Question

Carnassial teeth are modified for:
a. Crushing
b. Tearing
c. Grinding
d. Cutting

Answer 1

Hint: Carnassials are the cheek teeth found in carnivorous animals. Their large and pointy appearance allows them to shear flesh and bone.The carnassials are sometimes shaped by the fourth higher bicuspid and also the initial lower molar, operating one against the opposite with a scissor-like action.

Complete answer:
a. Premolars - Premolars square measure used for tearing and crushing food. In contrast to your incisors and canines, premolars have a flat biting surface. We have got eight premolars in total. Molars - our molars square measure your largest teeth.

b. Carnassials are unit paired higher and lower teeth (either molars or premolars and molars)which area unit changed in such the simplest way to enable self-sharpening edges to surpass one another in an exceedingly cutting manner. And these kinds of teeth are employed for tearing instead of grinding it. They're found in animals of the Carnivora (e.g. tigers, wolves), during which they're the primary molars within the jaw and also the last premolars within the higher. Hence, sharp teeth area units changed for tearing.

c. The premolars, molars, and wisdom teeth are mostly used for chewing and grinding food.

d. Incisors at the sharp teeth at the front of the mouth that bite into food and cut it into smaller items. they're flat with a skinny edge. They're conjointly known as anterior teeth.

Hence option b is the correct answer.

Note:The central incisors and lateral incisors are mostly used for biting and cutting the food.
 These teeth are also referred to as sectorial teeth.Humans lack carnassial teeth.
