Which muscle is the agonist and which is the antagonist?
The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist. One way to remember which muscle is the agonist – it's the one that's in 'agony' when you are doing the movement as it is the one that is doing all the work.
Which group of muscles is the antagonist to the abdominals?
Since the transversus abdominis, external oblique, and rectus abdominis flex your back, they are antagonists to your back extensor muscles. Only the above three abdominal muscles make up the antagonist group for your back extension. The only muscle that is left out is the internal abdominal oblique.
What are antagonistic pairs abdominals?
The opposing or antagonistic pairs include: Deltoids and Latissimus Dorsi in shoulder and upper back. Pectoralis Major and Trapezius in the chest and upper back. Abdominals and Erector Spinae in the stomach and lower back (core)

What is an example of an agonist and antagonist?
Buprenorphine is an example of a partial agonist. An antagonist is a drug that blocks opioids by attaching to the opioid receptors without activating them. Antagonists cause no opioid effect and block full agonist opioids. Examples are naltrexone and naloxone.

What muscle group is the antagonist of the obliques?
Bilaterally, the antagonists to the function of the obliques are the Trunk extensors, mainly the erector spinae. Unilaterally, the obiliques are opposed by the oblique muscle pair of the opposite side, contralateral (opposite) Transverse Abdominis, and the contralateral Quadratus Lumborum (QL).
Which muscle is a synergist to the rectus abdominis?
Synergist: Psoas major, Psoas minor, Diaphragm, Internal oblique abdominis, Transverse abdominis, Pyramidalis, Levator Ani.
What muscle is the antagonist to the transversus abdominis?
The transversus abdominis is the deepest ab muscle. It covers a large area, from the bottom of your sternum, down to the pelvis, and back to the sides of your hips. The rectus abdominis, external oblique, and transversus abdominis all flex the back, making them antagonists to the back extensor muscles.
What are examples of antagonistic pairs?
Muscles that work together like this are called antagonistic pairs. This type of action enables the body to move with stability and control. Examples of antagonistic pairs are: Biceps and triceps - at the elbow joint.
What's an antagonistic muscle pair?
One muscle of the pair contracts to move the body part, the other muscle in the pair then contracts to return the body part back to the original position. Muscles that work like this are called antagonistic pairs. In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens.
What muscles are agonist?
The agonist is typically the muscle that is the largest, most superficial muscle crossing the joint in motion, and is concentrically contracting or shortening the length of the muscle. An example of agonist muscle is the triceps brachii contracting during an elbow extension.
What are the agonist and antagonist muscles in the ankle?
Agonists: Gastrocnemius, Soleus. Antagonists: Tibialis Anterior.
What muscle is an agonist to the biceps muscle?
During a biceps curl, the synergists are the biceps brachii and brachioradialis, as the brachialis acts as the agonist.
What are antagonistic muscles explain with example?
Antagonistic muscles are those muscles which produce movements in an antagonistic pair of muscles by opposing the movement of the agonistic muscle . i.e. when one contacts the other relaxes and vice versa. Example- biceps and triceps, quadriceps and hamstrings.
Which abdominal muscles are antagonists to the back extensor?
The rectus abdominis, external oblique, and transversus abdominis all flex the back, making them antagonists to the back extensor muscles. Only those three abdominal muscles form the antagonist group for the back extension, leaving out the fourth abdominal muscle: the internal abdominal oblique. This muscle is sandwiched between ...
What is the job of the antagonist?
The job of the antagonist, the abdominals, is to slow down and stop the spine if it moves too fast or too far backward. It's important that you don't upset the balance between agonist and antagonist muscles by constantly working one side and leaving the other side alone.
What muscle is on the opposite side of the body?
On the opposite side of the body from the multifidus and erector spinae are the abdominal muscles. The most well-known ab muscle is the rectus abdominis, which is the muscle that you see when someone has a "six-pack.". This muscle runs from the bottom of the ribs down into the front of the pelvis. It acts to flex the spine, which is ...
Which muscle is used to flex the spine?
It acts to flex the spine, which is the opposite movement of the back extensor muscles. The rectus abdominis is not alone in its efforts to flex the spine. It also gets help from the external abdominal obliques and transversus abdominis.
Which muscles are used in back extensions?
The erector spinae and multifidus muscles are used in back extensions. Image Credit: jacoblund/iStock/Getty Images. It is a small miracle that the human body is so well coordinated that all of its roughly 650 muscles work in harmony to make you move. Each muscle group has an opposite muscle group that keeps it in check.
Why is it important to have two opposing muscles?
Having two opposing muscle groups is crucial because one can keep the other in check. In a back extension, the abdominals are keeping the lower and middle back muscles in check. If you perform a back extension as fast as possible without any weight your spine will move incredibly fast.
Where are the abdominal obliques?
The external abdominal obliques are the ab muscles on the sides of your torso. These muscles run from the bottom and sides of your ribs down into your pelvis. Advertisement. The transversus abdominis is the deepest ab muscle. It covers a large area, from the bottom of your sternum, down to the pelvis, and back to the sides of your hips.
