The giant axon of the squid (Figure Q11–3) occu-pies a unique position in the history of our understandingof cell membrane potentials and nerve action. When anelectrode is stuck into an intact giant axon, the membranepotential registers –70 mV. When the axon, suspended in abath of seawater, is stimulated to conduct a nerve impulse,the membrane potential changes transiently from –70 mVto +40 mV.

Intro to Neuroscience Question Explain your reasoning and why you chose that answer.: Which of the following does NOT accurately describe medium spiny neurons (MSNs)? Group of answer choices They make a small number of synapses with many GPNs and a large number of synapses with a few GPNs They are GABAergic and therefore inhibitory. They are constitutively active to tonically inhibit the thalamus. They are activated by inputs from the cortex. All of the above are true

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?
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.
In the propagation of a nerve impulse: a. the refractory period begins as the K+ channel opens, allowing K+ ions to flow outward along their concentrationgradient. b. Na+ ions flow out of the axon with their concentration gradient. c. positive charges lower the membrane potential to its lowestaction potential. d. gated K+ channels open at the same time as the activationgate of Na+ channels closes. e. the depolarizing stimulus lowers the membrane potential toopen the Na+ gates.
