What else can I help you with?
What is the muscle that helps move the arm over the head?
deltoid, pectoralis, trapz
Where is your deltoid on your body?
It is a triangular muscle covering the shoulder joint, it raises the arm from the side of the body
What would be the antagonist to the muscle that flexes the arm would be a muscle that?
Looks like you are looking for the antagonistic pair. The muscular group that flexes the arm would be the antagonistic pair of tricep brachi and the brachialis.
How do muscles work in pairs to bend and straighten the arm?
While one muscle contracts, the other muscle in the pair returns to its original length. The main muscle that bends your upper arm is called the Biceps brachii. The action is called flexion at the elbow. This muscle is on the "front" of the arm. The muscle that acts against this one is called the Triceps brachii. Its' action is extension at the elbow. This muscle is on the "back" of the arm. See the link below:
What is a muscle that rotates the upper arm?
There is not a single muscle that rotates the upper arm. The name of the muscle that contributes in rotation of the upper arm is deltoid muscle.
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.
Which two muscle work in opposite way to make the arm move?
forearm and upper arm muscles.
What is the purpose of the bone humerus?
The humerus bone is the one in your upper arm, and it is needed when you want to move your arm.
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 your left arm move when you move your right arm while walking?
it helps to keep your body balanced as you walk
How do muscles work in pairs to move a bone?
Well you have two muscles in your arm: the bicep and tricep. In order to make the arm move the two muscles must flex while the other extends and vice versa. So the bicep flexes and the tricep extends (the arm is bent). The bicep extends and the tricep flexes (the arm is straight)
What part of the body does the bicep move?
The biceps muscle is located in the front area of the upper arm. The biceps muscle helps to stabilize the large bone in the upper arm (the humerus) in the shoulder socket. It also helps to accelerate and decelerate the arm during overhead activities, like tennis or pitching. The biceps tendons keep the biceps muscle attached to the shoulder at one end and the elbow at the other end. Tendons are strong cord-like structures that connect each end of the biceps muscle to bones. At one end of the biceps muscle, tendons connect the biceps to the shoulder in two places. At the other end of the muscle, tendons connect the biceps muscle to the smaller bone (radius) in the lower arm. Source:AAOS
