Describe the role of the skeletal system in movement. - ANSWER - supports the soft tissue of the body
- protects crucial components of the body
- furnishes surfaces for the attachment of muscles, tendons, and ligaments
- provides storage areas for minerals and fats
-produces blood cells
Abduction - ANSWER - Movement away from the midline of the body
- occurs with the lateral movement of a body part away from the midline of the body
Adduction - ANSWER Movement toward the midline of the body
Circumduction - ANSWER - circular movement of a limb at the far end
- occurs when the distal part of the limb is moved to trace a circle while the proximal end of the bone
remains fixed.
Flexion - ANSWER - Decreases the angle of a joint
- state of being bent
extension - ANSWER increases the angle of a joint
Hyperextension - ANSWER the extreme or overextension of a limb or body part beyond its normal limit
Dorsiflexion - ANSWER - movement that bends the foot upward at the ankle
- backward bending of the hand or foot
,plantar flexion - ANSWER bends the foot downward at the ankle
Rotation - ANSWER CIRCULAR MOVEMENT AROUND AN AXIS
Internal Rotation - ANSWER Rotation of a joint toward the middle of the body.
External Rotation - ANSWER rotation of the hip or shoulder away from the midline
Supination - ANSWER face up
Pronation - ANSWER face down
Inversion - ANSWER turning inward
Eversion - ANSWER turning the sole of the foot outward
Isotonic Exercise - ANSWER involves contracting and relaxing your muscles through the full range of a
joint's motion
Isometric Exercise - ANSWER involves muscle contraction without shortening (there is no movement of
only a minimum shortening of muscle fibers)
isokenetic exercise - ANSWER muscle contraction with resistance
A nurse stretches out a patient's leg and moves it in a circle. This is an example of what type of body
movement?
A. Abduction
, B. Flexion
C. Circumduction
D. Dorsiflexion - ANSWER C. Circumduction
What are the factors that influence mobility? - ANSWER - developmental considerations
- physical health
- mental health
- lifestyle
- attitude and values
- fatigue and stress
- external factors
What benefits does exercise have on the cardiovascular system? - ANSWER - increased efficiency of the
heart
- decreased heart rate and blood pressure
- increased blood flow to all body parts
- improved venous return
- increased circulating fibrinolysin
Fibrinolysin - ANSWER substance that breaks up small clots
What benefits does exercise have on the respiratory system. - ANSWER - improved alveolar ventilation
- decreased work of breathing
- improved diaphragmatic excursion
What benefits does exercise have on the musculoskeletal system? - ANSWER - increased muscle
efficiency (strength) and flexibility
- increased coordination
- protects crucial components of the body
- furnishes surfaces for the attachment of muscles, tendons, and ligaments
- provides storage areas for minerals and fats
-produces blood cells
