Muscular System 2 Flashcards
(16 cards)
what are antagonistic muscles
pairs of muscles that work against each other where one contracts whilst the other one relaxes
what is the agonist
the prime mover is the muscle that’s contracting/shortening
what is the antagonist
the muscle that’s relaxing/lengthening
what is each muscle attached to
two bones by tendons where only one of the bones connected actually moves
what is the agonist/antagonist at flexion at the knee
the agonist is the hamstrings and the antagonist is the quadriceps
what is the agonist/antagonist at extension at the knee
the agonist is the quadriceps and the antagonist is the hamstrings
what is the agonist/antagonist at flexion at the elbow
the agonist is the biceps and the antagonist is the triceps
what is the agonist/antagonist at extension at the elbow
the agonist is the triceps and the antagonist is the biceps
what is the agonist/antagonist at flexion at the hip
the agonist is the hip flexors and the antagonist is the gluteals
what is the agonist/antagonist at extension at the hip
the agonist is the gluteals and the antagonist is the hip flexors
what is the agonist/antagonist at plantar flexion at the ankle
the agonist is the gastrocnemius and the antagonist is the tibialis anterior
what is the agonist/antagonist at dorsiflexion at the ankle
the agonist is the tibialis anterior and the antagonist is the gastrocnemius
what is the agonist/antagonist at flexion at the shoulder
the agonist is the front deltoid and the antagonist is the back deltoid
what is the agonist/antagonist at extension at the shoulder
the agonist is the back deltoid and the antagonist is the front deltoid
what is the agonist/antagonist at adduction at the shoulder
the agonist is the latissimus dorsi and the antagonist is the middle deltoid
what is the agonist/antagonist at abduction at the shoulder
the agonist is the middle deltoid and the antagonist is the latissimus dorsi
