ISSA Strength and Conditioning Final Exam Questions And Answers Sliding Filament Theory - ANS Actin filaments at each end of the sarcomere slide inward on myosin filaments, pulling z-lines toward the center of the sarcomere and thus shortening the muscle fiber. Muscle fiber fatigue order - ANS Type 2a Type 2x Type 1 lactic acid - ANS Produced in muscle cells from the reduction of pyruvate (under anaerobic conditions) to regenerate NAD+ so that glycolysis can continue. A ris...

1. According to the sliding filament theory, what is the initial action in a muscle contraction? a. Troponin is freed and prevents actin and myosin from reacting with each other. b. Calcium binds to troponin, which causes the release of actin and myosin binding sites. c. Actin and myosin molecules react with each other sliding along the filament and making it shorter. d. Muscle filament relaxes or slides back to the resting position. Ans: C Feedback: Actin and myosin molecules react wi...

Medial - the midline of the body distal - further away from the midline of the body proximal - closer to the midline of the body ipsilateral - on the same side of the body contralateral - on the opposite side of the body inferior - below the midline superior - above the midline anterior - front of the body posterior - back of the body Golgi Tendon Organs - Senses Muscle Tension Relaxes muscle in response Normal reaction to avoid injury Structure of the heart - Hollow, muscular organ ...

Pre-Lab Questions 1. How do banding patterns change when a muscle contracts? When a muscle contracts, the banding patterns within the muscle change due to the sliding filament theory of muscle contraction. This theory suggests that muscle contraction occurs when thin filaments (actin) slide over thick filaments (myosin), resulting in the overlapping of these filaments and shortening of the sarcomeres, which are the basic contractile units of the muscle. As a result, the dark A bands, which...

Name the first regression of a squat? - Leg press 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) 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) Where is the biceps femoris located? Name an opposing muscle - located in the lateral side of hamstring, rectus femoris Name t...
