The arm is made up of two main muscles (biceps & triceps) for the arm to move one of these muscles must contract and the other must relax. Which muscle does which depends on which way you are moving your arm.
Additional answer
This does not mention the muscles in the forearm, which mainly move the hand, or the muscle in the shoulder, deltoid, which lifts the arm.
What else can I help you with?
How does muscle action result in movement of body parts?
Muscles are attached to bones.
What type of tissue is the skeletal muscle?
Skeletal muscle is a striated muscle used to control movement of specific body parts
Will a muscle contraction will always promote movement of body parts regardless of how they are attached?
No
What are the common parts of muscular system?
The common parts of the muscular system are the fibers, which are striated, the cardiac muscle, smooth muscle and skeletal muscle. There are also flexor muscles and extensors muscles, which aid in movement.
What is the name for muscles that work as opposite pairs to move bones?
The muscles that work as opposite pairs to move bones are called "antagonistic muscles." When one muscle in the pair contracts to create movement, the other muscle relaxes to allow that movement to occur. This coordinated action helps in the smooth and controlled movement of limbs and other body parts. An example of this is the biceps and triceps in the arm.
Is the antagonist muscle one that has an action directly opposite to that of the agonist?
Yes. An antagonistic pair of muscles, such as the biceps and the triceps, allows movement of body parts through opposing motions. As one of these muscles contracts, the other relaxes.
What is a group of muscle cells called?
Muscle cells grouped together are called muscle tissue. The muscle cells contract and elongate to make the movement in the body parts. Muscle cells are found in several specialized forms such as Cardiac, skeletal or smooth muscles etc.Muscle cells grouped together are called muscle tissue.

What type of muscle tissue is responsible for moving most parts of the body?
skeletal
What is This type of tissue that makes parts of the body move by contracting or shortening?
Muscle tissue is the type of tissue that makes parts of the body move by contracting or shortening. It is composed of muscle fibers that have the ability to generate force and produce movement.
Which muscle trait is the ability to shorten and produce movement when stimulated?
The muscle trait that refers to the ability to shorten and produce movement when stimulated is called "contractility." This characteristic allows muscle fibers to contract in response to neural stimulation, generating force and enabling movement of body parts. Contractility is essential for all types of muscle movements, including voluntary actions like walking and involuntary actions like heartbeat.
Do the muscle pull the structure or push them explain briefly?
Muscles generally pull on structures rather than push them. When a muscle contracts, it shortens, creating tension and pulling on the attached structures such as bones or other tissues. This pulling action allows for movement and manipulation of body parts.
Does skeletal muscle have T-tubules and what is their function in muscle contraction?
Yes, skeletal muscle has T-tubules, which are invaginations of the cell membrane that allow for the rapid transmission of action potentials deep into the muscle fiber. This helps to coordinate the contraction of muscle fibers by ensuring that all parts of the muscle fiber receive the signal to contract simultaneously.
