Chapter 32, Problem 3CT
Hansen's disease, also known as leprosy, arises when bacteria infect the Schwann cells that wrap around axons of peripheral nerves to form a myelin .shealth. Attacks by the immune system on the bacteria-infected glial cells causes a loss of myelin in peripheral nerves. How is Hansen's disease similar to multiple sclerosis? Why do the symptoms differ? Why are people with Hansen's disease unusually prone to injuring themselves?

A patient has been experiencing numbness and pain in their hands and feet during the winter. They were initially diagnosed with Reynauds (which is caused by an overactive sympathetic nervous system cutting off blood flow to the hands in the cold), but recently they have been experiencing issues with fine motor control in their hands, and the doctor is concerned that it could be Multiple Sclerosis. How could you test to see which condition is causing this?
If it is MS, what is causing these symptoms? Why did it start in their hands and feet?
How would you treat this patient, if they have MS?
multiple sclerosis is a demyelinating disease in which the patient's immune system attacks and destroys the cells that form the myelin sheath in the central nervous system. what types of symptoms would you expect from such a disease? why? would Schwann cells or oligodendrocytes be affected? explain

- Which of the following is NOT TRUE concerning astrocytes? They are the most abundant glial cells They act as bridges between the blood vessels and neurons They form the myelin sheath around the axon They repair damage 1 points QUESTION 28 Damage to large numbers of oligodendrocytes in the CNS would result in loss of the structural framework of the brain. a breakdown of the blood-brain barrier. decreased production of cerebrospinal fluid. decreased insulation around axons. 1 points QUESTION 29 Which statement about lateral inhibition is false? It occurs via inhibitory neighbouring neurons. Neighboring input is inhibited from reaching the brain. It is characteristic only of receptors in the skin. It results in a sharpening of the sensation of contrast.arrow_forwardWhat two types of macromolecules are the main components of myelin? a. carbohydrates and lipids b. proteins and nucleic acids c. lipids and proteins d. carbohydrates and nucleic acidsarrow_forwardMultiple sclerosis is a disease in which the immune system attacks and destroys the myelin sheath surrounding nerve cells.

- Neurofibromatosis type 1 is a condition where tumours can grow in the nerves near the skin. The growth of tumours prevents the action potentials from quickly travelling through the neurons. Identify the nerve structure from the image below and the division of the nervous system affected by neurofibromatosis type 1. CNS = Central Nervous System PNS = Peripheral Nervous System Select one: a. Nerve Structure Division of Nervous System 3 PNS b. Nerve Structure Division of Nervous System 4 CNS c.

Much of what we know about the difference between the left and right hemispheres came from the study of patients with a severe form of epilepsy. To help control the number, duration, and intensity of the epileptic seizures, The corpus callosum was cut. By studying these individuals, Roger Sperry and others learned that the two hemispheres are specialized for different types of task and different modes of thought. Which hemisphere and most people would be better at putting together a puzzle? A. Neither- this is better controlled by the cerebellum B. Both are equally good at this task C. Left D. Rightarrow_forward

What would be a possible treatment for this disease? (So basically- what would be a possible way to increase the amount of ACH in the synaptic cleft?)arrow_forwardThe concept of “labeled lines” states that each nerve input to the brain reports only a particular type of information, such as auditory versus visual information. Does this happen because the nature of the nerve fibers conveying the information is unique or because the nature of the brain location where the signals are received is unique? How do you know this?arrow_forward
