- Skeletal and Muscular Systems
- Joints, movements and muscles
- Shoulder
- Delts, lats, pecs, traps
- Elbow
- Bicep brachii, tricep brachii
- Wrist
- Wrist flexor, wrist extensors
- Hip
- Iliopsoas, glutes, adductor longus
- Knee
- Bicep femoris, rectus femoris
- Ankle
- Tibialis anterior, soleus, gastrocnemius
- flexion (dorsi, plantar), extension, abduction, adduction, rotation, circumduction
- Shoulder
- Planes of movement
- Frontal
- Divides into front and back - creates sideways motion
- Transverse
- Divides into upper and lower, creates rotational motion
- Sagittal
- Divides into left and right, creates forward/backward motion
- Frontal
- Antagonistic pairs
- Agonist
- Contracts to create movement
- Antagonist
- Opposes the movement
- Fixator
- Stabilizes the joint
- Agonist
- Contractions
- Isotonic
- Concentric
- Muscle becomes shorter to create movement
- Eccentric
- Muscle lengthens when creating movement
- Concentric
- Isometric
- No change in muscular length - muscles contract to maintain stability
- Isotonic
- Motor Unit
- 4. Creates muscular contraction
- 3. Neurotransmitter carries impulse across synaptic cleft to motor end plate
- 2. Action potential carried to neuromuscular junction
- 1. Motor neuron creates action potential
- 2. Action potential carried to neuromuscular junction
- 3. Neurotransmitter carries impulse across synaptic cleft to motor end plate
- All or None Law
- Muscle will either fully contract or not at all - no inbetween
- 4. Creates muscular contraction
- Fibre Types
- Slow Oxidative
- Contract slow Aerobic Resist high fatigue Force low Oxidative capacity high Glycogen low Capillary high
- Fast Glycolytic
- Contract fast Anaerobic Resist low fatigue Force high Oxidative capacity low Glycogen high Capillary low
- Fast Oxidative Glycolytic
- Contract fast Anaerobic Resist medium fatigue Force high Oxidative capacity medium Glycogen medium Capillary medium
- Slow Oxidative
- Joints, movements and muscles
