Canfitpro FIS Chapter 5 questions with
100% complete solutions
Isotonic concentric contraction - correct answer ✔✔The movement when a muscle contracts to shorten
isotonic eccentric contraction - correct answer ✔✔The movement when a muscle contracts to lengthen
Isometric contraction - correct answer ✔✔Muscle contracts but remains static. There is no change in
muscle length.
Muscle Types (3) - correct answer ✔✔skeletal, cardiac, smooth
Myofibril - correct answer ✔✔tightly packed filament bundles found within skeletal muscle fibers
Sarcomere - correct answer ✔✔a structural unit of a myofibril consisting of two types of protein (actin
and myosin)
Sliding Filament Theory - correct answer ✔✔the concept that a sarcomere shortens as the thick and thin
filaments slide past one another and they completely overlap
Actin - correct answer ✔✔Thin filament of protein found in muscles
Myosin - correct answer ✔✔Thick filament of protein found in muscles
central nervous system - correct answer ✔✔consists of the brain and spinal cord
Perioheral nervous system - correct answer ✔✔the sensory and motor neurons that connect the central
nervous system (CNS) to the rest of the body.
