Skeletal System Correctives



Muscular System Correctives

Directions: You are to use this sheet to both copy screen shots to and to fill out the tables. Therefore you must SAVE it to your folder. Name it with your name, the unit, and hour (example: TLeiderMusHr5). You will email me your finished corrective sheet at tal@

Complete the following self tests from the University of Mn website: Answer online and check your work! Place screen shots (showing your score) from your finished quizzes and place in your document.



#2 is Q2—omit and #6 refers to the GROUP

#2 and #10 refer to the GROUP

#1 is flexor retinaculum, #2 is Palmaris longus

#1 is gracilis—there are also some bones in this quiz. Good review!



Physiology Review/Relearning

Watch this animation and answer the questions that follow (again, provide screenshots with your score on these quizzes) #2 and #9 are fasciculi

#6, 7 are false, #8 is true

#7 is false

#2 is H-zones

#2 Ach-E #10 H-zones

Case Study:

Go to the National Center for Case Study Teaching in Science site and read the following case study that was based on a real life shark attack in 2001:

There are lots of questions to answer and you may have to use your research skills to find additional info. I cut out questions that I didn’t need you to answer so don’t be alarmed when the numbers on this sheet do not correspond to the ones online. I challenge you to try to answer as many as you can without “googling” yourself silly. Case studies (as I use them) are about the process of diagnosis not the actual diagnosis.

Look up information in your notes, text, atlas, the library, and the web about the skeletal muscle contraction and conditions. List the additional resources you use to answer the following questions:

QUESTIONS

At the start

1. What is responsible for raising Jim's heart and respiratory rate and stimulating sweating just before the race?

One minute in

1. Rowing full speed is putting new demands on Jim's body. What are these new demands and how does the body respond to them?

2. What changes in Jim's muscles promote unloading of O2 from hemoglobin for use by the muscle cells?

3. Why do Jim's muscles feel like they are burning?

4. What conflict is produced between Jim's need to keep his body cool and his need to remove nitrogenous wastes from his blood? What did he do before the race to help alleviate this conflict?

At the halfway mark

1. Since the end of the first minute, Jim has decreased the demands his muscles are making. How has he done this? And why has he done this?

2. What are the changes in his conditions as a result?

At the finish

1. Jim has stopped rowing and his muscles are now at rest. Why are his heart and breathing rates still so high?

2. Why is he sweating more now than during the race?

Back at the dock

1. What changes have occurred in the last 10 minutes to allow Jim's heart and respiratory rates to come down?

2. Why did Jim only take sips of water after the race? What could happen if he drank as much as he wanted to?
