Question
Chapter 37, Problem 12TYU
Summary Introduction
To describe:
How the electrical properties and structure of vertebrate neurons reflect the differences and similarities with other animal cells.
Concept introduction:
Neuron is an excitable cell (electrically), which receives, transmits and processes the information with the help of chemical and electrical signals. The signals between the neurons occur with the help of synapses.

The image attached below depicts a histological slice of human cerebral cortex tissue.Using knowledge of the central nervous system and various cell-cell interactions, identify thekey type(s) of cell junctions present in this image (for example, tight junctions, gap junctions, and adherens junctions/desmosomes). Briefly describe the function of these celljunctions. How would the function of the central nervous system be impaired if your above identified celljunctions were disrupted?

The axon contains microtubules and neurofilaments, bounded by a plasma membrane known as the axolemma. Outside the plasma membrane of the axon is the myelin sheath, which is composed of the tightly wrapped plasma membrane of a Schwann cell.

- Watch this video (http://openstaxcollege.org/l/summation) to learn about summation. The process of converting electrical signals to chemical signals and back requires subtle changes that can result in transient increases or decreases in membrane voltage. To cause a lasting change in the target cell, multiple signals are usually added together, or summated. Does spatial summation have to happen all at once, or can the separate signals arrive on the postsynaptic neuron at slightly different times?
