Schwann cells are replaced by oligodendrocytes
Myelin bundles around axons produced by Schwann cells are damaged
Astrocytes are the target in this process
abrupt transmission will not occur in areas that appear white
A.Sodium / Potassium pumps no longer function in the CNS
B.Schwann cells are replaced by oligodendrocytes
C.Myelin bundles around axons produced by Schwann cells are damaged
D.Astrocytes are the target in this process
E.abrupt transmission will not occur in areas that appear white
Explanation / Answer
MRI (magnetic resonance imaging) is a noninvasive diagnostic test that takes detailed images of the soft tissues of the body. Unlike X-rays or CT, images are created by using a magnetic field, radio waves, and a computer.Similar to CT, MRI allows your doctor to see your body in narrow slices, each about one quarter of an inch thick. For example, imagine that you are slicing a loaf of bread and taking a picture of each slice. It can view slices from the bottom (axial), front (coronal), or sides (sagittal), depending on what your doctor needs to see
b is the answer Schwann cells are replaced by oligodendrocytes
