Question

Quizplus · Accepted Answer

The longissimus muscle is a spinal extensor and helps in the extension of the trunk, neck, and head at the spinal joints. It does not contribute to rotation or flexion of these body parts. Additionally, the longissimus muscle does not extend the thigh at the hip joint, so option D is incorrect.
