Anatomy Flashcards
Tendon
Attach muscle to bone
Ligament
Attach bone to bone
GTO
Golgi Tendon Organ: senses force in muscle and causes contraction to slow down stretch
Muscle spindle
Senses length and speed of stretch, causes contraction and slows down stretch
How many bones in body
206
How many muscles in body
Over 700
Joint movement
- Flexion vs extension, 2. Abduction vs adduction, 3. Internal vs external rotation, 4. Lateral flexion (spine only), 5. Elevation vs depression (shoulder girdle only)
Lateral flexion
Spine and neck only. Side to side movements (side body stretches)
Spinal flexion
Rounded spinal erectors/back(cat, egg, child’s pose)
Spinal extension
Backbends (bridge, wheel)
Hyper-flexion of knees
Pigeon, garland, hero, child’s
Isometric muscle contraction
No movement. Just squeezing of muscle to bone.
Isotonic muscle contraction
Movement in joints.
Isotonic muscle movement:
- Concentric (squeezing, shortening, strengthing - agonist), 2. Eccentric (opening, stretching, lengthening - antagonist)
2 muscle fibers
- Red (slow twitch, O2 rich, aerobic exercise - slow steady endurance like marathon running /swimming). 2. White (fast twitch, ATP rich, explosive exercise - sprinting, jumping). 3. Intermediate (mix of both)
Energy systems for exercise: what we burn for fuel
- ATP (energy molecule found in muscle, white muscle fiber). 2. Glucose/Carbs (sugar in blood and liver, white and red muscle fibers, lactic acid (byproduct that causes the burn only during the first 20 min of exercise). 3. Fat/O2 (steady state breathing with stored body fat, CO2 (byproduct), red muscle fiber)
Anerobic exercise
Yoga, weight lifting, karate. Uses Glucose and Carbs- lactic acid in bloodstream gets exhaled. Red and white muscle fibers used.
Aerobic exercise
Running, cycling, rowing. Uses fat and O2. Red muscle fibers
Synergy
Balance between front and back muscles. Ex. Tricep vs bicep movement, quads vs hamstrings, abdominals vs spinal erectors
