Description of 'parts' of a bit: cannons lie on top of the bars and are therefore the main pieces of the bit that go in the horse's mouth. They are measured by their diameter (thickness) not circumference (how far around).
The cheek is the length of the entire cheek piece.
The shank is the length from the cannon to where the rein attaches - snaffles don't have shanks.
The purchase is the length from the cannon to where the headstall attaches - it makes the headstall tighten up when the bit is used.
The link is the length of the middle part of the bit, if it's a 3 piece bit.

A basic Western Curb Bit has a gently ported mouthpiece and shanks to which the reins attach. As the rider takes a feel of the reins, more leverage is exerted on the horse's mouth and also on the poll (where the bridle goes over the head, behind the ears). By increasing the amount of port on the mouthpiece, pressure is applied to the roof of the mouth also. Since Western horses are ridden on a loose rein, the longer shank allows the rider to utilize the leverage by giving extremely light rein aids and attaining the same result as a rider using a snaffle on a firmer contact
