Neurophysiology

Retrobulbar neuritis is inflammation of the optic nerve behind the eyeball, leading to vision loss, usually in one eye. It is typically associated with multiple sclerosis or other demyelinating conditions. Treatment may involve corticosteroids to reduce inflammation and improve vision.

Hello My name is Tanya King. I watch motel on his shows about ms. I have been trying to email him there is no web site. my ms is attacking my eyes. that is there to do I cant take prednoze so the Dr said there isn't nothing they can do. i WAS JUST WONDERING if he had any thoughts to help me. i am a strong person Tanya King 765-759-1154 god bless

Yes, optic neuritis can go into remission. In some cases, the inflammation causing optic neuritis resolves on its own, leading to improvement in vision. However, it is important to monitor for any recurrence or worsening of symptoms.

The axon needs proteins that are generated in the soma, to aid the synaptic knob or even serve as ion channels, and the proteins travel distally to get there. Other substances need to be disposed of or recycled, and they travel back to the soma, proximally. Therefore materials travel down and up the axon which makes it bidirectional.

Stroke can cause difficulty swallowing, leading to food or liquid entering the airway instead of the esophagus. This increases the risk of aspiration pneumonia, as the lungs can get infected with bacteria from the swallowed material. It is important to assess swallowing function after a stroke to prevent complications like aspiration pneumonia.

Venous thrombosis prevention involves measures such as staying active, avoiding prolonged periods of immobility, wearing compression stockings, and taking anticoagulant medications if necessary. It is important to manage risk factors such as obesity, smoking, and certain medical conditions to reduce the likelihood of developing venous thrombosis.

Activating yeast involves hydrating it in warm liquid to awaken it from its dormant state, activate its enzymes, and kickstart the fermentation process. This helps the yeast to multiply and produce carbon dioxide, which leavens the dough and gives it a rise.

The amygdala is the part of the brain that is thought to regulate the emotional response to odors. It plays a key role in processing and associating emotional responses with olfactory stimuli.

Late stage kuru symptoms can include difficulty swallowing, severe tremors, difficulty walking, and emotional instability. These symptoms are indicative of advanced neurological damage caused by the kuru prion disease.

Jealousy is thought to involve the release of various neurotransmitters in the brain, such as dopamine, norepinephrine, and serotonin. These chemicals are associated with arousal, motivation, and the processing of emotions.

As the action potential passes an area on the axon, sodium channels are closed, preventing influx of more sodium ions. At the same time, voltage-sensitive potassium channels open, allowing the membrane potential to fall quickly. After this repolarization phase, membrane permeability to potassium remains high, allowing for the "afterhyperpolarization" phase.

During this entire period, while the sodium ion channels are forced closed, another action potential cannot be generated except by a much larger input signal.

This helps to prevent the action potential from moving backwards along the axon.

The resting membrane potential is determined by the concentration gradient of ions across the cell membrane, specifically sodium (Na+), potassium (K+), and chloride (Cl-). The uneven distribution of these ions maintained by ion pumps and channels sets up an electrical charge across the membrane, leading to a negative resting potential. The sodium-potassium pump plays a key role in establishing and maintaining this potential.

That is called cognitive impairment or cognitive difficulties. It refers to problems with learning, memory, attention, and other mental functions that affect the ability to acquire new knowledge.

Nothing stays the same, right? The answer is, of course.

When a neurotransmitter lands on their receptor site, they can either excite of inhibit the receiving cell. To excite a cell, positive sodium ions flow to it, which depolarizes the membrane in a similar way to a nerve impulse. The depolarizing effect spreads through the membrane and only last for 1/3 of a millisecond.

Yes, this may be a cause of permanent and severe brain damage. Hypoperfusion means there is an insufficient amount of blood flowing to those parts of the brain. The frontal lobe has neurons that function to regulate emotion and integrate multiple sources of information. The temporal lobes are involved in speech, movement, language and artistic expression.

Nursing management of neuritis involves providing supportive care to alleviate symptoms such as pain and discomfort, educating patients on proper medication usage and self-care techniques, and monitoring for complications or changes in condition. Nurses play a vital role in coordinating care, advocating for patients, and working collaboratively with healthcare team members to ensure optimal outcomes for patients with neuritis.

The double membrane of the nucleus enclosing DNA and any other genetic material in a eukaryotic cell is called the nuclear membrane. It separates the DNA from the cytosol. The space between the two membranes is called the perinuclear space and is from 20 to 100 nm wide. The rough endoplasmic reticulum connects with the outer membrane. You can easily see these structures in a raw chicken egg. The nuclear membrane is often referred to as the nuclear envelope.

Nobody knows exactly how these drugs help, but the current theories indicate that they act by increasing or decreasing availability of specific neurotransmitters inside the synaptic gap between nerve cells.

This is a response, specifically a reflexive response known as salivation. The sight or smell of food triggers the brain to send signals to the salivary glands, causing the mouth to water in preparation for eating.

The main symptom of auditory neuritis is sudden hearing loss in one ear, which may be accompanied by ringing in the ear (tinnitus), dizziness, or problems with balance. It can be caused by inflammation of the auditory nerve or damage to the cochlea.

Your body gets to hot. If you don't drink ALOT of water, your body runs out of water VERY fast, if you don't drink water.

Answer:

During extreme heat the human brain that co-ordinates body temperature gets signals from the body to cool & supplies fluids through blood supply that drains out from the brain to dehydrating organ cells & tissues in the extreme heat.This is the reason for fainting. If the brain is kept at cooler temperature than the body then a person does not faint.
