Question 1

rotary motion

Answer 1

movement around an axis and implies that the levers (bones) rotate around the axis (joints)

Question 2

torque

Answer 2

force that produces rotation; turning effect of the joint

Question 3

flexion

Answer 3

bending movement; decreases relative angle between segments

sagittal plane

bicep curl, tricep pushdown, squat

Question 4

extension

Answer 4

straightening movement; increases relative angle between segments

sagittal plane
bicep curl, tricep pushdown, squat

Question 5

plantarflexion

Answer 5

extension at the ankle

sagittal, toes pointed toward ground

Question 6

dorsiflexion

Answer 6

flexion at the ankle, sagittal, toes flexed

Question 7

abduction

Answer 7

movement in frontal plane away from the middle

frontal plane
side lateral raise, side lunge, side shuffle

ab duck station- a duck kidnaps a kid, takes it away from its home

Question 8

adduction

Answer 8

movement in frontal plane toward the middle

frontal plane
side lateral raise, side lunge, side shuffle

Question 9

horizontal abduction

Answer 9

transverse plane arm movement from anterior to lateral

transverse plane
chest flies

Question 10

horizontal adduction

Answer 10

transverse plane arm movement from lateral to anterior

transverse plane
chest flies

Question 11

internal rotation

Answer 11

rotation toward the middle of the body

transverse plane
throwing, golfing, swinging a bat, trunk rotation

Question 12

external rotation

Answer 12

rotation away from the middle of the body

transverse plane
throwing, golfing, swinging a bat, trunk rotation

Question 13

Concentric

Answer 13

moving in opposite direction of force, accelerates or produces force; muscle shortens

Question 14

Eccentric

Answer 14

muscle develops tension while lengthening; decelerates force; the “negative”; landing from a jump, lowering of squat

Question 15

Isometric

Answer 15

muscular force equal to resistive force, stabilizes force; no change in muscle length

Question 16

sagittal plane

Answer 16

flexion/extension

coronal axis

Question 17

frontal plane

Answer 17

adduction/abduction, lateral flexion, eversion/inversion

anterior-posterior axis

Question 18

transverse plane

Answer 18

internal, external, left/right rotation; horizontal adduction and abduction

longitudinal plane

Question 19

length-tension relationships

Answer 19

resting length of a muscle and the tension it can produce at that length

myosin and actin overlap

Question 20

force-couple relationships

Answer 20

muscles working together to produce movement

Question 21

sagittal plane types of motion

Answer 21

flexion/extension

biceps curl
triceps pushdown
squat
calf raise
walking running
jumping
climbing stairs

Question 22

frontal plane types of motion

Answer 22

adduction/abduction
lateral flexion
eversion/inversion

side lat raise
side lunge
side shuffle

Question 23

transverse plane types of motion

Answer 23

internal rotation
external rotation
left/right rotation
horizontal adduction
horizontal abduction

trunk rotation
throwing
golfing
swinging a bat

Question 24

what are poor posture and misaligned joints caused by?

Answer 24

altered length-tension relationship

Question 25

one of the muscles associated with multiple different muscle imbalances

Answer 25
