muscles Flashcards
what’s the muscle pair to the triceps branchii
bicep branchii
what is the muscle pair to the quadriceps
hamstrings
what is the muscle pair to the forearm supinators
forearm pronators
what is the muscle pair to the gluteals
iliopsoas (hip flexors)
what is the muscle pair to the deltoids
latissimus dorsi
what is the muscle pair to the gastrocnemuis
tibialis anterior
what is the muscle pair to the pectoralis major
trapezius
what is the muscle pair to the erector spinae
abdominals
what is the muscle pair to the wrist flexors
wrist extensors
what is the muscle pair to the adductors
abductors
what is the agonist
the muscle contracting to produce the desired movement
what is the antagonist
the muscle paired with the agonist which relaxes the desired movement
what is the synergist
the muscle which also contracts to help the agonist produce the desired movement
what is the fixator
the muscle that stops any unwanted movement by stabilising nearby joints
what is concentric muscle contraction
muscle shortens under tension
e.g. up phase of a bicep curl
what is eccentric muscle contraction
muscle lengthening under tension
e.g. down phase of a bicep curl
what is isometric muscle contraction
muscle contracting but there is no change in length
e.g. plank or crucifix in gymnastics
what does your sternocleidomastoid do
elevation of the shoulder (shoulder flexion)
what does your brachioradialis do
pronation and flexion at the elbow
hyperextension at the wrists
what does your satoruis do
extension at the knee
what does the soleus do
plantarflexion
what does the rhomboid do
horizontal extension at the arm
retraction
