Question

QUESTION 1 Atter examining a patient with a neurological disorder that interferes with walking, a neurologist determines that a Mycoplasma bacterium is causing the destruction of the myelin sheath around the axons in the patient's peripheral nerves. What specific cell type is affected in this patient? O A Schwann cells B Microga C Astrocytes QUESTION 2 Neurotransmitters have different effects in different cells. True False QUESTION 3 Fallure of the blood-brain barrier have been implicated in seizures. Which cells might be involved in the failure of the biood-brain barrier? -A Mcrogia B Schwann ceils O Astrocytes DOilgodendrocytes

Explanation / Answer

Please find the answers below:

Answer 1: Choice A (Schwann cells are myelinated neurons which are directly affected in this type of infection, thus causing disease in the individual)

Answer 2: True (Depending upon the nature of neurotransmitter and the nature of receptor found on cell it attaches, the cytoplasmic molecular signalling can be different since the carboxyl domain of each receptor on the cytoplasmic side is different in nature)

Answer 3: Choice C (Astrocytes are the specialized type of neurons which help in maintaining the function and organization of blood-brain barrier. Loss in function of these cells can be deleterious for the blood-brain barrier)

Answer 4: Choice D (The flow of information takes place from a synapse, followed by its reception at the axon's proximal dendrites and then hillock. The information is passed through the cell body and finally transmitted out via the terminal dendrites into synapse again)
