Flashcards in Chapter 5 Deck (59):
1

Name the 3 planes of motion

Sagital, frontal, and transverse

2

Divides body into right and left half. Flexion and extension. Walking, squatting, curling, ab crunches

Sagital plane

3

Divides body into back ad front. Side to side motions. Adduction or abduction, Lateral flexion, inversion, eversion (Lateral raises, side lunges, side shuffles)

Frontal Plane

4

Divides body into top and bottom half. Rotation motions and horizontal adductions. (Spine rotation, shoulder rotation, Hip rotation, throwing, golfing, swinging a bat)

Transverse Plane

5

Force is produced, muscle tension is developed, and movement occurs through a given range of motion. "constant tension"

Isotonic

6

3 muscle actions

Concentric, isometric, and eccentric

7

moving in the same direction as the resistance. Decelerates. Reduced force

Eccentric

8

Moving in the opposite direction of force. Accelerates, Produces force

Concentric

9

No movement with or against resistance. Dynamically stabilizes force.

Isometric

10

The speed of mvmnt is fixed and resistance varies with the force exerted. Requires special equipment.

Isokinetic

11

Tension while shortening or accelerating

Concentric

12

Tension while lengthening or deceleration

Eccentric

13

Muscle groups moving together to produce a joint movement

Force couple

14

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

Length tension relationship

15

Movement of bones around joints

rotary motion

16

Force that produces rotation

Torque

17

Difference between external and internal feedback

Internal: uses sensory info for feedback
External: provided by an outside source

18

Muscles ability to produce tension @ differing shortening velocities

Force velocity curve
Concentric = decreases force production
eccentric= increases " "

19

Misaligned joints Like tight quads preventing the hamstrings from using appropriate force is an examples of

altered length relationship

20

Science concerned with internal and external forces and the effects produced by these forces

Biomechanics

21

Above reference point

Superior

22

Below reference point

Inferior

23

Closest to reference point

Proximal

24

Furthest from reference point

distal

25

Front

Anterior

26

Back

Posterior

27

Towards mid line

medial

28

Away from midline

Lateral

29

Opposite side of body

contralateral

30

Same side of body

Ipsilateral

31

Body erect, arms by side, palms forward

Anatomic

32

Rt and left plane

sagital

33

Bending movement; relative angle b/w two adjacent segments decrease

Flexion

34

Bending movement segment angle increases

extension

35

Away from body

abduction

36

Towards body

adductions

37

Rotation of joint toward middle of body

Internal rotation

38

Rotation of joint away from body

External rotation

39

Know movements for

Planes. see study guide

40

Shoulder blades together
" " Apart
Shoulder blades down
Shoulder blade up

Scapular retraction
protraction
depression
elevation

41

Alignment of muskoskeletal system that allows our center of gravity to be maintained over our base of support

Structural Efficiency

42

Influence applied by one object or another which results in acceleration or deceleration of the second object

Force

43

Groups of muscles that are recruited by the CNS to produce movement

Muscle synergies

44

Muscles that create trunk rotation

Internal and external obliques

45

Muscles that create upward rotation of scapula

Upper traps and lower part of serratus

46

Muscles that produce knee and hip extn during walking, running, stair climbing, etc

Glute max, quads and calf muscles

47

Muscles that work together to create plantar flexion

gastrocnemius, peroneus longus tibialis posterior

48

Muscles used to perform shoulder abduction

deltoid and rotator cuff

49

Nodding head is an example of what class lever

First, Fulcrum in middle

50

Push up of calf raise.. what lever

second. Fulcrum on one end, resistance in middle

51

Bicep curl is what kinds of lever

3rd class. Effort is in the middles

52

Motor response to external and internal behavior

Motor behavior

53

How the CNS system intergrates internal and external sensory info with previous experiences to produce a motor response

Motor control

54

Integration of motor control processes through practic and experience, leading to a relatively permanent change in the capacity to produce skilled movements

Motor learning

55

The change of motor skill behavior over time throughout the lifespan

Motor development

56

The cooperation of the nervous and muscular system in gathering and interpreting information and executing movement

Sensorimotor integration

57

Process whereby sensory info is used by the body to reacitvely monitor movement and the enviroment

Internal feedback

58

Use of sensory info and sensorimotor integration to help the human movement system in motor learning

Feedback

59

Info provided by external source

External feedback
