Q

Human Movement System (Part 1)

A

Movement is accomplished through the functional integrations of three systems - Nervous, Skeletal, and Muscular - These system work in concert to produce motion (kinetic) or human movement

53
Q

Human Movement System (Part 2)

A

All components of the human movement system must work together to produce sand movement; if one component is not working well is will affect the others and cause kinetic chain impairments. If one component of the kinetic chain is not working properly, it will affect the others and ultimately affect the the movement.

54
Q

The Nervous System (Part 1)

A

One of the main organ systems of the body and contains specialized cells that transmit and coordinate signals, providing a communication network within the body.

55
Q

The Nervous System (Part 2)

A

The nervous system is comprised of two main components 1) The Central Nervous System (CNS) is composed of the brain and spinal cord. 2) The Periperal Nervous System (PNS) is the nerves that communicate with the CNS.

56
Q

The Nervous System - Sensory Function

A

Is the ability of the nervous system to sense changes in either the internal or external environment

57
Q

The Nervous System - Integrative Function

A

Is the ability of the nervous system to analyze and interpret the sensory information to allow for proper decision making, producing the appropriate response

58
Q

The Nervous System - Motor Function

A

Is the neuromuscular response to the sensory information

59
Q

The Nervous System - Proprioception

A

Proprioception s the body’s ability to sense the relative position of adjacent parts of the body. Training the body’s proprioception abilities will improve balance, coordination, and posture. AND enable the body to adapt to its surroundings without consciously thinking about movement - thus it becomes important to train the nervous system efficiently to ensure proper movement patterns, which enhance performance and decreases the rick of injury.

60
Q

The Nervous System

A

Movement is a response to sensory informations and is therefore dictated by the nervous system. This reflects the importance of training in a multi sensory environment - the most effective way to create positive long-term results in clients is to directly affect (properly train) his or her nervous system.

61
Q

Central Nervous System (CNS)

A

Consists of the brain and the spinal cord

62
Q

Peripheral Nervous System

A

Functions: Provides a connection for the nervous system to activate bodily organs, such as muscles (Motor information). It relates information from bodily organs back to the brain, providing a constant update of the relation between the body and the environment (sensory information).

63
Q

Peripheral Nervous System (Part 2)

A

The PNS is subdivided into the Somatic and Autonomic nervous systems

64
Q

Somatic Nervous System

A

Consists of the nerves that serve the outer areas of the body and skeletal muscle, and is largely responsible for the voluntary control of movement

65
Q

Autonomic Nervous System

A

Supplies neural input to the involuntary systems of the body. It is further divided into the Sympathetic and Parasympathetic nervous systems.

66
Q

Muscle Spindle

A

Is a mechanoreceptor that is sensitive to changes in the muscular length and rate of length change

67
Q

Golgi Tendon Organ

A

Is a mechanoreceptor that is sensitive to changes in muscular tension and rate of tension change

68
Q

Joint Receptors

A

Is a mechanoreceptor that responds to pressure, acceleration and deceleration of the joint

69
Q

The Muscular System

A

Muscles generate internal tension which, under the control of the nervous system, manipulates the bones of out body to produce movement

70
Q

Connective Tissues

A

Are tendons that attach the muscles to the bone. They provide the anchor from which muscles can exert forces to control the bone and joint. - Poor vascularity (blood supply) and susceptible to slower repair and adaptation.

71
Q

Muscle Fibers

A

Contain typical cell components: Cellular plasma (sarcoplasm) - containing glycogen, fats, minerals, and oxygen-binding myoglobin, Nucleus, and Mitochondria: transforms energy from food into energy for the cell. Unlike typical cells, they have structures call myofibrils.

72
Q

Muscle Fiber Types - Type I

A

Type I - Slow Twitch: Higher capillaries, mitochondria, myoglobin, increased oxygen delivery, smaller in size, produce less force, slow to fatigue, and long-term contractions (stabilization)

73
Q

Muscle Fiber Types - Type II

A

Type II - Fast Twitch: Lower capillaries, mitochondria, and myoglobin, decreased oxygen delivery, larger in size, produce more force, quick to fatigue, and short-term contractions (force and power).

74
Q

Agonist

A

Muscle as Mover that acts as a prime mover (concentric) - Gluteus Maximus is an agonist for hip extension

75
Q

Synergist

A

Muscle as Mover that assists prime mover during movement (concentric) - The hamstrings and erector spine are synergistic with the gluteus maximus during hip extension

76
Q

Antagonist

A

Muscle as Mover that work opposite to the prime mover (eccentric) - The hip flexors resist the movement of hip extension

77
Q

Stabilizer

A

Muscle as Mover that support or stabilize the body while the prime movers and the synergists perform the movement patterns (isometric) - Transverse abdominis, internal oblique, and multifidus stabilize the LPHC during hip extension

78
Q

Isolated Function - Muscles as Movers

A

Is the primary movement it helps create when contracting concentrically (agonist, synergist) - the gastrocnemius concentrically accelerates plantarflexon

79
Q

Integrated Functions - Muscles as Movers

A

Are when is is contracting isometrically (stabilizer) or eccentrically (antagonist) - the gastrocnemius isometrically stabilizes the not and ankle complex AND the gastrocnemius eccentrically decelerated dorsiflexion. EX: the calf raise exercise takes the gastrocnemius through all of its isolated and integrated functions.

80
Q

The Skeletal System

A

Is the framework of stucture and movement. It is the resting ground for the muscles. Bones form junction that are connected by muscles and connective tissue known as joints.

81
Q

Divisions of the Skeletal System - Axial Skeleton

A

Skull, Rib Cage, and the Vertebral Column.

82
Q

Divisions of the Skeletal System - Appendicular Skeleton

A

Upper and Lower Extremities, Shoulder and Pelvic Girdles

83
Q

Joints

A

Provide the bones a means of being manipulated, allowing for movement throughout segments of the body. Provide stability, allowing for movement to take place without unwanted movement. All joints in the human body are linked together - movement of one joint will directly affect the motion of others.

84
Q

Reciprocal Inhibition

A

The simultaneous contractions of one muscle and the relaxation of its antagonist to allow movement to take place. The muscles on one side of a joint relax to allow the muscle on the other side to contract appropriately. Flexibility techniques rely on this principle to develop greater range of motion in joints.

85
Q

Length-Tension Relationships

A

The length at which a muscle can produce the greatest force. There is an optimal muscle length at which the actin and myosin filaments in the sarcomere have the greatest degree of overlap

86
Q

Length-Tension Relationships - Lengthening

A

Lengthening a muscle beyond this optimal length and then stimulating it reduces the amount of actin and myosin overlap, reducing force production.

87
Q

Length-Tension Relationships - Shortening

A

Shortening a muscles too much and then stimulating is places the actin and myosin in a state of maximal overlap and allows for no further movement to occur between the filaments, reducing its force output

88
Q

Force-Couple Relationships

A

A force-couple is a synergistic action of muscles to produce movement around a joint. Common Force-Couples: Internal and external obliques rotate the truck. Upper Trapezius and lower portions of the serrates anterior rotate the scapula upward, Gluteus Maximus, quadriceps, gastrocnemius, and soles produce hip, knee and ankle extension. Muscles working together for the productions of proper movement are said to be working in proper force-couple relationships.

89
Q

Motor Behavior

A

Is how the kinetic chain is able to create and learn movements. Consists of the study of motor control and motor learning.

90
Q

Motor Control

A

Is the study of movement. It is how the central nervous system integrates internal and external sensory information with previous experiences to produce a motor response
