Summary
Crista galli (CG) size significantly increases with fetal development, while olfactory fossa depth remains constant. These findings aid in estimating fetal dimensions using linear growth patterns.
Area of Science:
- Fetal development and anatomy
- Cranial base morphology
Background:
- The crista galli (CG) is a key anatomical landmark in the cranial base.
- Understanding CG growth patterns is crucial for fetal development assessment.
Purpose of the Study:
- To investigate changes in crista galli (CG) dimensions throughout fetal development.
- To analyze the relationship between CG size and olfactory fossa depth (OFD) with gestational age.
Main Methods:
- Measurements of CG width, height, and length, along with OFD, were taken from 32 fetal skull bases (17-32 weeks gestation).
- Statistical analysis was performed to assess differences based on sex, gestational age, and trimester.
Main Results:
- CG dimensions (width, height, length) significantly increased with advancing gestational weeks, particularly in the third trimester.
- Olfactory fossa depth (OFD) showed no significant change with gestational age or trimester.
- Keros type 1 classification was observed in all fetuses studied.
Conclusions:
- Fetal crista galli size demonstrates significant growth correlated with advancing gestational weeks.
- Established linear functions can model the growth patterns of CG and OFD, aiding in prenatal dimensional estimations.

01:56Gastrulation
Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata will form...
01:20Embryonic Connective Tissues
During early development, the embryo forms two types of connective tissues— the mesenchyme and mucoid connective tissue.
The mesenchyme is the first connective tissue that emerges in the developing embryo. It consists of loosely arranged multipotent mesenchymal cells and reticular fibers in the extracellular matrix. This loose arrangement allows easy migration of cells, which is essential for germ layer positioning, patterning, and organ morphogenesis during embryonic development. Mesenchyme is...

01:16Vertebral Column: Regions and Curvature
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form the...

01:30General Structure of a Vertebra
A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous column.
01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

01:18Uterus and Cervix
The uterus, commonly called the womb, is a vital reproductive organ in females designed to provide a nurturing environment for the implantation and growth of an embryo. It is shaped like a hollow pear and positioned between the urinary bladder and the rectum. The uterus's structure allows it to support and protect a developing fetus throughout pregnancy.
The uterus is securely anchored within the pelvic cavity by paired broad ligaments on either side. It is further stabilized by three pairs of...
