Muscular System Flashcards
(28 cards)
How many muscles do you need to know for the gcse
14
What is a isotonic muscle contraction
A muscle contraction that results in movement
What is an isometric contraction
Muscle contraction but no movement occurs
What is an example of an isometric contraction
Plank
What is a concentric isotonic contraction
When the muscle shortens
What is an eccentric isotonic contraction
When the muscles lengthens
What is an example of a concentric contraction
The bicep shortening during a the upward phase of a bicep curl
What is an example of a eccentric contraction
Bicep lengthening during the downward phase of a bicep curl
When we bend the elbow the bicep contracts and the tricep relaxes. Which muscle is the agonist and antagonist
Agonist- bicep, antagonist- tricep
What muscles are found in the legs
Quadriceps, hamstrings, gastrocnemius, tibialis anterior, gluteals
What muscles are found in the torso
Deltoids, abdominals, pectorals, lattisimus dorsi, trapezius, rotator cuff
What muscles are found in the arms
Biceps, triceps
What is the function of the triceps
It creates extension at the elbow
What is the function of biceps
It creates flexion at the elbow
What is the function of hip flexors
It creates flexion at the hip
What is the function of the quadriceps
They create extension at the knees
What is the function of the tibialis anterior
It creates dorsi flexion at the ankle
What is the function of the gastrocnemius
Creates plantar flexion at the ankle
What is the function of the hamstrings
Creates flexion at the knees
What is the function of the gluteals
Creates extension at the hip
What is the function of the tricep
Creates extension at the elbow
What is the function of the rotator cuff
Rotation at the shoulder
What is the function of the deltoid
Allows adduction and abduction
What is the function of the pectorals
Adduction at the shoulder
