A placebo is basically an alternative medical treatment (e.g. pill) that doesn't <span>contain an active substance meant to affect health. So it isn't actually solving anything but it can have the placebo effect. Which can be assumed is the reason it is sometimes used in experiments. </span>

A placebo is kind of a "fake" treatment but, typically the person receiving a placebo is unaware it has no medical effect on them so they believe they are feeling better. For example, a lot of anxiety meds are placebos and people don't know so their brain tricks them into thinking they are feeling less anxious. This could be used in experiments where a group believes they are affected to see how they react

Sheath of schwann cell containing cytoplasm and nucleus that encloses myelin. True or False

chubhunter [2.5K]

The given question is not about true/false. The correct question is:

Question: Sheath of schwann cell containing cytoplasm and nucleus that encloses myelin.......

Answer:

Neurolemma

Explanation:

Schwann cells are one of the two types of neuroglia that produce myelin sheaths. Schwann cells produce the myelin sheath in the peripheral nervous system. These cells produce the myelin sheaths around axons during fetal development. During the process, several layers of the glial plasma membrane surround the axon. The Schwann cell’s cytoplasm and nucleus form the outermost layer. On the other hand, the inner part is composed of multiple layers of Schwann cell membrane and is called the myelin sheath. The outer nucleated cytoplasmic layer of the Schwann cell that encloses the myelin sheath is called the neurolemma.
