NPTE-PTA EXAM QUESTIONS AND
ANSWERS
What energy system is used for APT production during high intensity, short duration
exercises (sprinting 100 m)? - Answer-ATP-PC system
How long does the ATP-PC system provide energy for muscle contraction? - Answer-15
seconds
This energy system is a major supplier of APT during high intensity, short duration
activities such as sprinting 400 or 800 m? - Answer-Anaerobic Glycolytic system
What forms with the anaerobic glycolytic system? - Answer-Lactic acid
How long is the anaerobic glycolytic system last? - Answer-30-40 seconds of muscle
contraction
What system is used predominantly during low-intensity long duration exercise (such as
running a marathon)? - Answer-Aerobic system
How long will the Aerobic system provide energy for? - Answer-as long as there are
nutrients to utilize
How does the frontal plane divide the body? - Answer-into anterior and posterior
sections
How does the sagittal plane divide the body? - Answer-into right and left sections
How does the transverse plan divide the body? - Answer-into upper and lower sections
What is a class 1 lever? - Answer-axis of rotation is between the effort (force) and
resistance (load)
What is a class 2 lever? - Answer-resistance (load) is between the axis of rotation
(fulcrum) and the effort (force); effort arm is always longer than the resistance arm
wheelbarrow.
What is a class 3 lever? - Answer-the effort (force) is between the axis of rotation
(fulcrum) and the resistance (load). Permit large movements at rapid speeds and are
the MC type of lever in the body.
ex: shoulder abduction w/ weight at the wrist, elbow flexion
, What is a fibrous joint? - Answer-composed of bones that are united by fibrous tissue
and are non-synovial. movement is minimal to non
What is a cartilaginous joint? - Answer-Have hyaline or fibrocartilage that connects one
bone to another. they are slightly moveable joints
what are Synovial joints - Answer-Provide free movement between the bones they join
What is the muscle spindle? - Answer-within the belly of muscles.
sends information about muscle length and/or the rate of change of its length.
Important in the control of posture.
What is the function of the Golgi Tendon Organ? - Answer-Sensing muscle tension at
the Musculotendinous insertion
What part of the glenohumeral joint is convex? concave? what kind of joint is it? -
Answer-convex head of the humerus and concave glenoid fossa of the scapula
ball and socket synovial joint
unstable joint
What forms the sternoclavicular joint? - Answer-medial end of the clavicle and the
manubrium of the sternum
What makes up the acromioclavicular joint? What is this joint's function? - Answer-
acromion process of the scapula and the lateral end of the clavicle
to maintain the relationship between the clavicle and scapula during GH ROM
What makes up the scapulothoracic articulation? - Answer-body of the scapula and the
muscles covering the posterior chest wall
What muscles do shoulder flexion? - Answer-Anterior delt, coracobrachialis, pec major
(clavicular head, biceps brachii
What muscles do shoulder extension? - Answer-lats, post delt, teres major, tricpes
brachii (long head)
What muscles do shoulder abduction? - Answer-middle delt, supraspinatus
What muscles do shoulder adduction? - Answer-pec major, lats, teres major
What muscles do shoulder lateral rotation - Answer-teres minor, infraspinatus, posterior
delt
What muscles do medial rotation at the shoulder? - Answer-subscap, teres major, pect
major, lats, ant delt
