-
Ergonomics
- the science of fitting workplace conditions and job demands to the capabilities of the working population.
- goal- reducing injuries, strains, stress.
-
Myosin
- protein helps contract and relax muscles.
- (contractility and elasticity)
- actin- contractile protein.
-
-
Abduction
moves away from the midline. Outward away from the body.
-
Adduction
moves toward the midline. Inward toward the body.
-
Calcaneal
- (heel bone)
- tendon strongest and thickest of the body.
-
Tendon
- nonelastic, dense, fibrous connective tissue.
- muscle to bone.
-
-
achilles tendon
attaches the gastrocnemius muscle(muscle of the calf) to heel bone.
-
fascia
- a sheet of fibrous connective tissue that covers, supports, and separates muscle.
- flexable for movement but not elastic to accomodate swelling of enclosed tissues.
-
plantar fascia
thick band of tissue that covers the bones on bottom of foot.
-
heel spur
calcium deposit in the plantar fascia near its attachment to the calcaneus(heel) bone that can be one of the causes of plantar fascilitis.
-
diffrence between skeletal muscle tissue and smooth muscle tissue?
- muscle voluntary and external movement.
- smooth involuntary internal movement.
-
skeletal muscle tissue
- attaches to bones
- ROM
- striated (dark and light)
- voluntary (conscious control)
- biceps/triceps
-
smooth muscle tissue
- located internal walls of organs.
- moves and controls the flow of fluid thru internal organs.
- unstraited muscles.
- involuntary(ANS) muscles.
- digestive/unary system.
-
myocardial muscles
- aka myocardium
- forms the muscle wall of the heart.
- involuntary
- contracts/depolarization/systolic
- relaxation/repolarization/diastolic
-
pronation
turns the palm of the hand downward or backwards.
-
what is tennis elbow?
- inflammation of the tendons that joins the forarm muscles on the outside of the elbow.
- three joints: humerus, radius, ulna.
-
epicondylitis
- lateral:(tennis elbow) pain on the outside of forarm.
- medial:(golfer's elbow) pain on the palm side of forarm.
-
epicondyles
- cartilage bumps.
- outside, tendons around the elbow.
-
what causes tennis elbow?
- Overuse/alot of movement.
- Due to specific damage to forarm.
- The (ECRB)extensor carpi radialis brevis(brief) muscle helps stabilize the wrist when the elbow is straight.
-
who gets tennis elbow?
- most ppl who get tennis elbow are between 30-50.
- any one with risk factors.( racquet sports, improper stroke technique, improper equipment.
-
symptoms of tennis elbow
- pain or burning on the outer part of the elbow.
- weak grip strength.
-
EMG(electromyography)
- EMG diagnostic test that measures the electrical activity within muscle fibers in response to nerve stimulation.
- is used to rule out nerve compressions. Many nerves travel around the elbow, and the symptoms of the nerve compressions are similar to those of tennis elbow.
-
carpus
greek word karpos meaning wrist.
-
carpal tunnel syndrome(CTS)
- tendons that pass though the carpal tunnel are chronically overused and become inflamed and swollen.
- symptom: numbness and tingling in hand.(more at night)
-
paralysis(SCI)
- spinal cord injury
- loss of sensation and voluntary movements in a muscle thru disease or injury to its nerve supply.
- temporary/permanent
- cause: motor vehicles(36%) violence(28.9%) falls(21.2%)
-
-
RICE
- Rest
- Ice
- Compression
- Elevation
-
what part of hand/wrist is not effected by carpal tunnel?
all except pinky finger and ring finger because are innervated by a different nerve.
-
1st degree sprain/strain
- stretching of the tissue(a sprain in ligaments,or strain in tendons) without tearing of the fibers.
- characterized by pain and mild dysfunction of teh tissue or body part and minimal to no swelling.
-
# of named muscles?
600-640 named muscle
-
spinal cord length
17-18 inches long extends from base of brain down back to waist.
-
UMN'S
- Upper Motor Neurons
- nerves that lie w/i the spinal cord.
- function: to carry the messages back and forth from the brain to the spinal nerves along the spinal tract.
-
high C
- high cervical injury
- requires the individual use a power chair.
-
low C
- low cervical injury
- require manual chair.
-
Is there a cure for SCI?
- no
- swelling arround the spinal cord.
- 18 months of recovery.
-
peristalsis
is a series of wave like contractions of the smooth muscle in a single direction.
-
rocephin(GM)
- gluteus medius
- antibody that fights bacteria.
-
pneumococcal (VL)
- vaccine for an infection caused by a type of bacteria called Streptococcus pneumoniae
- vastus lateralis
-
-
VL
- vastus lateralis
- Ventral lateral nucleus, a component of the thalamus (neck ) in the central nervous system.
-
fasciopathy
fascia, fibrous band disease
-
terms
- tendon
- abduction
- electromyography
- supination
- varicella
- diaphragm
- epicondylitis
- naproxen
- paralysis
- quadriplegic
