The galea aponeurotica serves as the tendon for which muscle?

The galea aponeurotica is a strong, fibrous sheet that acts as a tendon connecting different muscle groups in the scalp region. It functions as a primary attachment site for the occipitofrontalis muscle, which consists of two muscle bellies—one in the frontal region (frontalis) and the other in the occipital region (occipitalis).

This structure allows for coordinated movement between the front and back portions of the muscle, enabling actions such as raising the eyebrows or wrinkling the forehead. The occipitofrontalis muscle utilizes the galea aponeurotica for its movements, which is why this option correctly identifies the relationship between the muscle and the galea.

While the frontalis is part of the occipitofrontalis, the name specifically refers to the entire muscle including both front and back components. Other muscles like the temporalis and zygomaticus do not have the same direct association with the galea aponeurotica, making them less relevant to this question.
