    What is the role of the SA Node in cardiac conduction?

    Initiates the electrical impulse for heart contraction.

    How does the AV Node function in cardiac conduction?

    Delays the impulse to allow ventricles to fill with blood.

    What happens after the Bundle of His in cardiac conduction?

    Impulses split into left and right bundle branches.

    What is the function of Purkinje fibers?

    Distribute the electrical signal throughout the ventricles.

    What defines a hinge joint?

    Allows movement in one plane, like flexion and extension.

    How do ball and socket joints differ from hinge joints?

    Ball and socket joints allow multi-directional movement.

    What is wave summation in muscle contractions?

    Increased force due to repeated stimulation of motor units.

    What is the consequence of tetanic contractions?

    Results in smooth, sustained muscle contractions.

    What is the role of muscle spindles?

    Detects muscle stretch and initiates a reflex response.

    What does autogenic inhibition cause?

    Sudden relaxation of a muscle under tension.

    What is partial pressure in gases?

    Pressure exerted by a single gas in a mixture.

    How does diffusion occur in gases?

    Molecules move from high to low concentration areas.

    What is atherosclerosis?

    Hardening and narrowing of arteries due to plaque buildup.

    What happens during vasodilation?

    Blood vessels widen, increasing blood flow.

    What is the difference between systole and diastole?

    Systole is heart contraction; diastole is heart relaxation.

    What does EPOC stand for?

    Excess post-exercise oxygen consumption.

    What is the Cori Cycle?

    Converts lactic acid to glucose in the liver.

    What defines VO2 max?

    Maximum oxygen uptake during intense exercise.

    What is the impact of altitude training?

    Increases red blood cell count and oxygen transport.

    What characterizes Type I muscle fibers?

    High aerobic capacity and low fatigue.

    How do Type IIx muscle fibers differ from Type I?

    Higher force production and faster contraction speed.

    What is a closed skill?

    Not affected by the environment, like archery.

    What is positive transfer in skill learning?

    Learning one skill aids in learning another.

    What is the purpose of mental practice?

    Cognitive rehearsal to enhance physical skill performance.

    What is the effect of negative reinforcement?

    Removal of criticism when correct technique is shown.
