If an Inhibitory Interneuron is stimulated & generates an Action Potential, it will:
A. first hyperpolarize, and then release a neurotransmitter
B. release a neurotransmitter that hyperpolarizes the postsynpatic cells
C. release an enzyme that hydrolyzes an excitatory neurotransmitter
D. release a neurotransmitter that depolarizes the postsynpatic cells
E. Inhibitory Interneurons can not depolarize and conduct action potentials
Correct answer:- (A) first hyperpolarization and then release a
neurotransmitter
Explanation:- if a inhibitory interneuton is stimulated through a
inhibitory e postsynaptic potential then inhibitory postsynaptic
potential is generated and postsynaptic membrane potential becomes
more negative than the resting membrane potential, and this is
called HYPERPOLARIZATION.
If an Inhibitory Interneuron is stimulated & generates an Action Potential, it will: A. first hyperpolarize,...
11. Acetylcholine is both an excitatory and inhibitory ligand depending on the location of its receptor. What does Acetylcholine do that makes it "excitatory"? a. It causes a cell membrane to depolarize and produce Excitatory Post Synaptic Potentials b. It opens K+ ion channels when it binds to its receptors c. It causes a cell membrane to hyperpolarize 12. The bonding of Acetylcholine to its muscarinic receptors on smooth muscle causes gated K+ channels to close. This action is described...
need help In this 4 question please and thank you
Question 10 (2 points) (True/false) During the rising phase of the action potential, the charge inside of the axon changes from negative to positive (depolarizes) True False Question 11 (2 points) (True/false) During the rising phase of the action potential, potassium channels (gates) open and allow the cell to depolarize. True False An interneuron OA) Receives excitatory or inhibitory inputs from other neurons and then can activate or not activate...

Graded potentials may: W. initiate an action potential. X. depolarize the membrane to the threshold voltage. Y. hyperpolarize the membrane. Z. be called EPSPs or IPSPs. Select one: a. if only W, X and Y are correct b. if only W and Y are correct c. if only X and Z are correct d. if only Z is correct e. if all are correct Feedback The correct answer is: if all are correct explanations all options plz abcde short answer
Cell # 1 forms an excitatory synapse onto cell # 2 , when cell #1 fires a single action potential it releases glutamate onto the membrane of cell #2 resulting in a 5 millivolt depolarization, a 5 mV excitatory postsynaptic potential, when cell #1 fires three action potentials in rapid succession this causes a 15 mV depolarization in cell #2 resulting in cell #2 reaching threshold and firing its own action potential. Cell #1 Cell #2 +40 Vm IN Cell...

What is typically the role of an inhibitory synapse? to open Na+ channels in the post-synaptic membrane to depolarize the post-synaptic membrane to generate an EPSP to hyperpolarize the post-synaptic membrane If a post-synaptic nerve cell receives a large number of EPSPs from synapses on different dendrites, what is the most likely result? A hyperpolarization Mechanical summation Spatial summation An IPSP Why might natural selection have favored cephalization? It allows animals to better detect stimuli behind them, if they are...

B) All of the interneuron cell bodies and dendrites onto which the afferent neuron synapses. C) The number of interneurons with which the central process of the afferent neuron makes synaptic contact via divergence. D) The type of stimulus energy to which the afferent neuron is most sensitive. E)...
The action potential travels down the cell's axon to initiate transmitter release at the presynaptic terminal. At the terminal, voltage-gated channels... a. allow potassium to rush into the cell, causing neurotransmitter release b. allow calcium to rush into the cell, causing a direct change in voltage in the next cell c. allow calcium to rush into the cell, causing neurotransmitter release d. allow calcium to rush out of the cell, causing neurotransmitter release
