NASM CPT Final Exam Study Guide
Proprioception
(Ans – The body’s ability to to sense the relative position of adjacent parts
of the body
Ex: when walking our feet give us proprioception about the type of surface
we are on.
Mechanoreceptors
(Ans – specialized structures that recognize pressure in tissue and transmit
signals to sensory nerves.
Muscle Spindles
(Ans – sensory receptors in the muscles that are parallel to the muscle
fibers and are sensitive to change in muscle length. Spindles stretch with
muscle and sends information to CNS.
helps to prevent muscles from stretching too far or too fast
Golgi Tendon Organs
(Ans – sensory receptors that are located at the point where the skeletal
muscle fibers insert into the tendon. Sensitive to change in tension at the
rate of change
causes the muscle to relax
Epimysium
(Ans – connective tissue UNDER fascia that acts as an outer layer of the
whole muscle
Perimysium
(Ans – connective tissue acts as an outer layer of fascicles
Endomysium
(Ans – between the individual muscle fibers
Type 1 Muscle Fiber
(Ans – “slow-twitch”, smaller in size, lessforce produced, long-term
contractions (stabilization)
Type 2 Muscle Fiber
(Ans – fast twitch, larger, quick to fatigue, force and power exercises
Agonist
(Ans – PRIME MOVER, main muscles
ex: chest press-> pectoralis major
Synergist
(Ans – ASSIST PRIME MOVER,
ex: chest press -> ant deltoid, triceps
Stabilizer
(Ans – stabilizes while prime mover and assist work.
chest press -> rotator cuff
Antagonist
(Ans – Oppose Prime mover,
chest press -> posterior delt
Right Atrium
(Ans – gather DEOXGENATED blood returning to the heart from ENTIRE
BODY
Left Atrium
(Ans – gathers OXYGENATED blood coming from the LUNGS
Right Ventricle
(Ans – thin walls pumps under low pressure. Pumps to lungs
