Flexion (same as bending) at the elbow joint (between the humerus and the radius and ulna) is mainly achieved by the Brachialis Muscle. This is not the answer most would expect as everyone knows the Biceps Brachii (Biceps of the arm) are what flexes this joint. In fact the biceps does both supination and flexion of the elbow because its insertion is on the radius. Only when the forearm is supinated, the biceps is able to assist the deeper and more powerful brachialis muscle with the flexion of the elbow.
Firstly, lets go through the movements at the elbow - There is flexion (bending forward at the elbow joint), extension of the elbow (opposite of flexion), pronation (rotation of the forearm to have the palm facing down when your hand is straight out in front of you) and supination (rotation of the forearm to have the palm facing upward).
Flexion of the elbow is caused by the primary flexors of the forearm - these are the biceps brachii, and the brachialis muscle. Interestingly enough the brachialis is just as important as the biceps brachii muscle in flexion, but often forgotten as it is deep to the biceps brachii.
Extension of the elbow is caused exclusively by the triceps brachii muscle.
However, for the bending of the elbow the movements are only flexion and extension - do not worry about pronation and supination when talking about bending of the elbow.
There are several muscles that bend(flex ) the elbow and they are Biceps Brachii, Brachialis, Brachioradialis, Pronator Teres, and Flexor Carpi Radialis.
An extensor muscle, in this case the tripceps brachii, reverses the flexion movement.

The brachialis is a muscle in the upper arm that flexes the elbow joint.
It flexes the arm at the elbow.
The joint between the humerus and the ulna bends the elbow.

That depends on the position of your elbow joint. Triceps is powerful extensor muscle of the elbow joint.
Yes, the word 'elbow' is both a noun (elbow, elbows) and a verb (elbow, elbows, elbowing, elbowed).The noun 'elbow' is a word for a type of joint, a word for a thing.
Thie brachialis is a muscle in the arm of the upper limb and it is the primary flexor of the elbow joint.
these muscle groups either extend a joint, extensors) or contract the joint (flexors). triceps extend the elbow joint, biceps bend the elbow joint.
None. The ulnar collateral ligament prevents abduction of the elbow joint.
