MSK-Essentials Flashcards
Body’s 3 sources of ATP
AKA Energy Systems
- ATP-PC (Phosphagen) System
- Anaerobic Glycolysis (Lactic Acid) System
- Aerobic (Oxygen) System
ATP-PC System
Think HIGH int, SHORT duration
- ATP prod during HIGH int, SHORT duration ex.
- Time= 15s
Ex. Sprinting 100m
Anaerobic Glycolysis System
Think HIGH int, SHORT duration, but longer vs ATP-PC
- ATP during HIGH int, SHORT duration acts
- Time= 30-40s
Ex. Sprinting 400 or 800m
Aerobic System
Think LOW int, LOOOONG duration
- ATP during LOW int, LOONG duration acts
- ATP production FAR greater, BUT reqs complicated series of chem rxns
Ex. Running a marathon
Motion occurs in 3 Cardinal Planes: Name them
Around 3 Axes: Name them
- Frontal, Sagittal, Transverse
- A-P (frontal), Med-Lat (sagittal), Vertical (transverse)
Common Jt Receptors?
(5)
- Free nerve endings
- Golgi lig endings
- Golgi-Mazzoni corpuscles
- Pacinian corpuscles
- Ruffini endings
LOOK THESE UP!!!
Golgi Tendon Organs
(GTOs)
Remember Tendons sensitive to Tension
- Encapsulated sensory receptors (in tendons) sensitive to TENSION
- esp when produced by active mm contracts****
- Transmit info about TENSION or RATE of CHANGE of tension w/in mm
Type I MM Fibers
*Endurance fibers
- Aerobic
- Red
- Tonic
- SLOW-Twitch
- SLOW-oxidative
endurance
Type II MM Fibers
2-Fast, POWER
- Anaerobic
- White
- Phasic
- FAST-Twitch
- FAST-Glycolytic
MM Spindles
IN MUSCLE BELLY….think LENGTH
- T/o belly of mm
- Send info to NS about MM LENGTH or RATE of CHANGE of length
UE
Shoulder Complex
Joints?
- GH
- SC
- AC
- Scapulothoracic (not true jt)
UE
Elbow Complex
Joints?
- Radiohumeral
- Ulnohumeral
- Proximal Radioulnar
LE consists of: (4)
Hip, Knee, Ankle/foot
Knee Jt
Tibiofem
Patellofem
Hip Jt
Synovial jt: head of femur + acetabulum
Ankle/Foot formed by:
Distal tibiofibular, talocrural, subtalar, midtarsal, forefoot
CS/TS/LS vertebrae
CS= 7
TS= 12
LS=5
UQS/LQS consists of: @min…
- posture
- ROM
- resistive testing (myos)
- reflexes
- dermatomes
Body composition: and ranges
- relative %of bw comprised of fat
- Men= 12-18%
- Women= 18-23%
Common methods to assess body comp:
- hydrostatic (GOLD STD.) (water)
- plethysmography (air)
- skinfold
- BMI (ht/wt)
- bioelectric imp.
LOOSE-packed pos of jt:
MIN stress on jt, MIN jt congruency, MIN lig laxity.
CLOSE-pack pos of jt:
MAX stress, FULL jt congruency, MAX lig tightness
