Question

Jaw suspension of mammals

• A. Amphistylic
• B. Craniostylic
• C. Autostylic
• D. Hyostylic

Answer 1

The correct option is B Craniostylic

Jaw suspension means the fusion of upper jaw and lower jaw or skull for efficient biting. Craniostylic jaw suspension is mainly present in the mammals. It is a modification of autostylic suspension. The lower jaw is directly attached to the skull bone called squamosal. Meckel’s cartilage is changed into malleus so it is not available for jaw suspension.

So, the correct answer is option B.
