Head & Neck Anatomy: Skull Anatomy Flashcards

Sutural Ligament

The layer of connective tissue situated between skull bones at immobile joints called sutures.

Diploe

The layer of spongy bone situated between the external and internal tables of compact bone in the skull.

Cranium

The upper and posterior region of the skull consisting of 8 cranial bones that enclose and protect the brain.

Facial Skeleton

The anterior part of the skull composed of 14 facial bones.

Coronal Suture

The major cranial suture that attaches the frontal bone anteriorly to the parietal bones posteriorly.

Sagittal Suture

The midline suture located between the two parietal bones, extending from the coronal suture to the lambdoid suture.

Lambdoid Suture

The suture on the posterior aspect of the skull separating the occipital bone from the parietal bones.

Squamous Suture

The suture forming the boundary between the temporal bone and the parietal bone on each side of the skull.

Norma Frontalis

The anterior view of the skull, composed of the frontal bone, zygomatic bones, maxillae, and mandible.

Norma Verticalis

The superior view of the skull cap.

Norma Lateralis

The lateral view of the skull.

Norma Occipitalis

The posterior view of the skull.

Norma Basalis

The inferior view of the external base of the skull.

Glabella

A median elevation on the frontal bone located between the two supraciliary arches above the root of the nose.

Nasion

The anatomical landmark marking the meeting point of the frontonasal and internasal sutures.

Supraorbital Notch

A opening or notch located at the junction between the medial 1/3 and lateral 2/3 of the superior orbital margin that transmits the supraorbital nerve and vessels.
