What does Guillain-Barre syndrome do?
The disease affects the myelin sheath, which coats nerve cells. It causes progressive muscle weakness and paralysis
A deterioration in the myelin sheaths of motor axons to the lower leg would be expected to?
Cause leg pain and weakness
What insulates nerve fibers?
Myelin sheaths insulate nerve fibers
What is the fatty tissue that covers axons and speeds up impulses as they travel from cell to cell?
That substance is called the myelin cell or myelin sheath.
The layer of lipid around an axon is called?
Myelin sheath
What does infectious polyneuritis do?
The disease affects the myelin sheath, which coats nerve cells. It causes progressive muscle weakness and paralysis
What does Guillain-Barre syndrome do?
The disease affects the myelin sheath, which coats nerve cells. It causes progressive muscle weakness and paralysis
What destroys the myelin sheath?
There are few diseases that destroy the myelin sheath like sub acute combined degeneration of myelin sheath. There is also ascending myelitis, which is a serious complication of rabies vaccine. The incidence is one in ten to thirty thousand.
What is demylation?
Probably you mean deyelination, which is a loss of the myelin sheath covering many nerves. Myelin helps nerve transmission go faster, and there are several demyelinating diseases, including multiple sclerosis, that destroy myelin. this interferes with nerve transmission and leads to distressing loss of muscle control and sensory input.
A deterioration in the myelin sheaths of motor axons to the lower leg would be expected to?
Cause leg pain and weakness
How does multiple sclerosis affect human health?
To create movement and simple bodly functions the neurons in our bodies need to relay messages to one another by electrical impulses. When someone has ms the body begins to destroy what is called myelin sheaths and the cells that produce myelin. The sheaths are then replaced by hard tissue which don't allow the electrical impulses to pass throu. Which can cause mild to sever muscle weakness abnormal sensations such as numbness or tingling over any part of the body, vision change, loss of coordination, tremors, paralysis, poor posture and bowel and bladder dysfunction. All depending on how sever the case is.
What can cause locked-in syndrome?
Locked-in syndrome can occur after severe, catastrophic brain injuries due to massive stroke , traumatic head injury, or ruptured aneurysm. Diseases that destroy the myelin sheath around nerves and the toxic effects of medication overdose
What insulates nerve fibers?
Myelin sheaths insulate nerve fibers
What causes MS?
Axons are located within the neurons and are extremely tiny. They receive information from a neighboring dendrite (also part of a neuron). The axon is surrounded by what is called a myelin sheath--which acts as a sealer for the axon. When the information in the form of electrical signals passes down the axon, the myelin sheath will inhibit the ions from escaping. However, in multiple sclerosis, the myelin on the action is degenerated and cannot perform its incubating function. This causes extreme slowing of the electrical signal, which in turn affects muscles weakness and poor coordination. Summed up: The myelin sheath is damaged and allows ions to escape the axon. This leads to weakness in muscle and lack of coordination.
A pathological condition in which there is progressive destruction of the myelin sheath?
Demyelinating diseases such as Multiple Sclerosis, Krabbe's Disease, and Guillain-Barre Syndrome involve degeneration of the myelin sheath. In these conditions, movement is limited to minimal as nerve conduction is reduced due to the loss of efficacy of the myelin.
Adrenoleukodystrophy has what type of symptoms?
Adrenoleukodystrophy (ALD) affects the myelin of the central nervous system. Symptoms can vary a great deal making diagnosis difficult but include weakness of muscle tone, aphasia, strabismus, hearing loss and worsening muscle weakness and leg stiffness.
What is the nervous tissue involved in multiple scoliosis?
Along the axon of a neuron there is an insulating fatty substance called the myelin sheath. With MS the myelin breaks down so the neuron/nerve loses its capability of conducting impulses. Therefore 'messages' sent via the motor nerves eventually do not reach muscles and the patient has problems controlling movement which can lead to paralysis.
