Problem 3

Membrane junctions that allow nutrients or ions to flow from cell to cell are (a) desmosomes, (b) gap junctions, (c) tight junctions, (d) all of these.

Step-by-Step Solution:
Step 1 of 3

1) Myelin sheaths are not one continuous covering – they are segmented with unmyelinated gaps known as the nodes of Ranvier. These myelinated fibers (axons) are able to send signals much faster than unmyelinated axons or the unmyelinated parts of a neuron (cell body, dendrites). The outer part of a Schwann cell (which is a type of glial cell listed below) is called the neurilemma. It helps in regeneration of damaged axons. Since Schwann cells are only located in the PNS, the brain and spinal cord are less able (or unable) to regenerate if damaged or destroyed.
