Concept explainers

Communication

Communication is a method of transferring information between two persons or organisms. Communication is possible using mutually understood behaviors such as signs, symbols, or language. In the year 1980, S. F. Scudder proposed communication theory. According to his ideas, all living beings on the earth communicate, but the methods of communication differ. Communication skills are now part of soft skills.

View 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. What aspects of the cells in this image react with the stain that makes them the deep, dark, black color, such as the multiple layers that are the myelin sheath?

Drugs which open Cl- channels in synapses :-a- cause depolarization of postsynaptic membraneb- cause hyperpolarization of postsynaptic membranec- enhance release of neurotransmitters from synaptic knobsd- enhance response of postsynaptic neurons

Ordinarily, a neuron’s trigger zone is activated before any other part ofan axon, so a wave of action potentials occurs as sodium channelsopen in the direction of the synaptic terminal. What would happen ifyou artificially stimulated an axon to reach threshold potential midwayalong its length rather than at the trigger zone?a. Action potentials would occur in the direction of the synapticterminal.b. No action potentials would occur.c. Action potentials would occur in the direction of the trigger zone.d. Both a and c are correct.
Which of the following is the most direct result of depolarizingthe presynaptic membrane of an axon terminal?(A) Voltage-gated calcium channels in the membrane open.(B) Synaptic vesicles fuse with the membrane.(C) Ligand-gated channels open, allowing neurotransmittersto enter the synaptic cleft.(D) An EPSP or IPSP is generated in the postsynaptic cell.
Would anyone be able to explain these different channels? I would like an explanation as to why voltage gated membranes are associated with axon membranes (although it's prob because of membrane potential differences and depolarization/hyperpolarization?), why ligand gated channels are primarily at synapses (via neurotransmitters?), etc.
A change in the voltage across a neuron’s plasma membranethat makes the neuron less likely to fire an action potential isa. a change that makes the resting potential less negative.b. an excitatory postsynaptic potential.c. an inhibitory postsynaptic potential.d. a change that lowers the threshold.
