NASM CPT 7 QUESTIONS AND
CORRECT ANSWERS
Nonaxial ANSW✅✅A gliding joint that moves in only one plane, either back and forth or side to
side.
muscular system ANSW✅✅connects the nervous and skeletal systems and generates force to
move the body
myofibrils ANSW✅✅consists of repeating sarcomeres & myofilaments Actin & Myosin, which
create muscle contraction (the Sliding Filament Theory) - ATP is needed for this
Excitation-contraction Coupling ANSW✅✅name of process of how muscle contraction involves
the nervous and muscular systems
calcium and Acetylcholine ANSW✅✅the electrolyte and this neurotransmitter are needed for the
Excitation-Contraction Coupling process
All-or-Nothing Principle ANSW✅✅this describes how a motor unit either maximally contracts or
doesn't at all
fewer innervated fibers ANSW✅✅muscles involved with fine motor skills have motor units with ...
Type 1 slow twitch muscle fibers ANSW✅✅these are smaller in size and produce less force, but
are fatigue-resistant
Type II fast twitch muscle fibers ANSW✅✅these are larger in size, produce more force, and
fatigue quickly
skeletal, cardiac, and smooth ANSW✅✅3 types of muscles
skeletal muscle ANSW✅✅type of muscle that connects to bones and creates forces that result in
movement
,fascia ANSW✅✅connective tissue that surrounds bones and muscles
epimysium ANSW✅✅the inner layer of fascia that directly surrounds an entire muscle, usually
referred to as "deep fascia"
fascicles ANSW✅✅largest bundles of fibers inside a muscle and are surrounded by perimysium
perimysium ANSW✅✅connective tissue that surrounds a muscle fascicle
endomysium ANSW✅✅connective tissue that wraps around individual muscle fibers inside a
fascicle
tendons ANSW✅✅connects muscles to bones; when it's overstretched or torn that's called a
strain
ligaments ANSW✅✅connects bone to bone; when it's overstretched or torn that's called a sprain
myofibrils ANSW✅✅the contractile components of a muscle cell, you can find Actin and Myosin
myofilaments inside of these *
actin ANSW✅✅The thin, stringlike, myofilament that acts along with myosin to produce muscular
contraction.
myosin ANSW✅✅The thick myofilament that acts along with actin to produce muscular
contraction.
sarcomere ANSW✅✅the structural unit of a myofibril made of Actin and Myosin filaments,
between two Z-lines *
motor unit ANSW✅✅a motor neuron and all the muscle fibers it innervates
, Sliding Filament Theory ANSW✅✅the idea of how Myosin (thick) and Actin (thin) filaments slide
past each other to create contraction of a muscle (shortening the entire length of the sarcomere)
Type 1 fibers ANSW✅✅muscle that's small in size, generates lower amounts of force, more
resistant to fatigue *
Type 2 fibers ANSW✅✅muscles larger in size, generates higher force, faster to fatigue
atrium and ventricle ANSW✅✅each side of the heart has 2 chambers called..
right atrium ANSW✅✅gathers Deoxygenated blood that just returned to the heat from the body,
then pumps it to the right ventricle and lungs
left atrium ANSW✅✅receives the oxygen-rich blood from the lungs and sends it to the left
ventricle which pumps it out to the body
pulmonary artery ANSW✅✅transports Deoxygenated blood from the R ventricle to the lungs
pulmonary vein ANSW✅✅transports oxygen-rich blood from the lungs to the left atrium
stroke volume ANSW✅✅the amount of blood pumped from the heart with each contraction
(ultimately the result of End Diastolic Volume - End Systolic Volume)
end-diastolic volume ANSW✅✅the amount of blood in the ventricle before contraction
end-systolic volume ANSW✅✅the amount of blood in each ventricle after contraction
cardiac output ANSW✅✅the volume of blood pumped out of the heart in 1 minute (the function
of HR and stroke volume)
arteries ANSW✅✅these vessels transport blood AWAY from the heart
