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.

What is the pons of the brain?

The pons is the largest part of the brainstem, located above the medulla and below the midbrain. It is a group of nerves that function as a connection between the cerebrum and cerebellum (pons is Latin for bridge).

What does pontine nucleus do?

The pontine nuclei (PN) are the largest of the precerebellar nuclei, neuronal assemblies in the hindbrain providing principal input to the cerebellum. The PN are predominantly innervated by the cerebral cortex and project as mossy fibers to the cerebellar hemispheres.

What does the pons measure?

The pons powers the functions of the head and face The brainstem is made up of three sections, and carries vital information to the body. The pons relays information about motor function, sensation, eye movement, hearing, taste, and more.

What happens if pons are damaged?

Pons also relays sensory information and signals governing sleep patterns. If pons is damaged, it may cause loss of all muscle function except for eye movement.

How does the pons affect behavior?

The pons helps to regulate the respiratory system by assisting the medulla oblongata in controlling breathing rate. The pons is also involved in the control of sleep cycles and the regulation of deep sleep. The pons activates inhibitory centers in the medulla in order to inhibit movement during sleep.

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.

What are the pontine fibers?

The fibres that give the pons its name are efferent fibres running across the midline from the pontine nuclei to the central part of the cerebellar cortex. Fibres from the cerebral cortex travel to the pontine nuclei in the corticopontine tracts, passing through the internal capsule on their way to the pons.

What is an oblongata?

The medulla oblongata or simply medulla is a long stem-like structure which makes up the lower part of the brainstem. It is anterior and partially inferior to the cerebellum. It is a cone-shaped neuronal mass responsible for autonomic (involuntary) functions, ranging from vomiting to sneezing.

What is the function of pons varolii?

The main function of the varoli’s bridge is to maintain the balance and position of the head and body. Besides, Varoli’s Bridge contains parts like neural pathways and tracts. The neural pathway conveys signals from the brain to the medulla and cerebellum, while the tracts transport the sensory waves to the thalamus.

How does the pons work?

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.

Can you recover from pons damage?

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 does pontine mean?

Definition of pontine : of or relating to the pons : of or relating to the pons a study of pontine lesions

Are Pons and pontine the same?

pontine | pons | Related terms |. is that pontine is (anatomy) of or pertaining to the pons in the brain stem while pons is (anatomy) a band of nerve fibres, the pons varolii, within the brain stem.

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. 1 Symptoms. 2 Causes.

What does myelinolysis, central pontine mean?

Central pontine myelinolysis ( CPM) is a neurological condition involving severe damage to the myelin sheath of nerve cells in the pons (an area of the brainstem ).
