Verified step by step guidance

Understand that sutures are fibrous joints that connect the bones of the skull. They are immovable and allow for the growth of the skull during development.
Identify the bones of the skull that are typically connected by sutures. These include the frontal bone, parietal bones, occipital bone, temporal bones, sphenoid bone, and ethmoid bone.
Recognize that the mandible, or lower jawbone, is not connected to the skull by sutures. Instead, it is connected by a movable joint called the temporomandibular joint (TMJ).
Consider the other options: the vomer, nasal bone, and maxilla. These bones are part of the facial skeleton and are connected to other bones by sutures.
Conclude that the mandible is the only bone listed that is not connected to the skull by sutures, as it is connected by a movable joint.
