Questions
Bones contain... Right Ans - 98% of body's calcium
Osteoporosis Right Ans - A condition in which the body's bones become
weak and break easily.
Axial skeleton Right Ans - skull, hyoid bone, vertebral column, and rib cage
Appendicular skeleton Right Ans - the limbs and their respective girdles
Bone mass is usually attained by about...
while BMD can be improved until around Right Ans - age 18 and 30
Epiphyseal plate Right Ans - transverse cartilage plates located near the
end of long bones are responsible for increases in vertical growth during
childhood/adolescence
Synovial joint Right Ans - uses synovial fluid to reduce frictional stresses
and allow for considerable movement between the associated articulating
bones
mostly of the appendicular skeleton
Ligament Right Ans - fibrous bands of connective tissue that support
internal organs and hold bones together at joints
Tendons Right Ans - fibrous band of connective tissue that connects
muscles to bones
Plane joint Right Ans - short slipping or gliding movements; i.e. carpals
Pivot joint Right Ans - found in neck and forearm
Hinge joint Right Ans - found in knees, elbows, fingers, and toes
Condyloid joint Right Ans - found in the wrist
, Saddle joint Right Ans - Only in the thumb
Ball-and-Socket joint Right Ans - found in shoulders and hips
Skeletal Muscle, Cardiac Muscle, Smooth Muscle Right Ans - 3 types of
muscle tissue
Muscle Fascia Right Ans - fibrous connective tissue that encapsulates full
muscles as well as bundles of fibers; provides the muscle's shape and
regulates tension/transfer of force across joints
Asynchronous firing Right Ans - employed during endurance activities
involving slow-twitch fibers which conserve motor unit potential, allowing
prolonged work
Synchronized firing Right Ans - employed during high-output demands
involving fast-twitch fibers and warranting significant fiber recruitment
Agonist-antagonist relationships Right Ans - help facilitate smooth force
production; one muscle contracts while the muscle on the opposite side of the
joint relaxes (neural regulation)
Agonist Right Ans - muscle that contracts/shortens during a given exercise
(e.g., biceps during a curl)
Antagonist Right Ans - muscle that relaxes and lengthens during a given
exercise to accommodate contraction of the agonist (e.g., triceps during a
biceps curl)
Isotonic Right Ans - tension remains constant while joint angles change;
seen during most exercises that include an acceleration and deceleration
component
Concentric Right Ans - occurs during the acceleration phase of a lift as the
muscle shortens
Eccentric Right Ans - occurs during the deceleration phase of a lift as the
muscle lengthens
