Features of Cranial Norms: Frontalis, Verticalis, Occipitalis, Lateralis, and Basalis

Introduction

The human skull, a remarkable structure, comprises various distinct anatomical features, categorized into cranial norms. These include the frontalis, verticalis, occipitalis, lateralis, and basalis. Each norm provides essential insights into the functionality and structural composition of the skull.

Norma Frontalis: Anatomical Landmarks

Norma frontalis, or the frontal aspect of the skull, includes key landmarks:

• Glabella – A smooth, elevated area between the superciliary arches.
• Nasion – The point where the frontal bone meets the nasal bones.
• Supraorbital Margins – Form the superior boundary of the orbital cavities.

Foramina in Norma Frontalis

Several foramina enable the passage of neurovascular structures:

• Supraorbital Foramen – Allows the supraorbital nerve and vessels to pass.
• Infraorbital Foramen – Transmits the infraorbital nerve and vessels.

Clinical Significance

Understanding the cranial norms and their anatomical features aids in diagnosing traumatic injuries, surgical interventions, and neurological assessments.
