Muscular COPY Flashcards
1
Q
Elastic connective tissue
A
mainly elastic fibers with a minor component of collagen fibers.
2
Q
Structure
A
- muscles are anchored by tendons
- muscular move bones
- skeletal bones moved at joint by muscle
- nervous impulses
- respiratory - o2 and co2 btwn air and blood
- circulatory - 02 to muscles remove co2
3
Q
Rheumatoid arthritis
A
A chronic inflammatory disorder affecting many joints, including those in the hands and feet.
4
Q
Arrangements
A
- antagonistic - opponents
- range of motion - mobility
- synergistic - same function work together
- tone- slight contraction
5
Q
Contraction
A
- isotonic exercise- bring about movement :jogging lifting weights
- isometric exercise -without movement
- muscle sense-brain knows abt muscle
- stretch receptors -detect changes
6
Q
Sarcolemma
A
- depolarization - contraction (action potential) makes inside positive and the outside negative
- polarization positive charge outside negative charge inside (resting potential)
- repolarization - impulse along ENTIRE sarcolemma ( action potential)
7
Q
Troponin and tropomyosin
A
prevent pulling of actin until sarcolemma depolarizes
8
Q
Tetanus and botulism
A
- tetanus -unable to relax (bacteria clostridium tetani)
- botulism-food poisoning ; diarrhea ,puking, hard to speak or swallow
9
Q
Dystrophy
A
- genetic disease w/ muscle tissue fixed by fibrous tissue
- Duchenne- sex linked trait (kids) X chromosome and recessive
10
Q
myasthenia gravis
A
autoimmune disorder extreme muscle fatigue
treatment = cholinesterase med
11
Q
movement
A
- flexion - decrease
- extension -increase
- adduction -(IN ) CLOSE to midline
- abduction-(out) AWAY
- pronation -down
- supination -palm up
12
Q
movement pt 2
A
- dorisflection elevate foot
- plantar flexion -point the toes
- inversion - medially to ankle
- eversion-lateral at ankle
- rotation -around longitudinal axis
13
Q
Intramuscular injections
A
- rapid absorption needed bc muscle has good blood supply .
- safest spot for injection - anterior gluteal site
