Besides the medulla oblongata, your brainstem also has a structure called the pons. The pons is a major structure in the upper part of your brainstem. It is involved in the control of breathing, communication between different parts of the brain, and sensations such as hearing, taste, and balance.
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.
Furthermore, what would happen if there was damage to the pons? Damage to the pons can result in: Facial sensation loss. Corneal reflex loss. Facial muscle drooping.
In this manner, where is the pons area of the brain?
The pons is a portion of the brain stem, located above the medulla oblongata and below the midbrain. Although it is small, at approximately 2.5 centimeters long, it serves several important functions.
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.
What does the pons regulate?
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.
What does the pons do psychology?
Pons: n. a structure on the brain stem that lies above the medulla and regulates sleep, arousal, consciousness, and sensory processes. Pons is Latin for bridge. It consists of nerve fibers that connect the cerebrum and the cerebellum, and bridges sensory information between the left and right hemispheres of the brain.
What causes a pons stroke?
Causes. An ischemic stroke occurs when a blood clot forms, blocking the blood flow through an artery to a certain region in the brain. In rare instances, a stroke involving the pons, typically called a pontine stroke, maybe the result of an injury to an artery caused by sudden head or neck trauma.
How does the pons regulate sleep?
Projections from the locus coeruleus to a nearby region (sometimes called the subcoruleus region) of the pons also help to regulate rapid eye movement (REM) sleep. Due to its central location between the brain and spinal cord, the pons also serves as a conduit for many tracts passing up and down the brainstem.
How does Pons control breathing?
The pons is the other respiratory center and is located underneath the medulla. Its main function is to control the rate or speed of involuntary respiration. The pnuemotaxic center sends signals to inhibit inspiration that allows it to finely control the respiratory rate.
Which center is located in the pons?
The respiratory center is located in the medulla oblongata and pons, in the brainstem. The respiratory center is made up of three major respiratory groups of neurons, two in the medulla and one in the pons.
What is the function of Pons 10?
The pons can be define as the part of the hindbrain. The pons serves as a communication medium between the two hemispheres of the brain. It deals with important functions of the body named as eye movement, respiration, sleep, swallowing, hearing and bladder control.
What cranial nerves are in the pons?
There is one cranial nerve associated with the pons proper, the trigeminal nerve (cranial nerve V). Three other cranial nerves are located at the pontomedullary junction: the abducens nerve (cranial nerve VI), the facial nerve(cranial nerve VII), and the vestibulocochlear nerve (cranial nerve VIII).
Can you recover from a pons stroke?
Rehabilitation for Pontine Stroke Some side effects of pontine stroke can be restored through rehabilitation. Specifically, loss of sensation, weakness in the limbs, and difficulty with speech and swallowing can be improved.
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).
What type of arousal is Pons associated with?
The pons also serves to connect the cerebral cortex to the medulla oblongata via the cerebral peduncles. The pons is involved in many autonomic and sensory functions including arousal, respiratory processes, fine motor control, equilibrium, muscle tone, and the Circadian cycle (specifically regulating sleep).
What is the cerebellum responsible for?
The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity.
Which side of the brain is worse to have a stroke?
Effects of left-sided stroke. Some problems that happen after stroke are more common with stroke on one side of the brain than the other. In most people, the left side of the brain controls the ability to speak and understand language.
What happens when the cerebellum is damaged?
Damage to the cerebellum can lead to: 1) loss of coordination of motor movement (asynergia), 2) the inability to judge distance and when to stop (dysmetria), 3) the inability to perform rapid alternating movements (adiadochokinesia), 4) movement tremors (intention tremor), 5) staggering, wide based walking (ataxic gait
