muscular system Flashcards
what is the function of the bicep
flexion at the elbow
what is the function of the triceps
extension at the elbow
what is the function of the pectorals
adduction and flexion at the shoulder
what is the function of the hip flexors
flexion of the leg at the hip
what is the function of the gluteals
extension, rotation, and abduction of the leg at the hip
what is the function of the deltoid
flexion, extension, abduction and circumduction at the shoulder
what is the function of the latissimus dorsi
extension, adduction and rotation at the shoulder
what is the role of the tibialis anterior
dorsiflexion at the ankle
what is the role of the abdominals
flexion at the waist
what is the role of the rotator cuffs
rotation and abduction at the shoulder
what is the role of the gastrocnemius
plantarflexion at the ankle
what is the role of the quadriceps
extension at the knee
what is the role of the hamstrings
flexion at the knee
what is isometric contraction
the muscle stays at the same length
what is isotonic contraction
the changing of muscle length
what is concentric contraction
movement caused by the pulling on a bone causing the muscle to contract and shorten
what is eccentric contraction
helps to control speed of movement as the muscle contracts and lengthens
what are antagonistic pairs
pairs of muscles that work against eachother
what is the agonist
the muscle contracting
what is the antagonist
the muscle relaxing
what are the antagonistic pairs
quadricep and hamstring
bicep and triceps
hip flexor and gluteal
gastrocnemius and tibialis anterior
latissimus dorsi and mid deltoid
