1. Skeletal Muscle Anatomy

2. Skeletal Muscle Fiber
Skeletal Muscle Fiber: single cell that contracts in response to stimulation or relaxes when the stimulation ends

3. Parts of the Skeletal Fiber
Sarcolemma- cell membrane
Sarcoplasm- cytoplasm
Myofibrils- threadlike protein filaments
Myosin- thick filaments
Actin- thin filaments
Altering myosin/actin is what causes striations in skeletal muscle fibers

4. Organization of Muscles

5. Other Structures Sarcoplasmic reticulum: like ER
Transverse Tubules: help with muscle contraction

6. Arrangement of Muscle Fibers

7. Make a model
On a sheet of paper, use available supplies to make a model of a sacromere.
Label- myosin/actin and the bands that we went over.
