movement, the Pons is NOT something you could live without. It relays messages throughout the brain and controls too many important vital functions we as human beings need.

Who is thalamus?

The thalamus is a small structure within the brain located just above the brain stem between the cerebral cortex and the midbrain and has extensive nerve connections to both. The primary function of the thalamus is to relay motor and sensory signals to the cerebral cortex.

What causes pontine strokes?

Pons strokes can be caused by a blood clot or a ruptured blood vessel. Both types can lead to brain damage. People who have certain medical conditions, are inactive, or who smoke or use drugs are at higher risk for any kind of stroke. Your risk of stroke also increases with age.

What causes pontine hemorrhage?

Pontine hemorrhage is usually caused by uncontrolled systemic hypertension, resulting in a sudden loss of consciousness, quadriparesis, and pinpoint pupils.

What does pontine mean?

• “Pontine” refers to the stem of the brain, called the pons. “Myelinolysis” means that the myelin — a covering that protects the pontine nerve cells — is being destroyed. CPM usually happens as the result of another illness or medical condition. The destruction of myelin is generally not spontaneous.

What is a pontine lesion?

• A lateral pontine syndrome is a lesion which is similar to the lateral medullary syndrome, but because it occurs in the pons, it also involves the cranial nerve nuclei of the pons.

What is pontine haemorrhage?

• Pontine hemorrhage, a form of intracranial hemorrhage, is most commonly due to long standing poorly-controlled chronic hypertension. It carries a very poor prognosis. It carries a very poor prognosis.

What does myelinolysis, central pontine mean?

• Central pontine myelinolysis (CPM) is a rare neurological disorder that affects the brain . It's more common in adults than in children. "Pontine" refers to the pons, a part of the brain stem. "Myelinolysis" means that the myelin - the covering that protects nerve cells, including the pontine nerve cells - is being destroyed.
