the agonist of the muscle is a motion that contracts the body to move in its opposition the antagonist is the muscle that causes movement of the posterior and anterior terms of the human body.
A somatic cell is any cell in the body or a plant and can therefore do anything, depending on where it is located. e.g. a muscle cell in an arm muscle contracts, an eye cell detects light etc. The only cells which are not somatic are the sex cells such as sperm, eggs (animals), pollen and ovum (plants).
Cilia and flagella help the cell to 'swim' in the body and move around. They're like tails or tentacles.
when it is cold the cremaster muscle contracts and draws the testes closer to the body to keep them warm.
Microfilaments
It contracts to move bones together.
muscle cells...
the function of a muscle cell is, by definition, to move. this can be accomplished when the cell contracts. contracting makes it denser, which is why when you feel a relaxed muscle in your arm suddenly tense up, it hardens.A muscle cell expands and contracts in order to allow the human body to control the movement of it's limbs.

A red blood cell takes about 20 seconds to move around your whole body
When one muscle of a pair contracts, the other muscle of the pair relaxes to allow movement of the body part.
When one muscle of a pair contracts, the other muscle of the pair relaxes to allow movement of the body part.
Axon.
transportation system
when you choose to move a pair of muscles work together, 1 contracts and 1 relaxes therefore making the body part move
