    Formed by Schwann cells in the PNS?

    • Nodes of Ranvier

    • Unmyelinated Axons

    • Dendrites

    • Myelin Sheath

    Correct Answer
    A. Myelin Sheath
    Explanation
    The myelin sheath is formed by Schwann cells in the peripheral nervous system (PNS). It is a protective covering that surrounds and insulates the axons of neurons, allowing for faster and more efficient transmission of electrical signals. The myelin sheath is essential for the proper functioning of the nervous system, as it helps to prevent signal loss and interference. The nodes of Ranvier, on the other hand, are small gaps in the myelin sheath where the axon is exposed. Unmyelinated axons do not have a myelin sheath at all. Dendrites, on the other hand, are the branch-like extensions of neurons that receive signals from other neurons.

    What are synapses?

    • Short processes which bring signals into the cell body

    • Long processes that send signals out of the cell body

    • Gaps between axons and post synaptic cells

    Correct Answer
    A. Gaps between axons and post synaptic cells
    Explanation
    Synapses are the gaps between axons and post synaptic cells. They are the junctions where signals are transmitted from one neuron to another. Axons are long processes that send signals out of the cell body, while synapses are the specific locations where these signals are transmitted across the gap to the post synaptic cell. Therefore, the correct answer is "gaps between axons and post synaptic cells".
