KIN 3309 Midterm 1 Study Guide
Quiz questions based on the Chapter readings (somewhat paraphrased)
o When the body is in anatomical position, the palms face towards the front of the
body (in the direction of observant of the position).
o It is true that when the body is in fundamental position the thumb will be on the
anterior side of the hand.
o Biomechanics is best described as the study of the structure and function of
biologic systems by means of the methods of mechanics.
o The right and left deltoid muscles are contralateral to one another. o An example of a quantitative analysis is using a platform to measure the forces
imposed on the feet during walking.
o The upper extremities are not a part of the axial skeleton.
o The wrist is not proximal to the elbow. (it is distal)
o A relative angle can also be referred to as a joint angle.
o It is true that when the body is in fundamental position, the thumb is on the
anterior side of the hand.
o If one clasps his hands behind his back and moves them back and upward, the
term that best describes his movement at the shoulder joint is hyperextension. o An example of a kinematic analysis is the examination of the projectile
characteristics of a high jumper.
o Holding the hand in a fixed position and drawing an imaginary O in the air with
the thumb is best described as circumduction.
o During eccentric contraction is when we can achieve the greatest muscle force
possible. Don't forget about the age old question of Multidomestic company is what?
o The term that best describes an exercise for the quadriceps that is a simple squat
movement with the feet on the floor is “closedchained”.
o Tendons connect to the muscle at the myotendinous junction.If you want to learn more check out Which sex is the homogametic sex in humans?
o The success of a strength training program is largely dependent on the intensity of the training, the volume of the work performed, and the amount of rest between
o The muscles that are at greatest risk for a strain are twojoint muscles, muscles
that limit range of motion, and muscles used eccentrically.
o It is true that body builders use the short rest and highintensity training to build up the size of the muscle at the expense of losing some strength achieved with a
longer rest period.
o If a second stimulus occurs in a motor unit before the first twitch has subsided, the Don't forget about the age old question of What is effective strategy?
muscle WILL respond to the second stimulus.
o In a myofibril, the dark bands are myosin and the light bands are actin. o Overstretching the muscles does not create muscle laxity.
o Calcium ions that are released into the area surrounding the myofibrils do
promote crossbridge formation.
o A form of isotonic exercise is lifting free weights.
o In the sliding filament theory, the actin and myosin slide past one another during If you want to learn more check out What is euploidy?
o Local graded potential, like the action potential, maintains its amplitude as it
travels along. (false)
o The muscle fibers in a single motor unit cannot vary in type.
o Proprioceptors are the primary sensory receptors for the musculoskeletal system
that alert the CNS of joint position, muscle length, and muscle tension. o Bone density does not affect joint range of motion.
o The following statements about proprioceptive neuromuscular facilitation (PNF)
PNF stretching promotes relaxation of the stretched muscle so that the
joint can be moved through a greater range of motion.
PNF stretching is frequently used in rehabilitation settings.
o Singleleg bounds are an example of plyometrics.
o In small muscles, at 30% to 50% of the maximum voluntary contraction all motor
units are recruited.
o Tetanus refers to the result of many twitches summed together and constant We also discuss several other topics like Demonology and witchcraft are considered the first form of?

tension in the muscle fiber.
o To reduce the risk of injury, the following precautions should be taken in regard
Plyometrics should be done on yielding surfaces.
Plyometrics should not be done more than two days per week.
One should establish a strength base before engaging in plyometric
o The neurologic basis for plyometrics is the input from the stretch reflex via type la
o The tibialis posterior is part of the triceps surae.
o “Pes planus” is another term for classifying arches as “flat feet”.
o In addition to knee flexion and extension movements, knee structure also allows
for internal and external rotation.
o The vastus intermedius, is the middle part of the muscle group of the quadriceps
muscle that cannot be palpated.
o The anterior cruciate ligament prevents the tibia from moving anteriorly relative to the femur.
