Anatomy + Physiology Flashcards
What is the agonist in the bicep curl
Bicep Brachii
What is the agonist in a tricep push down
Triceps brachii
What plane does Flextion and extention occur on
Sagital plane
What plane does rotation occur on
Transverse
What plane does abduction and adduction occur on
Frontal
What is eccentric contraction
Where the muscle lengths to keep tension and control the movement
What is concentric contraction
Where the muscle shortens to produce effort
What is isometric concentric
Where the muscle produces effort but there is no movement
What is the agonist and antagonist in hip Flextion
Illiopsis - agonist
Gluteus maximus - antagonist
What is the agonist and antagonist in abduction at the hip
Agonist - glueteus minimus
Antagonist - adductor longus
What is the agonist and antagonist in leg extension
Rectus femorus - agonist
Biceps femorus - antagonist
What type of joint is the ankle
Hinge
What are the articulating bones at the ankle
Talus
Tibia
Fibia
What type of joint is the spine
Cartilaginous
What type of joint is the wrist
condyloid
What is a fixator muscle
A muscke which helps the agonist work effectively
What is a synergistic
A muscle that helps apply effort
Describe type 1 muscle fibres
Slow
Aerobic
Describe 2a muscle fibres
High force production
Prolonged high intensity 10s - 3mins
Fast Oxidative Glycolytic ( FOG )
Describe type 2b muscle fibres
Fast glycolytic
Very high force production
Very low resistance to fatigue
Name two muscles at the rotator cuff
Teres major
Subscapularis
What is the agonist and antagonist in adduction at the shoulder
Lattimus Dorsi - agonist
Deltoid - antagonist
How might a warm up affect the skeletal muscle tissue of the golfer
Increase blood flow
Increasing muscular elasticity
Reducing risk of injury
What is the agonist in election of the spine
Agonist - erector spinae
Agonist - rectus abodimus
Define blood pressure
The force of blood against arteries
What is angular motion
is movement of a part of a body part in a circular path about an axis of rotation.
Explain how a motor unit transfers a neural impulse into muscular contraction
Dendrites receive electrical impulses
Axon transmits action potential towards muscle fibre
At neuromuscular junction acetylcholine flows into the synaptic cleft to help impulse pass from motor neurone into muscle fibre
If impulse is big enough muscle fibres will contract
What is isotonic contraction
Where the muscle changes in length while tension increases the mains constant
What is isotonic contraction
Where the muscle changes in length while tension increases the mains constant
