Updated on April 04, 2026
Muscle synergists We describe muscles that work together to create a movement as synergists. For example, iliacus, psoas major, and rectus femoris all can act to flex the hip joint.
What muscle is the antagonist for neck flexion?
Flexion 0-90 Antagonists: Upper Trapezius, Levator Scapula, Splenius Capitis, Splenius Cervicis.
Is the sternocleidomastoid and antagonist?
The sternocleidomastoid muscles help to flex the neck. Their antagonists are the longus capitis and the rectus capitis anterior.
Which group of muscles below are synergists?
1 – Prime Movers and Synergists: The biceps brachii flex the lower arm. The brachoradialis, in the forearm, and brachialis, located deep to the biceps in the upper arm, are both synergists that aid in this motion. A muscle with the opposite action of the prime mover is called an antagonist.
What muscle is the synergist for plantar flexion?
In an attempt to isolate the contribution of soleus to the resultant plantar flexion torque, activation of the synergist and antagonist muscles were minimised by: (1) flexing the knee of the test limb, thereby minimising the activation of gastrocnemius, and (2) applying an anaesthetic block to the common peroneal nerve …
Is the gracilis a synergist?
Synergist: Prime Movers: Iliopsoas, Pectineus, Tensor fasciae latae, Adductor brevis, Sartorius. Accessory Movers: Adductor longus and magnus (anterior part), Gracilis, Gluteus minimus.
What is the synergist muscle for Sternocleidomastoid?
scalenes
The scalenes are synergist muscles, or helper, muscles to the sternocleidomastoid. They assist the SCM in turning and tilting both the head and neck.
What is the antagonist muscle of the trapezius?
| Trapezius | |
|---|---|
| Actions | Rotation, retraction, elevation, and depression of scapula |
| Antagonist | serratus anterior muscle, Latissimus dorsi, Pectoralis Major |
| Identifiers | |
| Latin | Musculus trapezius |
What are synergists used for?
Synergists can counteract metabolic insecticide resistance by inhibiting detoxification enzymes or transporters. They are used in commercial formulations of insecticides, but are also frequently used in the elucidation of resistance mechanisms.
Is the brachialis a synergist?
The brachoradialis, in the forearm, and brachialis, located deep to the biceps in the upper arm, are both synergists that aid in this motion. A muscle with the opposite action of the prime mover is called an antagonist.
What are muscle synergists give an example?
Muscle synergists. We describe muscles that work together to create a movement as synergists. For example, iliacus, psoas major, and rectus femoris all can act to flex the hip joint. There are some sections within other muscles that can also assist with flexion of the hip joint, for example, the anterior fibers of gluteus minimus
What is the antagonist of a muscle?
We could also say that the antagonist is the main muscle that does the opposite of the action that it is resisting. For example, we could say that gluteus maximus is an antagonist of the primary hip flexor, iliopsoas because gluteus maximus is a hip extensor.
Is the gluteus maximus a synergist or antagonist?
Gluteus maximus is an antagonist of iliopsoas, which does hip flexion, because gluteus maximus, which does extension of the hip, resists or opposes hip flexion. We describe muscles that work together to create a movement as synergists. For example, iliacus, psoas major, and rectus femoris all can act to flex the hip joint.
