The other relaxes. This other is called the antagonist. The one contracting is called the agonist.
What else can I help you with?
how does one muscle in a pair behave when the other muscle contract?
When one muscle in a pair contracts the other expands.
As one muscle in a pair relaxes what does the otyher muscle do?
contract
Are striated under skeletal muscle?
Because muscle cells can only contract, not extend, skeletal muscles most work in pairs. While one muscle contracts, the other muscle in the pair relaxes to its original length.
How your arm uses muscles to move?
Your arm uses its bicep and tricep muscle to move. Muscles can only contract so they have to work in pairs. Ex. Bicep and tricep One muscle contract, the other relaxes
Why do muscles shorten when they contract?
Muscles shorten when they contract because the muscle fibers within the muscle bundle slide past each other, causing the muscle to contract and pull on the attached bones, resulting in movement.
What does a muscle cell do that no other cells can do?
Muscle cells have unique structures called sarcomeres that allow them to contract and generate force, enabling movement. No other cells in the body have the ability to contract in the same way as muscle cells.
What word starts with R and means the opposite of contract?
The word "contract" is referring to a muscle doing work, and the opposite is relax. Skeletal muscles work in pairs, and often one of the pair will contract while the other relaxes.
The only tissue that is able to contract and shorten in the body?
muscles
What is the tissue that makes up organs that are able to contract or shorten?
The tissue that makes up organs that are able to contract or shorten is known as muscle tissue. Muscle tissue is composed of muscle cells that contain protein filaments that slide past each other, causing the muscle to contract and generate force. There are three types of muscle tissue: skeletal, cardiac, and smooth.
What is needed for living muscle to contract?
A living muscle needs oxygen in the blood and muscle elasticity to contract and move.
What kind of muscle cell contract?
Smooth muscle cells contract in response to fluid flow.
What type of muscle tissue has a gap junction?
Cardiac muscle tissue has gap junctions to allow impulses to travel quickly though the tissue so the two atria can contract as one and the two ventricles can contract as one.
