Which group of muscles below are antagonists?
The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist….Antagonistic muscle pairs.
| Biceps | Triceps |
|---|---|
| Hamstrings | Quadriceps |
| Gluteus maximus | Hip flexors |
| Gastrocnemius | Tibialis anterior |
| Pectoralis major | Latissimus dorsi |
What is the synergist of hamstring?
The gluteus maximus (GM) and hamstring muscles are synergists for hip extension. Hamstring tightness in individuals with low back pain could be a compensatory mechanism for weak gluteal muscles, as the hamstring and gluteal muscles have common attachments to the ischial tuberosity and sacrotuberous ligament5).
What are the muscles of the quadriceps group and the hamstrings group what are the antagonist actions of the quadriceps and the hamstrings?
The quadriceps femoris muscle group straightens the leg at the knee. The hamstrings are antagonists to the quadriceps femoris muscle group, which are used to flex the leg at the knee. The muscles located in the leg that move the ankle and foot are divided into anterior, posterior, and lateral compartments.
What are the four hamstring muscles?
The semitendinosus, semimembranosus, and biceps femoris muscles comprise the hamstring muscle group.
How quadriceps and hamstrings work together?
The quadriceps and hamstrings work together to move your leg. When you bend your leg, the hamstring muscles contract and the quads relax. Conversely, when you straighten your leg, the quads contract and the hamstring muscles relax.
What is the antagonist of the gluteus medius?
hip adductor muscles
The hip adductor muscles are the antagonists to the glutues medius. Hip abduction involves the contraction of the gluteus medius, causing a smooth lateral abduction of the lower extremity away from the body.
What is the antagonist of the masseter?
The temporalis is the antagonist of the masseter. The temporalis is the insertion of the masseter. The temporalis is the origin of the masseter. Correct answer: Since the temporalis assists in raising the jaw with the masseter, we say that the temporalis is the synergist of the masseter.
What muscle is an antagonist for leg flexion?
The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist….Antagonistic muscle pairs.
| Joint | Knee |
|---|---|
| Antagonistic pair | Hamstrings; quadriceps |
| Movements produced | Flexion; extension |
| Sport example | Jumping to block in volleyball; tuck jump in trampolining |
What are opposing muscle groups?
Opposing or antagonist muscles are the muscles that do the opposite of the muscle that is working. For example, when a person performs a bicep curl, the elbow flexes as the bicep shortens. The opposing muscle group in this case is the triceps, which lengthen or elongate in order to allow this movement at the elbow.
What is the antagonist muscle group for the pectoralis major?
The pectoralis major: agonistic: anterior deltoid, latissimus dorsi, teres minor, infraspinatus, pectoralis minor, serratus anterior. antagonistic: middle deltoid, lower trapezius, middle trapezius, posterior deltoid, levator scapulae, rhomboid major, rhomboid minor, supraspinatus, upper trapezius.
What is the agonist and antagonist?
An agonist is a drug that binds to the receptor, producing a similar response to the intended chemical and receptor. Whereas an antagonist is a drug that binds to the receptor either on the primary site, or on another site, which all together stops the receptor from producing a response.
