Which of the following parts of the cranium has no cranial nerves attached?

The correct answer is that the maxillary bone has no cranial nerves attached. The cranial nerves primarily emerge from the brain and are associated with the brainstem and certain regions of the cranial cavity. The maxillary region is part of the facial skeleton and is more involved with sensory functions, particularly through branches of the trigeminal nerve (V), rather than having direct cranial nerves associated with it.

In contrast, the other parts of the cranium, such as the occipital, temporal, and frontal bones, are associated with various cranial nerves that either emerge from the brain or branch out through these skull regions. For example, the occipital bone is associated with the spinal accessory nerve (XI), while the temporal bone is closely associated with parts of the vestibulocochlear nerve (VIII) and facial nerve (VII). The frontal bone also plays a role in housing and supporting structures related to other cranial nerves. These associations highlight the functional importance of the cranial bones in relation to the nervous system.
