Final answer:
The deepest muscles in the posterior view include muscles such as the inferior gemellus and obturator internus in the hip/thigh region, and the infraspinatus in the shoulder region. These muscles are key for movements such as lateral rotation of the femur and arm.
Step-by-step explanation:
The deepest muscles in the posterior view, according to medical illustrations such as those by Häggström (2014), can vary depending on the specific region of the body being examined. For example, in the posterior view of the neck, the deep muscles are responsible for moving the head, cervical vertebrae, and scapulas. When discussing the posterior abdominal muscles, it is noted that the transversus abdominis forms the deepest layer. In the region of the hip and thigh, the inferior gemellus muscle and the obturator internus muscle are deep to the gluteus maximus and are involved in lateral rotation of the femur at the hip. The infraspinatus muscle, which helps in laterally rotating the arm, is also considered one of the deeper muscles in the posterior view. It is important for students to understand the layering of these muscles and their functions to have a comprehensive view of the human muscular system.
