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.

- 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? Explain your answer.arrow_forwardView the University of Michigan Webscope (http://openstaxcollege.org/l/nervefiber) to see an electron micrograph of a cross-section of a myelinated nerve fiber. 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.

Which of the following is correct classification of these neurons: a. all three are presynaptic b. first is presynaptic, other two are postsynaptic c. first and second are presynaptic, third is postsynaptic d. first and second are presynaptic, second and third are postsynaptic e. all three are postsynapticarrow_forwardQuick question on the process of movement Multiple sclerosis is a disease in which the peripheral neurons lose their myelin sheath. In this disease, voluntary movement of the limbs is slowed because; Pick the ones that are true the rate of opening of ligand-gated Na+ channels is decreased. the generation of the action potential is blocked at points along the unmyelinated region due to the absence of voltage-gated channels the action potential amplitude is degraded at the Nodes of Ranvier of the peripheral neuron. The Schwann cells are targeted and destroyed by the immune system, affecting saltatory propagation. the rate of opening of ligand-gated Na+ channels is decreased.arrow_forward
