Detailed explanation-1: -Incisor teeth are found in the rostral (front) portion of the mouth, but they are absent from the upper jaw. The premolars and molars (known as cheek teeth) are found in the caudal part of the mouth and are present in the upper (maxilla) and lower (mandible) jaws.
Detailed explanation-2: -Ruminants such as cattle, sheep and goats are herbivores with a unique digestive anatomy. A prominent feature of ruminant dental anatomy is that they lack upper incisors, having instead a “dental pad", as shown in the image to the right of a goat.
Detailed explanation-3: -In place of the top incisors, there is a hard leathery pad (known as the “dental pad”). In addition, cattle have a relatively immobile upper lip (compared to goats and sheep). Because of this unique oral anatomy, a cow uses its tongue to grasp a clump of grass and then bite it off.
