Summary Introduction

Introduction:

The muscles for facial expression are specific as they are not attached to the bones unlike the majority of the skeletal muscles. Their motion does not require movement of the bones. They arise from the surface of the skull and get presented into the skin. The muscles at the point of origin remain fixed, however, due to the movement of the skin these muscles develop facial expression.

Answer to Problem 1RQ

The correct answer is option (d) they insert into the skin.

Explanation of Solution

Explanation/justification for the correct answer:

Option (d) they insert into the skin. Facial muscles take part in facial expressions and movement. They are not same like other skeletal muscles that move with the assistance of skeleton. The movement of facial muscle takes place by pulling the skin, in the case no movement of bone takes place. The surface of the skull is the origin of the facial muscle.

The muscle fibers taking part in facial expression are administered into the dermis of the skin. With the movement of the skin, the muscles develop facial expression. So, the correct answer is option (d).

Explanation for the incorrect answer:

Option (a) they all originate from the scalp musculature. The muscles of facial expression do not originate from the scalp musculature. So, this is an incorrect option.

Option (b) they insert onto the cartilage found around the face. The given option is not relevant to the given question. So, this is an incorrect option.

Option (c) they only insert on the facial bones. The muscles involved in facial expression insert into the skin, not onto the facial bones. So, this is an incorrect option.

Conclusion

The muscles involved in facial expression get insert into the skin. Hence, the correct answer is option (d) they insert into the skin.
