Final answer:
The superior attachment for muscles involved in head and neck movements primarily includes the sternocleidomastoid, along with other muscles like the omohyoid and thyrohyoid. These muscles work together to flex, rotate, and stabilize the head by attaching to the vertebral column and hyoid bone.
Step-by-step explanation:
The superior attachment for the muscles that are responsible for moving the head and neck includes the sternocleidomastoid, which is the major muscle that laterally flexes and rotates the head. Additional muscles that contribute to this function include various infrahyoid muscles such as the omohyoid, sternohyoid, and thyrohyoid, which manage the position of the larynx and hyoid bone. For example, the thyrohyoid elevates the thyroid cartilage of the larynx, impacting vocal tone. The head is attached to the top of the vertebral column and is balanced, moved, and rotated by such neck muscles and others located in the posterior neck that primarily assist in head extension.
The neck muscles, as axial muscles, are grouped by location and function, often stabilizing or moving the head as necessary. This aligns with the broader functions of axial muscles, which also include movements of the trunk and performing respiratory functions, with some contributing to the stabilization of parts of the appendicular skeleton.
