What is the difference between extension and flexion in terms of movement in the human body?
Extension and flexion are two opposite movements in the human body. Extension refers to straightening or increasing the angle of a joint, while flexion involves bending or decreasing the angle of a joint. For example, when you straighten your arm, you are extending it, and when you bend your arm, you are flexing it.

What is the joint that allows your arm to bend?

What is the name of the joint that allows your arm to bend?
The joint that allows your arm to bend is called the elbow joint. It is a hinge joint formed by the humerus (upper arm bone), radius, and ulna (forearm bones), enabling flexion and extension of the arm. This joint plays a crucial role in various arm movements and activities.

What bones allow you to bend your arm at the elbow?
The bones that allow you to bend your arm at the elbow are the humerus, radius, and ulna. The humerus is located in the upper arm, while the radius and ulna are the two long bones in the forearm. When the biceps brachii muscle contracts, it pulls on the radius, causing the elbow joint to flex and allowing you to bend your arm. The ulna acts as a stabilizing bone during this movement.
What happens when the elbow joint bends?
I doubt if you could actually bend it, However if it is damaged it will need to be replaced. if the actual insert into the bone is bent then it is a serious job getting the old part out cleaning up the site and then replacing it. the reliability of the insert is not as good afterwards either.

What is a muscle that causes a joint to bend when it contract?
A muscle that causes a joint to bend when it contracts is called a flexor. Flexor muscles, such as the biceps brachii in the upper arm, work by shortening and pulling on the bones to decrease the angle at a joint, facilitating movements like bending the elbow. In contrast, extensors are muscles that increase the angle at a joint.
