week 1 biomechanics terminology

Question 1

kinematics

Answer 1

characteristics of motion through space and time
e.g position, velocity, acceleration, angle

Question 2

linear motion

Answer 2

all systems parts are moving in the same direction at the same speed (translation)
motion along a straight line- rectilinear
along a curved line- curvilinear

Question 3

angular motion

Answer 3

motion around central axis of rotation- which are perpendicular to the plane of rotation

Question 4

kinetics

Answer 4

describes the actions of forces associated with the motion

Question 5

away and towards centre

Answer 5

<—–/—–> lateral
——>/<—— medial

Question 6

up and down from centre

Answer 6

superior (up)
inferior (down)

Question 7

backwards and forwards from centre

Answer 7

posterior/dorsal (back)
anterior/ ventral (forward)

Question 8

further and closer to the trunk

Answer 8

proximal- towards the trunk
distal- further from the trunk

Question 9

sagittal plane

Answer 9

vertical plane which passes through the body longitudinally-divides into left and right

Question 10

frontal plane

Answer 10

vertical plane running side to side, divides body into anterior and posterior

Question 11

transverse plane

Answer 11

horizontal plane, divides body into superior and inferior

Question 12

joint movement terminology- flexion

Answer 12

decease in the angle of the joint

Question 13

joint movement terminology- extension

Answer 13

increase in the angle of the joint

Question 14

joint movement terminology- abduction

Answer 14

movement of the limb away from the midline

Question 15

jmt- adduction

Answer 15

movement of the limb towards the midline

Question 16

jmt- pronation

Answer 16

movement of hand and forearm to bring the palm facing posterior

Question 17

jmt- supination

Answer 17

movement of hand and forearm to bring the palm facing anterior

Question 18

jmt- circumduction

Answer 18

circular movement of a joint

Question 19

jmt- internal/medial rotation

Answer 19

rotation of a limb medially

Question 20

jmt- lateral/ external rotation

Answer 20

rotational movement of a limb laterally

Question 21

jmt- eversion

Answer 21

movement of the sole of the foot away from the medial plane

Question 22

jmt- inversion

Answer 22

movement of the sole of the foot towards the medial plane

Question 23

jmt- dorsiflexion

Answer 23

movement of the foot in a dorsal direction

Question 24

jmt- plantarflexion

Answer 24

movement of the foot in a ventral direction

Question 25

statics

Answer 25

no movement or systems in a constant state of motion

Question 26

dynamics

Answer 26

systems subject to acceleration
