43
Q

the rotational movements from the joints

A

rotary motion

44
Q

What is sensorimotor integration?

Q

the cumulative sensory input to the CNS from all various mechanoreceptors that sense limb movement and body position.

A

proprioception

46
Q

What does proprioception training target and improve?

A

coordination, posture, and balance

47
Q

muscle controlled by the CNS to produce the same movements

A

synergistic muscles / muscle synergy

48

the maturation of muscle coordination

A

motor development

49
Q

the process of improving one’s motor skills with practice; results in lasting changes / one’s overall capability of responding

A

motor learning

50
Q

the process where people use cognition in order to coordinate the muscles and limbs of the body

A

motor control

51
Q

the overall study of motor development, learning, and control; one’s response to external and internal stimuli from the environment.

external feedback

53
Q

how one personally feels after they have practiced or performed a certain skill.

A

internal feedback

54
Q

biological system where the response of the output affects the initial input; sensory system gathers input from motor system in order to adapt/learn new motor skills.

A

feedback system

68
Q

Describe a Type I Lever…

A

the fulcrum sits directly between the energy moving the weight, and the weight itself.

69
Q

What are some examples of a Type I Lever?

A

scissors, seesaws, crowbars, a hammer extracting a nail…

70
Q

Describe a Type II Lever…

A

the fulcrum is at one end, the weight is in the middle, and the force is being applied on the opposite end.

71
Q

What are some examples of a Type II Lever?

A

wheelbarrows, can openers, staplers.

72
Q

Describe a Type III Lever…

A

the fulcrum is on one end, the weight is on the other, and the force(s) being applied are in the middle.
