Muscle cells, specifically skeletal muscle fibers, contract to move the body. These cells work in coordination with the nervous system, responding to signals from motor neurons. When stimulated, they shorten and generate force, allowing for voluntary movements such as walking, running, and lifting. Additionally, smooth and cardiac muscle cells play roles in involuntary movements, such as the contraction of the heart and the digestive tract.
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.
Microfilaments
The lungs move downwards when the diaphragm contracts and flattens, allowing air to be drawn into the lungs.
It contracts to move bones together.
muscle cells...
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.
