Activity, Immobility, and Safe Movement Flashcards
Musculoskeletal System:
provides the framework for movement
Nervous System:
controls voluntary movement, posture, balance, and gait.
Cerebral Cortex:
regulates motor activity
Cerebellum:
controls coordination
Motor activity on the right side of the body is controlled by:
motor fibers on the left side of the brain. (vice-versa)
Neurotransmitters communicate electrical impulses from:
nerves-to-muscles facilitating movement
Proprioception:
awareness of posture and movement
Equilibrium:
balance that depends on the cerebellum and inner ear
Inner ear fluid remains stationary when the head moves quickly:
to allow a person to maintain balance
Body Alignment:
relationship of one body part to another
Body Balance:
achieved by low center of gravity; enhanced by posture
Friction:
force that occurs in a direction to oppose movement
Coordinated body movement:
result of weight, center of gravity, and balance
Lift Technique:
keep item close to your body
bend at knees
tightened ab muscles and tuck the pelvis
keep trunk erect and knees bent
Cardiopulmonary System:
provides oxygen and circulates nutrients to body tissues.
Damage to the cerebrum or cerebellum and spinal cord injury will impair:
a person’s ability to ambulate and control movement
Ischemia:
reduced blood flow
Hemiparesis:
weakness on one side of the body
Hemiplegia:
paralysis on one side of the body
Paraplegia:
lower body paralysis (caused by lower spinal cord trauma)
Flaccidity/Hypotonicity:
lack of muscle tone, results from lack of physical activity, injury, or neurological impairment
Spasticity/Hypertonicity
increases muscle tone, results from reduced ROM and abnormal movement patterns
Osteoporosis:
lack of bone mass
Osteoarthritis:
deterioration of joint cartilage
Quadriplegia:
inability to move all four extremities, also causes difficulty with breathing
Isotonic:
dynamic muscle contraction and active movement
Isometric:
static muscle contraction without joint movement
Isokinetic
muscle contraction against resistance
Aerobic:
activity amount of oz taken into the body is greater than that used to perform. uses larger muscle groups, improves cardiovascular conditioning.
Anaerobic:
muscle cannot draw enough oxygen from bloodstream
Atrophy:
wasting
Contracture:
permanent fixation of a joint
