I think that you are talking about what is called the A arms. They are usually part of the front suspension on a rear wheel drive, and can be in the rear, on a front wheel drive vehicle. They're function is to support the wheel spindle assembly, which is what the wheel bolts to. Each side has two, an upper, and a lower. They are usually on an ecentric, or use a shim type system to position the camber of the wheel, which is whether the top of the tire sticks out, or is pulled in. They also control the caster of the wheel, as well, which is the angle of the spindle, either forward, or back. These settings are a whole nother article to explain, but, basically, these settings determine if a car goes strait down the road, or not, and have a big influence on tire wear. The outsides are wearing that could be a camber issue, or a toe issue, or even a tire pressure issue. If your vehicle when you take your hands off off the wheel attempts to change lanes, or, perhaps, even area codes, this is an alignment issue, most likely.
A control arm is used in automotive suspension. The control arm is also known as the wishbone, A-arm or A-Frame. The control arm is used to attach the wheels of a car to the rest of the frame.
There are approximately 20 muscles in the human arm that control its movements, including muscles in the shoulder, upper arm, forearm, and hand.
You have no muscles in your fingers only tendons. The muscles in your lower arm control your hand movements and grip strength
The proximal limb muscles control functions and movements such as lifting, pushing, pulling, and stabilizing the body. These muscles are responsible for movements involving the shoulder, upper arm, and hip joints.
The neurons of the motor pathway control muscle movements by sending signals from the brain to the muscles. These signals coordinate and regulate voluntary movements such as walking, reaching, and grasping.
The biceps and triceps work together to create movements at the elbow joint. The biceps flex the arm, bringing the forearm closer to the upper arm, while the triceps extend the arm, straightening the elbow. This allows for movements like bending (flexion) and straightening (extension) of the arm.
A bionic arm works by using electronic sensors to detect muscle movements in the residual limb. These movements are then translated into signals that control the functions of the bionic arm, allowing the user to perform tasks such as grasping and lifting objects. Advanced bionic arms can also provide sensory feedback to the user, enhancing their ability to interact with their environment.
Medial rotation of arm muscles helps in bringing the arm closer to the body and rotating it inward. This movement is essential for activities like reaching, lifting, and throwing, allowing for a wider range of motion and better control of arm movements.

The rotator cuff muscles in the shoulder joint help to stabilize and rotate the arm bone (humerus) within the shoulder socket. They also assist in lifting and rotating the arm, as well as providing support and control during arm movements.
Its a rubber piece that holds the control arm to the frame of the vehicle it is round like the control arm to allow the arm to flex. (The control arm holds the wheel to the frame and uses the control arm bushing to flex over bumps while holding the wheel vertically and keeps your tires wearing properly).
