WARM UP 2/24Page 245/246 in book – WRITE THE definition given in this
warm up and then look up the answer
Abnormal contraction; different fibers contract at different times2. Contraction in which the tension stays the same, but muscle
shortens3. Contraction that is continual and partial; muscle tone4. Abnormal uncoordinated contraction of muscle groups5. Contraction in which length stays the same, but tension increases6. Quick, jerky contraction
NOTES Ch 8 3/15
Muscular system problems
ATROPHY
- muscle wastes away; shrinks
CAUSE: not being used
EX: bed rest, cast, injury
STRAIN
- Tear in a muscle
CAUSE: excessive use, pulled to hard
(swells due to blood from broken blood vessels)
HELP: place ice to stop swelling – constricts vessels
MUSCLE CRAMPS
• Sudden, involuntary muscle contractions
CAUSE: • Change in K and Na• From abnormal nerve activity,
dehydration, not stretching, exercising too long,
HELP: apply pressure with hands or stand on, heat compress, drink liquids (gatorade)
FASCICULATION (twitch)
• Abnormal nerve activity• Jump under skin
• From : stress, caffeine, decrease in sleep
TENDINITIS
• Inflammation of the tendons (attaching muscles to bones)
CAUSE
- injury, activity, exercising, repetitive movement
SHIN SPLINTS
Tendon under the tibia gets inflammed or torn away from bone
Causes pain when walking; sore
CAUSE: running on hard surfaces, walking long periods of time, jumping
HELP: ice, massage, taping ankle
TORN LIGAMENTS
ACL – in the knee; holding knee together
ROTATOR CUP – in shoulder; holding
HERNIA- organ protrude through a weak muscle
CAUSED: from increase in pressure in the body
a. Inguinal – groin area (common in males) (intestines through)
b. Abdominal (stomach through ab. muscle; intestines through stomach)
c. Hiatal – stomach pushes through diaphragm
Tetanus is the result of an infection that affects the muscles and nerves. It is usually due to a contaminated wound. Tetanus often begins with muscle spasms in the jaw (also called trismus or lockjaw), together with difficulty in swallowing, and stiffness or pain in muscles of the neck, shoulder, or back. Spasms soon spread to muscles of the abdomen, upper arms, and thighs.
TETANUS
TRICHINOSIS- infection in the muscles due to
worms
-diarrhea, weakness, muscle pain
CAUSE – eating undercooked pork – larvae multiply in body and grow in the muscle perimysium
1.5 million people/ year get
CycleCycle
- eat larva- eat larva
- mature in intestinal tract- mature in intestinal tract
- mate and produce eggs- mate and produce eggs
- go into muscle- go into muscle
- 1.5 million people get it a year- 1.5 million people get it a year
BOTULISM- prevents release of ACh- caused by bacteria- Improper canning or storage;
improper cooking
- Double vision, bright, blurred speech, inability to walk/stand, nausea, vomitting
- * big problem is respiratory
Botulism as a weapon Botulinum toxin was first developed as a biological weapon over 60 years ago; it can be aerosolised, or used to contaminate food,8
MUSCULAR DYSTROPHYGenetic disease; muscle cells
deteriorate
Many types!
Most common: DUCHENNE
- birth normal
- 2-6 yr muscle cells die; weak
- 9-11 yr cannot walk anymore
- 13-20 die
CONTORTIONIST
Extreme muscle flexibility (born with)
AGE and MUSCLES
- decrease muscle fibers- Decrease weight- Decrease strength (by 50% by age 80)
- Exercise helps kept muscle fibers strong
ASSIGNMENT:Read about STERIODS - what they are - what they are used for - side effects - what they do to women - what they do to men
ASSIGNMENT:You are a marketing coordinator and have been given the task of
making a brochure that for a high schools that will tell about physical therapy as a career. Read and make this brochure with at least 10 important facts in it. Front must be a cover page.
