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.

∙ 14y agoMuscles 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.

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 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

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.
What is muscle boundness?
This refers to overdeveloped muscles. It can be a direct result of adding muscle mass in short period of time without any stretching or high endurance training. The most common parts of the body affected by muscle boundness include chest, back and traps.
What does skeleton movement mean in a clock?
It refers to the movement of the inner workings of the clock; when movement of the inner parts of the clock or "skeleton" parts are visible.
What is meaning of tremors?
Tremors are involuntary muscle contractions and relaxations that lead to the movement of several body parts. A common example of tremors is the chattering of teeth in response to fear or cold temperatures.
What are the major parts of skeletal muscle fiber?
It is put here short and sweet. 1. Marrow 2. Calcified Bone 3. Periosteum 4. Spongy Bone 5. Cartilage TENDONS attach the MUSCLE to the BONE.Like the stringy thing in a chicken
