Select an answer

Incisors are absent in upper jaw and their place is taken by dental pad in which animal?

  1. All Ruminants — Correct Answer
  2. Horse
  3. Camel
  4. Pig
Explanation:
Correct Answer: All Ruminants

In all ruminants (Cow, Buffalo, Sheep, Goat, Deer, Yak, Mithun, Giraffe, Nilgai etc.), incisors are absent from the upper jaw and their place is taken up by a "dental pad" (Table 33).

Dental Formula of Ruminants

2(I 0/4, C 0/0, PM 3/3, M 3/3) = 32 teeth. Note: I 0 in the upper jaw = no upper incisors.

Why Other Options Are Wrong
  • Horse: Has incisors in both jaws — dental formula 2(I 3/3, C 1/1, PM 3/3, M 3/3) = 40 teeth (stallion).
  • Camel: Has 1 upper incisor — dental formula 2(I 1/3, C 1/1, PM 3/2, M 3/3) = 34 teeth. Camel is a pseudo-ruminant, not a true ruminant.
  • Pig: Has incisors in both jaws — dental formula 2(I 3/3, C 1/1, PM 4/4, M 3/3) = 44 teeth.
