Question 11

force that causes tension

Answer 11

pull

Question 12

components of force vector

Answer 12

point of application
direction
magnitude

Question 13

linear force

Answer 13

two or more forces acting along the same line

ex: gastrocnemius and soleus

Question 14

concurrent force

Answer 14

two or more forces actin on a common point pushing or pulling in different directions

ex: deltoid

Question 15

parallel force systems

Answer 15

occurs in the same plane and in the same or opposite direction

ex: sternocleidomastoids, external obliques

Question 16

force couple

Answer 16

occurs when two or more forces act in different directions, resulting in a turning effect

ex: scapula rotation

Question 17

four components of levers

Answer 17

a rigid bar/bone
an axis or fulcrum, point of rotation/joint
a resistance force
an effort force

Question 18

effort force and resistance are on either side of the axis

Answer 18

first class lever

Question 19

effort fore and resistance force are on the same side of the axis

resistance force lies between the effort force and the axis of rotation

Answer 19

second class lever

Question 20

effort force and resistance force are on the same side of axis

effort force lies between the resistance force and the axis

Answer 20

third class lever

Question 21

rotation of the lever depends on ____

Answer 22

magnitude of the force and distance from the axis

Question 23

how is torque calculated

Answer 23

lever arm x Fy
Fm x movement arm

Question 24

a movement’s magnitude depends on

Answer 24

force applied
force’s movement arm

Question 25

depicted as a vector with a line of application

Answer 25

force applied

Question 26

the perpendicular distance from the force's line of application to the axis of rotation

Answer 26

force's movement arm

Question 27

assessment of movement

Answer 27

strength ROM

Question 28

how to palpation

Answer 28

feel bony landmarks and soft tissue around the joint use pads of index and middle finger to palpate avoid contact with fingernails apply pressure gently but firm enough to feel underlying muscle, tendon, bones

Answer 37

ligaments to joint capsule

Question 38

occurs when ROM is increased or decreased or when ROM is normal but structures other than normal anatomy stop inflammation, pain, fracture, etc.

Answer 38

abnormal end-feel

Question 39

MMT can measure

Answer 39

muscle strength and maximal muscle contractions
