Question at position 3 The muscle that can suck the cheeks in is the _____.ZygomaticusBuccinatorTemporalisMentalisMasseter

BlackTom AI · Accepted Answer

The question asks which muscle can suck the cheeks in. This is a classic anatomy detail.
Option 1: Zygomaticus — This muscle primarily elevates the upper lip and corners of the mouth (smiling), not involved in sucking the cheeks inward.
Option 2: Buccinator — Correct answer. The buccinator forms the muscular wall of the cheek and holds the cheek close to the teeth; it compresses the cheek, enabling actions like sucking and blowing.
Option 3: Temporalis — This muscle is a jaw elevator involved in chewing, not in retracting or sucking the cheeks inward.
Option 4: Mentalis — This muscle pouts the lower lip and raises the chin, not the cheek-inward action.
Option 5: Masseter — Another major jaw-elevating muscle essential for chewing, but it does not suck the cheeks inward.
In summary, among the listed muscles, the buccinator is the one specialized for compressing the cheek against the teeth, producing the sucking action.
