Verified step by step guidance
1
Understand the anatomical location of the posterior aspect of the skull. The posterior aspect refers to the back side of the skull.
Identify the ligamentum nuchae. It is a ligament that extends from the external occipital protuberance at the base of the skull to the spinous processes of the cervical vertebrae, providing support for the head and neck.
Review the bony features listed in the options: Coronoid process, Zygomatic arch, Mastoid process, and External occipital protuberance. Determine which one is located on the posterior aspect of the skull.
Coronoid process is part of the mandible (jawbone) and is not located on the skull's posterior aspect. Zygomatic arch is part of the cheekbone and is located laterally, not posteriorly. Mastoid process is part of the temporal bone and is located inferiorly and laterally, not directly posterior.
The external occipital protuberance is a prominent bony feature located on the posterior aspect of the skull. It serves as the attachment point for the ligamentum nuchae, making it the correct answer.
