Two questions on COW ANATOMY
1. In the dentistry of a cow there is a wide gap on both the upper and lower jaw called the Diastema. I want to know what is it for?
2. In the dentistry of a cow the premolars and the molars on both jaws have flat ridged surfaces. I want to know why they have flat ridged surfaces?
Please give me as much detail as you can. Thank you XD

According to wikipedia
Diastema is a gap or space between two teeth. The term is most commonly applied to be an open space between the upper incisors (front teeth). It happens when there is an unequal relationship between the size of the teeth and the jaw. Many species of mammals have diastema as a normal feature, for example the gap between molars and incisors in rodents........

2. Cows have no top front teeth, just a tough pad of skin. Instead of biting at prairie grass and hay, cows use their long and flexible tongues that are course at the surface to wrap and pull the foliage in. They have nice bottom front teeth (eight) that secures the grass against the top pad, then will swing their heads up to break off the grass. They have six powerful molars (top and bottom of jaw) used for slight chewing the first time down, and for chewing the regurgitated cud on the rebound.

Diastema is sometimes caused or exacerbated by tongue thrusting or the pulling action of a labial frenulum (the tissue around the lip), which can push the teeth apart.
Unfortunately cows dont have teeth on the top jaw!

Dunno but I know 2:
They have flat ridged teeth because they don't need to catch and shear up meat. Instead they grind up grass all their life.
