The muscular system Flashcards
What are two muscles in your arm
Bicep,tricep
What muscles are found in the core/centre
Abdominals
What is the primary function of the muscular system?
The primary function of the muscular system is to facilitate movement of the body.
Name the muscle at the top part of your leg above your knee
Quadriceps
Name the muscle at the top of your shoulder
Deltoid
Which type of muscle is responsible for pumping blood in the heart?
Cardiac muscle is responsible for pumping blood in the heart.
What is the role of tendons in the muscular system?
Tendons connect muscles to bones, allowing for movement.
What are the muscles found in your upper leg?
Hamstring,Quadriceps
What is the name of the muscle found in your neck that helps with inhalation during exercise
Sternocleidomastoid
What do muscles work in to create/allow movement
Antagonistic pairs
What is an agonist/prime mover
The muscles that contracts to cause movement
What is an antagonist
The muscle that relaxes to allow the agonist to contract
What muscle is the main agonist in flexion at the elbow joint
Biceps
What muscle is responsible for plantar flexion at the ankle joint
Gastrocnemius
What muscle is responsible for dorsiflexion at the ankle joint
Tibialis anterior
What muscle is the maon agonist causing extension at the knee
Quadriceps
What movement are the hamstrings responsible for at the knee
Flexion
What movement are the triceps responsible for at the elbow
Extension
What is an Isotonic muscle contraction
when the muscle changes length as it contracts and causes movement
Name Two different types of Isotonic contraction
Concentric and eccentric
Define a concentric contraction
isotonic contraction where the muscle shortens as it contracts
Define an eccentric contraction
isotonic contraction where the muscle lengthens as it contracts - usually involves controlling/slowing down a downward movement
Give an example of an eccentric contraction
Downward phase of a press up
Downward phase of a bicep curl
Downward phase of a squat or jump
Define an Isometric contraction
where the muscle remains the same length when contracting (under tension), no movement
Give a sporting example of an Isometric contraction
Plank, rugby scrum, handstand
