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.
Muscles work in groups, working in opposition one with the other In the arm, groups of muscles work by contracting and relaxing to produce gross and fine movement, depending upon the task that the person wishes to carry out. For instance to bend and close the arm at the elbow, the flexor muscles (biceps) contract while the opposing triceps relax. And then to straighten the arm, the triceps (extensor muscles) will contract while the biceps relax. Rotator muscles work together to turn and twist the arm.
It uses a 'ball and socket' joint. So see how it works - make a fist with one hand. Cup your fist with your other hand - and slide it around the fist. The fist-hand is the top of the upper bone in your arm - and the other hand is the socket in your shoulder.
human arm moves with the joints. the human arm and joints are apart of the skeletal system the human arm is voluntaary which means it moves by itself you can control it. so when you need to move your arm all you pretty much have to do is think about moving your arm.

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.
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.
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.
What is the scientific meaning of cerebral palsy?
Cerebral palsy is a group of permanent movement disorders that appear in early childhood. It is caused by abnormal development or damage to the parts of the brain that control movement, balance, and posture. This condition affects muscle coordination and can result in problems with movement and posture.
What do muscles do for the body?
The main function of the muscular system is movement. Muscles are the only tissue in the body that has the ability to contract and therefore move the other parts of the body. Related to the function
Where is a action verb yes or no?
There isn't a specific location where action verbs exist. Action verbs are words that describe an action being performed by the subject of a sentence. They can be found in various parts of speech, such as verbs, adjectives, and adverbs, and are used to convey action or movement.
