Your sliding joint allows your spine to bending or stretching
at the elbow. "Flexion of the arm" just means to bend it.
The scapula and the upper arm bone meet at the glenohumeral joint, also known as the shoulder joint. This joint allows for a wide range of motion, including flexion, extension, abduction, adduction, internal rotation, and external rotation of the arm.
The contraction of a flexor allows the arm or leg to bend
Ball-and-Socket, the shoulder's cartilage being the socket and the arm's ending being the ball.
The elbow joint allows you to bend your arm. This joint is formed by the connection of the humerus bone (upper arm) with the ulna and radius bones (forearm). It enables flexion and extension movements of the arm.
Your sliding joint allows your spine to bending or stretching
Your shoulder joint allows you to raise your arm above your head.
hinged.......
The ball-and-socket joint of the shoulder allows the upper arm to be raised and lowered.
An elbow is a joint that helps you bend your arm.
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.
ball and socket joint
The elbow joint is a hinge joint, allowing movement in one plane (flexion and extension). It is comprised of the humerus bone of the upper arm, and the ulna and radius bones of the forearm. The motion at the elbow joint allows the wing to bend and straighten.
the ball-and-socket joint
The muscular system provides the force needed to bend the arm by contracting the biceps muscle, while the skeletal system, specifically the elbow joint, allows for the bending motion to occur by providing a point of movement.
a joint called the hinge joint allows you to bend and straighten your knees!!:)
