Neuromuscular Flashcards
1
Q
Two basic nervous systems?
A
- Central Nervous System (Spine)
- Peripheral Nervous System (Extremities)
2
Q
Classification of muscles
A
- Skeletal (Attached to bone, bicep)
- Smooth (Intestines, stomach)
- Cardiac (Heart)
3
Q
Structure of a muscle
A
- Myofibril (Phosphagen energy)
- Sarcoplasm (Glycolyctic energy)
- Mitochondria (Oxidative energy)
4
Q
Characteristics of a muscle
A
- Excitability (Reaction to stimulus)
- Contractability (Shorter/Thicker)
- Extensibility (Longer/Thinner)
- Elasticity (Returning to original shape)
5
Q
Muscle actions
A
- Agonist (Primary movers)
- Antagonist (Opposes the Agonist)
- Synergist (Stabilises a joint around the movement)
- Fixator (Stabilses origin of Agonist)
- Stabilser (Stabilise the body during movements)
6
Q
Types of contraction
A
- Isotonic (Concentric/Eccentric)
- Isometric (Generates force not moving, constant length)
- Isokinetic ( Contracts and shortens at constant speed)
7
Q
What are the Range of Movement Phases
A
Inner
Middle
Outer
