Section Title: Anatomy of Skeletal MuscleLearning Outcome: 9.3Bloom's Taxonomy: Comprehension
2) How do the different connective tissues of the muscles relate to one another?3) Describe the arrangement within a myofibril.4) Why does a sarcomere appear to be banded, and of what are the bands composed?5) How do calcium ions effect the changes leading to muscle contraction?Answer: Calcium ions are constantly transported out of the sarcoplasm and into the sarcoplasmic reticulum to be released when electrical changes occur in the membranes of the T tubules. The duration of the contraction depends upon the duration of the electrical events.Section Title: Muscle ContractionLearning Outcome: 9.5Bloom's Taxonomy: Comprehension6) How is muscle contraction regulated by tropomyosin and troponin?
7) How does the sliding mechanism of the sliding filament theory work?
