Question
Chapter 13.5, Problem 17CYU
Summary Introduction
To review:
The ions that cause depolarization in the hair cells and the reason behind the movement of potassium ions into such cells, instead of moving out.
Introduction:
Hearing is the process that is done by the ears. Hearing takes place when the auditory ear of the temporal lobe cortex is regulated. But, prior to this, the sound waves need to be propagated via the air, fluids, bones, and membranes to regulate the receptor cells present in the spiral organ.

The graphs represent a membrane potential recording from a hair cell (graph A) and a neuron it synapses with (graph B) in response to a small stimulus at the time indicated by an arrow.
Explain how each graph would change in response to a stimulus of much greater intensity and why
Which of the following is true regarding the difference between graded and action potentials?
a.) Action potential occur only when the surface of the neuron is myelinated, but graded potentials occur in both in both myelinated and non-myelinated neurons.
b.) The magnitude of action potential depends on the magnitude of the stimulus, whereas graded potentials are all or none.
c.) The magnitude of graded potential depends on the magnitude of the stimulus, whereas action potentials are all or none.
View an electron micrograph of a cross-section of a myelinated nerve fiber image below. 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?

- The concentration of potassium ions inside a nerve cell membrane is higher than the concentration of sodium ions outside the mem-brane, yet the inside of the membrane (where the cation concentra-tion is higher) is negative to the outside. Explain this observation in terms of permeability properties of the membrane.arrow_forwardIf extracellular [Na1] is elevated, how would the resting potential and action potential of a neuron change?arrow_forwardAssume a neuron is at rest and the following changes happen: Step 1: Neurotransmitter binds to an ionotropic excitatory neurotransmitter receptor causing an EPSP. Step 2: With the neurotransmitter still bound either a NAM or non-competitive antagonist bind to the allosteric site of the receptor. Answer the following questions that explains how the NAM and non-competitive antagonist would differ in their actions. 4.) A. Going from step 1 to step 2 what would happen to the ionotropic receptor (ion channel) as a result of the NAM. B. Going from step 1 to step 2 what would happen to the ionotropic receptor (ion channel) as a result of the non-competitive antagonist. C. Going from step 1 to step 2 how would membrane potential change as a result of the NAM D. Going from step 1 to step 2 how would the membrane potential change as a result of the non-competitive antagonist.arrow_forward

- In most neurons, membrane depolarization leads to the opening of voltage-dependent ion channels, generation of an action potential, and, ultimately, an influx of Ca2+, which causes release of neurotransmitter at the axon terminus. Devise a cellular strategy by which hyperpolarization in rod cells could produce excitation of the visual pathway and passage of visual signals to the brain. (Hint: The neuronal signaling pathway in higher organisms consists of a series of neurons that relay information to the brain. The signal released by one neuron can be either excitatory or inhibitory to the following, postsynaptic neuron.)arrow_forwardb) You are having a shower with warm water, and all of a sudden, the water turns ice cold! How do you think your temperature sensory neurons code this very noticeable and strong stimulus? a) They produce larger EPSPS at the same rate as under the warm water condition. b) They produce larger, but the same number of, action potentials as under the warm water condition. c) They produce smaller EPSPS at a higher rate than under the warm water condition. d) They produce the same number and size action potentials that travel faster down the neurons than under the warm water condition. e) They produce more action potentials of the same size as under the warm water conditionarrow_forwardIndicate where all the structures are locatedarrow_forward
