The Muscular System Flashcards
There are two different types of muscles what are they
Voluntary and involuntary
What do voluntary muscles do
They are under your control and help the body move
Give an example of a involuntary muscle
Cardiac muscle which forms the heart
When exercising, what do voluntary muscles need
They need oxygen to move the body
The heart pumps blood and carries what and where to
Carries oxygen to the muscles
What the function of the biceps and give an example
Flexion at the elbow e.g. curling weights
What is the function of the triceps and give an example
Extension at the elbow e.g jump shot in netball
What is the function of the hamstrings and give an example
Flexion at the knee e.g bringing your foot back to kick a football
What is the function of the quadriceps
Extension at the knee e.g. performing a drop kick in rugby
What is the function of the pectorals major
Adduction and flexion of the shoulder e.g a forehand hit in tennis
What is the function of the gastrocnemius and give an example
Plantar flexion at the ankle e.g standing on your toes in ballet
What is the function of the hip flexors and give an example
Flexion of the leg at the hip e.g. lifting your knee when sprinting in running
What is the function of the deltoid and give an example
Flexion,extension,abduction or circumdation of the shoulder for e.g doing a front crawl in swing
What is the function of the tibalis anterior and give an example
Dorsi flexion at the ankle e.g. a heel side turn in snowboarding
What is the function of the latissimus dorsi and give an example
Extension,adduction or rotation at the shoulder e.g. during a butterfly stroke in swimming
What are antagonist muscles
Antagonistic muscles are pair of muscles that work against each other
What is the agonist
The agonist is the muscle that is contracting to produce movement
What is the antagonist
The antagonist is the muscle that is relaxing
When the knee-hamstrings & quadriceps shows flexion which is the agonist and the antagonist
Agonist-hamstrings
Antagonist- Quadriceps
When the knee-hamstrings & quadriceps shows extension which is the agonist and the antagonist
Agonist- quadriceps
Antagonist-hamstrings
In the elbow there’s the biceps and triceps when is shows flexion which one is the agonist and which is the antagonist
Agonist-Biceps
Antagonist-Triceps
In the elbow there’s the biceps and triceps when it shows to be extensions which one is the agonist and which is the antagonist
Agonist-Triceps
Antagonist-Biceps
All muscles are made of up of what
All muscles are made up of fibres
The muscle fibres can be what
Muscle fibres can be slow twitch or fast twitch
