since the bicep curl is a flexion of the forearm at the elbow, the biceps brachii and brachialis are mainly used, especially in the supinated position. a prone bicep curl uses brachialis and brachioradialis more. the biceps brachii function is much less, since it is also a forearm supinator, so it is deactivated in the prone position.
the triceps brachii are the antagonistic muscle group are not not involved in the bicep curl. the triceps extend the forearm at the elbow.

It is mostly Biceps brachii with little contribution from brachialis.

The bicep curl obviously helps the Bicep but it also helps you triceps as you pull your fist towards you your are contracting your bicept and relaxing your tricep
The preacher curl in my opinion is the best bicep exercise.It is better than barbell curl because barbell curl works bicep brachii but it does not give enough work to brachialis muscle.Preacher curl works both Bicep brachii and brachialis.First Mr.Olympia Larry "The legend"Scott used to do Preacher curl and he developed 20' inch Arm.

the bicep contracts in a concentric contraction which means the muscles has shortened. remember muscles can only pull they can not push. also the bicep curl can be described as elbow flexion and when the weight is lowered is called elbow extention. hope it helps
muscles work in pairs so when the bicep relaxes the tricep contracts, these actions create elbow extention (arm lowering) creating an objuce angle- lowering stage in a bicep curl
When you preform an arm curl, you use your bicep muscle. it all depends on how you curl. If you curl straight up or do a twisting motion while curling. You use your shoulder and bicep and maybe a small portion of the pectoral muscle where it meets the shoulder.
if you're speaking anatomically (as in origin and insertion), the origin of the bicep curl would be its fixed attachment at the supraglenoid tubercle and the coracoid process (two heads), as a bicep curl is an open chain motion (distal end is free moving --> proximal end is the origin). it would be more correct, though, to say refer to it as the origin of the biceps during a bicep curl.

hammer curl targets the bicep branchi and preacher curl targets the lower area of biceps..
Muscles cannot push, they can only pull which means they work in pairs in order to move, this is known as antagonistic pairs. For example with a bicep curl you have the agonist/ prime mover (Bicep) and the antagonist/ Opposing muscle group (Triceps). As the agonist contracts it pulls the antagonist which relaxes.
