Summary
This study measured sphenoid ridge (SR) dimensions and angles in fetuses, finding that most parameters increase with gestational age, aiding prenatal development understanding.
Area of Science:
- Fetal anatomy and development
- Cranial base morphology
Background:
- The sphenoid ridge (SR) is a crucial anatomical landmark in the cranial base.
- Understanding its prenatal development is essential for neurosurgery and anatomy.
Purpose of the Study:
- To quantify the size and angle of the sphenoid ridge (SR) in fetal specimens.
- To analyze the developmental trends of SR parameters throughout gestation.
Main Methods:
- Measurements of sphenoid ridge length (SRL), angle (SRA), and widths (SRW-ML, SRW-MP, SRW-L) were performed on 32 fetal skull bases (17-32 weeks gestation).
- Statistical analysis was conducted to assess differences based on sex, gestational trimester, and gestational age.
Main Results:
- SRL, SRW-ML, SRW-MP, and SRW-L increased with gestational age, particularly in the third trimester.
- Sphenoid ridge angle (SRA) remained consistent across trimesters and gestational weeks.
- No significant sex or side-based differences were observed in SR measurements.
Conclusions:
- This study provides valuable normative data on fetal sphenoid ridge development.
- The derived regression equations can predict SR parameters based on fetal age.
- Findings are beneficial for neurosurgeons and anatomists involved in prenatal assessments.

01:27Cranial Bones: Lateral View
2.0K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:22Sutures of the Skull
6.3K
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...

01:14Cranial Bones: Superior and Posterior View
2.0K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:30Neurulation
41.7K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...
