When a neuron fires an action potential, the information travels through the axon,the dendrites, and the cell body, but not in that order. Place these three structures in the correct order.
a channel can be gated mechanically, voltage
or by a ligand. When you hear a sound all three of these type channels are being
utilized. Explain generally where/how each of these channels are being utilized
starting from hearing the sound, through travelling down a nerve to transmission
to another nerve.
A pin can be pressed against the skin lightly and elicit no response from the pain receptor. However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly be withdrawn through a reflex arc.
Use what you know about threshold potential and the all-or-none principle to explain different levels of sensation (light touch or pain)

- Because the long axons of neurons look like electrical wires, and both neurons and electrical wires conduct electricity, it is tempting to equate the two. Compare and contrast the functioning of axons and electrical wires in terms of their structure and the nature of the electrical signals they conduct. Please include references.arrow_forwardFill in the blank: The moment following the passage of an action potential during which a threshold stimulus will not triggeranother impulse is called the ___________________ period.arrow_forwardA voltmeter is used to measure the potential difference across a neuron’s membrane. A change in potential difference will occur when an action potential is generated. A neurologist uses a giant squid neuron to study the propagation of an action potential. She places two voltmeters on the axon membrane to measure the potential difference: one near the dendrite and the other at the axon terminal. A stimulus is then applied. Often, the stimulus is applied at one end of the neuron. In this experiment, the scientist decides to stimulate the middle of the neuron. Which statement describes what the scientist would observe at the voltmeters? Select one: a. Both voltmeters will indicate changes to the potential difference. b. No changes to the potential differences will be registered at the voltmeters. c. The voltmeter at the dendrite will indicate a change to the potential difference. d.

Multiple sclerosis is a disease in which demyelination occurs in neurones involved in coordinating muscle movement. Using your knowledge of nerve impulse generation and propagation, explain how nerve impulse generation and propagation would be affected in people who have multiple sclerosis. The explanation needs to be in the form of a step by step sequence of annotated drawings. This could be in the form of an annotated cartoon/picture strip. Compare this to nerve impulse generation and propagation in an individual who does not have multiple sclerosis.arrow_forwardReceptors such as those in the inner ear, respond to stimulation with an AM response. In contrast, a neuron connected to that receptor, sending information centrally (ex: the brain) respond in an FM manner.

(1) ______________________ are a group of endogenous chemicals responsible for signaling between neurons and other cells (there is very little direct “electrical” connection between neurons). Thus, signaling of the nervous system is a bioelectrochemical process affected by neurotransmitters. Neurotransmitters act on proteins called (2) _______________, which are found on cell membranes in synapses. (3) _______________ are very narrow gaps (20–50 nm) between neurons allowing for chemical transmission via neurotransmitters. The binding of neurotransmitters to pre- and post-synaptic receptors results in changes in the polarization of the cell. Neurotransmitter actions that increase the likelihood of initiating an action potential are called (4) __________________ (EPSPs) while those that reduce the likelihood of an action potential are termed (5)…arrow_forwardWhich of the following stimuli (s) produces only a local potential and no action potential?
