Muscle cells can only contract,
thus pull is their only function.
Try it, its true. That's why most muscles come in pairs.
They are separated by the DIAPHRAGM - the thin, elastic muscle sheet that pulls downwards so that your lungs will pull air inwards.
Skeletal muscles
All pull-up variations will target the back muscles. It is an overall dominant back movement. The muscle group which will be worked hard are the lats and the traps. These are two of the larger muscle groups in the back. Almost all of the back muscles will assist in this movement. Also, your bicep and forearms will be involved and can be experienced as "sore" the day after doing pull-ups. The pull-up next to bent over rows and dead-lifts are considered to be a staple for back training.

The muscles can only pull, not push. So, to move a limb, one muscle relaxes while the other muscle pulls.
You can pull a muscle which means it really aches but you cant push a muscle
angle of pull is the angle between muscle insertion and the bone on which the muscle inserts
Muscle strain
Sorry, but your question makes no sense, and that is because it's not complete.you have to explain what you mean.---- If you mean " How to increase muscle " or something like that, then just do workout.PUSH UPS, PULL UPS. ( you don't really need weights ).
Any muscle can be pulled. However, it is unlikely that you will ever pull your vaginal muscle. A cold compress can be used to ease the pain.
It means like when you pull a muscle ! :)
pain
Yes.
Yes they can
No. Muscles only pull (contract) and relax.
They are separated by the DIAPHRAGM - the thin, elastic muscle sheet that pulls downwards so that your lungs will pull air inwards.
No muscle cells push, it just depends which muscle is doing the pulling. In a common joint, one muscle is used to pull the body part one way, and a different one is used to pull it back.
