NESTA PFT Exam Prep Questions and answers, 100% Accurate, rated A+ What are the four steps in "Bridging the Gap"? - ✔✔-Assess, Design, Instruct, Re-assess What is an implicit goal? - ✔✔-Im... plied but not mentioned What is an explicit goal? - ✔✔-Goals that are mentioned What is the kinetic chain, and what is it's function? - ✔✔-Composed of nervous system, muscular system, and skeletal system. Chain of systems that link together to create human movements. What is smooth muscle tissue? - ✔✔-Involuntary actions (digestive tract, bladder, uterus, blood vessel walls) No striations What is cardiac muscle tissue? - ✔✔-Involuntary but has some striations; Heart What is skeletal muscle tissue? - ✔✔-Voluntary movements; all muscles controlling movements What are the three layers of muscle fascia? - ✔✔-Epimysium (outer), perimysium, endomysium (inner) What is mechanoreceptors? - ✔✔-Respond to touch, pressure, vibrations, or stretch. What is thermoreceptors? - ✔✔-Respond to changes in temperature. What is nociceptors? - ✔✔-Respond to painful stimuli. What is photoreceptors? - ✔✔-Respond to light to allow vision. What is chemoreceptors? - ✔✔-Respond to chemical stimuli (food odors, carbon dioxide, glucose). What is the function of the somatic nervous system? - ✔✔-Innervates skeletal muscle to create movement via motor neurons. Always excitatory. What is the sympathetic nervous system? - ✔✔-"Fight or flight" Blood pressure/heart rate increase, digestive slowing. What is the parasympathetic nervous system? - ✔✔-"Rest and digest" Blood pressure/heart rate decrease, digestive increases. What is the structure of the motor unit? - ✔✔-Motor neuron, muscle fibers, motor end plates What is the sliding filament theory? - ✔✔-Elements will slide over each other; sarcomeres shortening together, causing muscle to contract as a whole. What is the role of the Myosin ATPase in a muscle action? - ✔✔-Interactions of actin and myosin during muscle contraction. How does the Myosin head bind to the Actin filaments in a muscle action? - ✔✔-Slide and overlap What is the role of the prime mover (agonist)? - ✔✔-Acts directly to bring about a desired movement. What is the role of the assistant mover (synergist)? - ✔✔-Assists indirectly to bring about a desired movement. What is the role of the antagonist? - ✔✔-Opposes the concentric muscle action of agonist (more susceptible to injury). What is the role of the stabilizer? - ✔✔-Responsible for stabilizing. What is the role of the neutralizer? - ✔✔-Responsible for eliminating and canceling out undesired movement. What is the Type I muscle fiber? - ✔✔-Red, slow twitch, aerobic fibers (endurance; longer than 3 minutes). What is the Type IIA muscle fiber? - ✔✔-Pink, moderately fast twitch (strength; 30 seconds - 2 minutes). What is the Type IIB muscle fiber? - ✔✔-White, fast twitch, anaerobic fibers (1RM, hypertrophy, explosive movements). What is hypertrophy? - ✔✔-Increase in size of myofibrils What is hyperplasia? - ✔✔-Increase in number of muscle cells What is atrophy? - ✔✔-Wasting/loss of muscle due to disease/lack of use What are the various types of strength? - ✔✔-Absolute strength, relative strength, strength endurance, power In which bone will you find the diaphysis? - ✔✔-Long bone What occurs in epiphyseal plate slippage? - ✔✔-Inhibits the growth of bone at joint, but will not affect growth of body. What is the synarthroial joint? - ✔✔-Immovable joint (pelvis) What is the amphiarthroses joint? - ✔✔-Semi-movable joints (sacroiliac & pubis) What is the diarthrodial joint? - ✔✔-Freely movable joints (hip & knee) What is ATP? - ✔✔-Adenosine triphosphate; source of energy for muscular contraction. Lactic Acid is a byproduct of which energy system? - ✔✔-Anaerobic system What is aerobic exercise? - ✔✔-With oxyge [Show More]
