Muscle tissue is responsible for helping animals move. It contracts and relaxes to generate force and movement in response to nerve signals. There are three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle, each serving different functions in the 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.
The lungs move downwards when the diaphragm contracts and flattens, allowing air to be drawn into the lungs.
Microfilaments
It contracts to move bones together.

cause the body to move.
cause the body to move.
the function of a muscle cell is, by definition, to move. this an 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 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
An example of an internal force is the tension created within a muscle when it contracts to move a body part.
