Introduction
Greetings, readers! Welcome to our in-depth exploration of the skull’s anterior view, showcasing its intricate structure and offering a labeled guide for easy understanding. Throughout this article, we’ll delve into the various bones, sutures, foramina, and other anatomical features visible in the skull’s anterior aspect.
The Frontal Bone
The frontal bone forms the forehead and the roof of the orbits. It consists of the following parts:
Supraorbital Margin
The supraorbital margin is the superior border of the orbits, housing the eyebrows.
Glabella
The glabella is a smooth area between the supraorbital margins, located above the bridge of the nose.
The Nasal Bones
The nasal bones form the bridge of the nose and articulate with each other at the nasal suture. They are small and paired, contributing to the nasal cavity’s shape.
The Maxilla
The maxilla, also known as the upper jawbone, consists of the following subparts:
Canine Fossa
The canine fossa is a depression located lateral to the incisive foramen, housing the canine teeth.
Infraorbital Foramen
The infraorbital foramen is an opening located below the orbit, transmitting the infraorbital nerve and vessels.
The Zygomatic Bone
The zygomatic bone, commonly known as the cheekbone, forms the prominence of the cheek and has the following subparts:
Temporal Process
The temporal process projects superiorly to articulate with the temporal bone, forming the zygomatic arch.
Maxillary Process
The maxillary process projects laterally and articulates with the maxilla, forming the lateral wall of the orbit.
Zygomatic Arch
The zygomatic arch is formed by the union of the zygomatic bone’s temporal process with the temporal bone’s zygomatic process. It provides support for the cheek region.
The Mandible
The mandible, or lower jawbone, is the only movable bone of the skull. It consists of the following subparts:
Body
The body of the mandible forms the main portion of the jaw, supporting the teeth.
Ramus
The ramus is the ascending portion of the mandible and includes the condylar process and the coronoid process.
