Week 5: Discussion - Group 4

Week 5: Discussion - Group 4

Discussion Instructions:

Think about a response to all the questions listed below. Pick one and post an initial thread response. You’re required to also post a minimum of two interactive responses (to peers and/or to a follow-up question that I may present).

Choose one of the following discussion thread topics:

1. Muscular and nervous tissues are considered “excitable.” What does that mean?
2. When comparing skeletal muscle to cardiac muscle, why does skeletal muscle fatigue easily? Why doesn’t cardiac muscle fatigue easily?
3. Why would cardiac muscle cells and some smooth muscle cells continue to contract even when their nerve supply has been removed or severed?
4. ATP is essential for muscle contraction. Briefly explain the role of ATP in muscle contraction. There are 3 pathways that are used to generate ATP in the muscle. Which pathway creates the most ATP?
5. Although we don’t consciously control smooth or cardiac muscle, there are ways in which they are regulated. Which parts of the brain are responsible for this regulation?
6. The Discussion Board (DB) is an academic discussion. As such, postings (including initial andresponse postings) are expected to be substantial, to reflect application of relevant coursecontent, and to be supported with evidence from credible sources.The following guidelines should be followed unless the instructions for a particular DBspecifically indicate otherwise:
7. One initial posting and 2 response postings are required, as a minimum, for each

discussion forum/board. Posts must be completed on at least two separate days.

8. Original posts should consist of at least 150 words (unless the assignment instructions are

different). Try not to exceed 300 words; however, no points will be deducted for longer

postings.

9. Response postings should consist of at least 75 words. Try not to exceed 300 words;

however, no points will be deducted for longer postings.

10. Timeliness is essential in the online discussion environment in terms of encouraging and

facilitating the exchange and development of ideas among members of the discussion

group. Nightingale College’s academic week runs from Monday at 12:00 am Mountain

Time (MT) to Sunday at 11:59 pm MT. All assignments for the week are due within the

academic week in which they are assigned, unless otherwise specified. Accordingly,

o Initial postings should be posted no later than Wednesday at 11:59 PM MT.

o The required response postings must be posted no later than Sunday at 11:59 PM

MT.

o The DB will officially close at 11:59 PM MT on Sunday and response postings

will not earn credit after this time.

▪ References should be included when applicable. References should be

formatted in a manner generally consistent with APA guidelines; however,

no points will be deducted for variations in line spacing and or indentation

(including "hanging" position for the first line of each entry).

▪ To avoid loss of content while your posting is under development, you

may wish to develop your postings in a MS Word document and then cut

and paste them into the DB. Please do not present your discussion

posting in the form of a MS Word document attachment.
