Excitation of the Skeletal Muscle Fiber
Skeletal muscle fiber contraction begins with
excitation of the fiber by a somatic motor neuron. The nerve signal must first cross the neuromuscular junction to excite the muscle fiber. Excitation depends on a complex sequence of events that is reviewed in Chapter 10 of your textbook. This week’s assignment will give you practice describing these events.
Begin your paper with a description of the neuromuscular junction. What are the main structural features of the motor neuron and skeletal muscle fiber where the two meet? Then address the following topics:
Starting with an action potential traveling down the axon of the motor neuron, how is the signal transmitted across the synaptic cleft to the muscle fiber?
How is an End Plate Potential generated?
How is an action potential initiated and propagated to the sarcoplasmic reticulum?
What happens at the sarcoplasmic reticulum that leads to a contraction?
How does the structure of a skeletal muscle fiber enable contraction to occur?
Requirements:
Your paper should be 2 pages in length, excluding title and reference pages.
Include at least two scholarly references, in addition to the course textbook. Also cite your sources in the body of the paper.
Conform to the APA guidelines in the CSU Global Writing Center.
The CSU Global Library is a good place to find these references.

Research and discuss one of the following topics in the US (be sure to reference your source of information). Be sure to include: epidemiology (prevalence/incidence, risk factors), signs and symptoms, diagnosis, treatment, and prognosis. Include minimum two images embedded in your post. Note: do not attach a file as your post. Use the text box and the images icon to formulate your post. Congestive heart failure
Research this disease and tell us about certain aspects of the disease. Make sure to include:
Origin of the name
Etiology
Epidemiology (incidence or prevalence rates, populations affected (age, gender, ethnicity, regions))
Signs and symptoms
Diagnosis
Treatments
Prognosis
Each section of your post should contain these headings. Include at least two pictures in your post (i.e. an unusual sign and/or symptom, a chart, a graph, a diagnostic tool). Use the Insert/Edit Image icon; do not include your picture as an attached file.
Some of these diseases affect other organ systems as well; please mention these systems but mostly focus on their effects on the homeostatic effects since that is this module’s topic.
Warning: Do not copy and paste from online sources. Create original descriptions using words from your A&P vocabulary that you have learned this semester. Cite your sources at the end of your post.
There is a 400-word count minimum for your post.

hello, i am taking anatomy and physiology 2 and i need a B or higher to pass this class but unfortunately i took my final today and got an F which brought me down to a 77%, i was wondering if you could write an email for my profesor and let her know that i really did try and i need my B and higher to get into my program this fall ( this class is the only one i need to get into it) if there’s anything i can do to but if not well i understand but it was worth a try.

I need a pathophysiology paper done on bursitis. I will have to submit the final draft through a plagiarism website to be checked before submission. This is for my anatomy and physiology class. It must have intext citations as well as references to match. I will do my own title page so the 5-6 pages need to be the actual content and the last page is for the reference page. Thanks
