1. Myocyte Muscle cell 2. Sarcolemma Plasma membrane of myocyte 3. Sarcoplasm Cytoplasm of myocyte 4. Myofibril Tightly packed filament bundles found within skeletal muscle fibers. Contractional unit of a muscle cell. 5. Sarcoplasmic reticulum Site of calcium storage in a muscle cell. Surrounds the myofibrils 6. Transverse tubules (T-tubule) Inward extensions of the sarcolemma that dive into the muscle fiber and surround each myofibril to form a tunnel- like network within the musc...

1. Name the first regression of a squat?: Leg press 2. What is PROM and APROM?: passive range of motion (someone helps you do the movement) and active range of motion (you do the movement on your own) 3. What are the two protein filaments that slide over each other during a muscle contraction (sliding filament theory): actin (thin filaments) and myosin (thick filaments) 4. Where is the biceps femoris located? Name an opposing muscle: located in the lateral side of hamstring, rectus femoris 5...
