We describe a method for repeatedly visualizing murine microglia and circulating monocytes in vivo over hours, days or weeks using transcranial two-photon microscopy. We demonstrate how to prepare a thinned-skull window that allows intermittent observation of quiescent microglia that can be activated by adjacent stereotactic injection of the HIV-1 regulatory protein Tat.

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures. Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Overview of the Skull

The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws. The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
FAQs
The cranium provides the framework associated with protection of the brain, whereas the facial skeleton forms the structural basis of the face. Studying them as related but distinct regions helps organize observations of head development, interpret anatomical relationships, and distinguish changes affecting the braincase from those involving facial structures during analysis.
These different connections reflect different functional requirements. Fibrous sutures hold the skull bones together as a stable framework, while the jaw’s movable joint permits chewing. Comparing the two helps explain how skull anatomy combines structural protection with controlled movement, and it gives learners a clear way to distinguish cranial connections from jaw articulation.
Foramina are important anatomical landmarks because they provide routes through the skull for cranial nerves and blood vessels. Their positions and relationships connect skeletal structure with neuroanatomy. Recognizing these openings therefore helps students interpret how the skull relates to neural and vascular pathways and supports more informed reading of anatomical images.
A useful examination separates the cranium from the facial skeleton, then records relationships among bones, sutures, foramina, and the movable jaw joint. This structured approach supports identification of major regions and openings, improves interpretation of radiographs, and helps compare anatomical observations across specimens without treating the skull as an undifferentiated structure.
Skull anatomy provides an anatomical reference for relating visible features in radiographs to specific regions, connections, and openings. That framework supports assessment of injury and disease by helping observers organize structural findings and recognize their location. Accurate regional interpretation is especially important when examining relationships involving the cranium, facial skeleton, and jaw.
In anthropology, skull anatomy supports identification of specimens and assessment of biological variation. In biology, the relationships among skull regions contribute to the study of head development and structural diversity. These applications show how careful comparison of skeletal features can provide information beyond basic identification, linking anatomy with developmental and population-level questions.
Knowledge of skull regions and their relationships supplies the anatomical context needed for planning dental or neurosurgical procedures. Clinicians can use the arrangement of the facial skeleton, cranium, jaw joint, and foramina to interpret relevant structures before intervention. This reduces reliance on isolated landmarks and supports planning based on the organization of the head as a whole.
