the hamstrings :)
Voluntary muscles can be flexed.
it is located on your neck and is flexed frequently
Liopsoas
The sternocleidomastoid muscles are the ones that flex when the intercostals are flexed. This will also cause the scalene muscles to flex.
An agonist muscle is a muscle that plays a part in the extension of a muscle. The agonist muscles for a knee extension are the quadriceps and hamstrings.
Well the limb will be Extended and the muscle will be elongated or in "extention", as opposed to a flexed or shortented muscle.
Biceps Biceps
It contracts, getting shorter and thicker.
It depends on your position and if you are moving with or against gravity. If you are standing up right in anatomical position, and elbow extension is occurring after elbow flexion, then it is eccentric. When the elbow is moving into extension from flexion, it is moving downwards with the force of gravity. In order for this motion to occur, the biceps brachii has to lengthen, and the triceps brachii has to relax. The biceps brachii therefore is your primary mover. If elbow extension were occurring against the force of gravity (imagine your shoulder is flexed to 180 and your elbow is flexed, and you want to move it into extension while your shoulder is still flexed at 180), then it would be a concentric contraction and your primary mover would be your triceps brachii as it would be shortening to complete the motion. The biceps brachii would be your antagonist and it would be relaxing to allow the triceps to do its work. concentric= muscle shortening eccentric= muscle lengthening I hope this helps. I'm an OT student and this has been drilled into me.
The Gluteus Maximus and the Wenus are known for being V shaped when flexed according to the National Health Care Advisory. Hope that helped you!
The over-extension of a muscle might feel like burning or pain in the muscle. After the exercise, the muscle can feel sore or even swollen.
That is incorrect! The hamstring group extend the thigh at the hip joint!
