Objectives: Review major concepts of the muscular system
What we did:
TEST FRIDAY Objectives: Review major concepts for the Muscle unit
What we did:
Objectives: Review muscle origin/insertions/movements, ATP energy sources, and the process of Muscle Contraction.
What we did:
Objectives: review the steps of nerve impulse to contraction, and practice ATP energy sources concepts.
What we did:
Objectives: Review the steps that occur at the neuromuscular junction and within the sarcomere.
What we did: We cut out the steps on the handout Nerve Impulse to Contraction Ordering Steps Activity and practiced putting the steps in order. First individually, then with a partner, then using any resource (textbook, notes, etc.) Then, we worked in groups of 2 or 3 to complete the Nerve Impulse to Contraction Flow Chart. Given the word-bank, recreate the flow chart to the best of your ability without referencing any notes, and then check your answers and correct them. The handout "Notes over Muscles, ATP, Muscle Fatigue, Isontonic, and Isometric Contractions" was given to everyone to help summarize Thursday's material. Objectives: Practice and understand ATP sources in muscle contraction
What we did:
Objectives: review the steps of the neuromuscular junction, the sliding filament theory of muscle contraction, and make the connection between the two by introducing the role of the sarcoplasmic reticulum.
What we did: We took time in groups of two or three to write down the steps of the intramuscular junction. Then we collaborated as a class to make the best summary we could of the steps on the whiteboard (picture). Then we watched 1:00-3:28 of Muscle Contraction Video to review Sliding Filament Theory, paying close attention to the roles of the Calcium ion and ATP. Finally, we connected the action potential spreading across the sarcolemma, to the release of calcium that triggers muscle contraction in the sarcomere: Calcium is stored in the sarcoplasmic reticulum, and the action potential causes it to be released into the sarcomeres. (picture shown in class) Objectives: Learn about types of energy resources in muscles.
What we did: Talked about these slides about ATP in muscles. Used the last 10 minutes of class to review muscle names and motions. Objectives: become familiar with the sensation of muscle fatigue to prepare for learning about energy supply and muscle contraction.
Make-Up Work Instructions: Complete the exercises and record all data for the Muscle Fatigue Lab, and complete the reflection questions on the final page. When you return, turn in to Make-up work folder. |
