Sequencing
Indicate the Proper Sequence of Events at the Neuromuscular

question 24

Short Answer

Sequencing
Indicate the proper sequence of events at the neuromuscular junction by filling in the blank with the appropriate number from 2 through 7. Numbers 1 and 8 are already identified.
$\begin{array}{|l|l|}\hline &\text {AChis released from the axon terminal by exocytosis. } \\\hline &\text {AnEPP takes place, primarily as a result of \( \mathrm{Na} \) influx. } \\\hline 8 &\text {A cetylcholinesterase inactivates \( \mathrm{ACh} \), terminating activity at the neuromuscular junction } \\\hline 1&\text {An action potential is propagated to an axon terminal of a motor neuron } \\\hline &\text {Channels that permit passage of \( \mathrm{Na}^{+} \)and \( \mathrm{K} \) are opened in the motor end plate. } \\\hline &\text {\( \mathrm{Ca}^{2+} \) channels are opened in the axon terminal. } \\\hline &\text {Local current flow between the motor end plate and adjac ent mus de-cell membrane initiates an action potential that spreads } \\&\text { throughout the muscle fiber. }\\\hline &\text {ACh binds with receptor sites on the motor end plate. } \\\hline \end{array}$

Definitions:

Dependent Variable

the variable in a study or experiment that is expected to change in response to manipulations of the independent variable.

Self-Reported Mood

A method of assessment where individuals describe their current mood state or feelings typically through questionnaires or interviews.

Independent Variable

The variable in an experiment that is manipulated or changed to observe its effect on the dependent variable.

Dependent Variable

In an experiment, it is the variable that is tested and measured, potentially being affected by the manipulation of the independent variable.
