|January 1, 1982
Summary
This study details the development of the mandibular canal in fetal mandibles, including key foramina and processes. Understanding these anatomical changes is crucial for potential clinical applications.
Area of Science:
- Anatomy
- Developmental Biology
- Oral and Maxillofacial Surgery
Background:
- The mandibular canal is a critical anatomical structure within the developing mandible.
- Its formation influences the development of surrounding bony structures and neurovascular bundles.
- Understanding its embryological development is essential for interpreting congenital anomalies and surgical approaches.
Purpose of the Study:
- To describe the developmental process of the mandibular canal in fetal mandibles.
- To analyze the concurrent development of the foramen mandibulae, foramen mentale, and lingula.
- To investigate morphological changes in the mandible associated with mandibular canal development.
Main Methods:
- Examination of 50 fetal mandibles.
- Detailed anatomical description of the mandibular canal and related structures.
- Morphological analysis correlating mandibular canal development with overall mandibular changes.
Main Results:
- The study provides a comprehensive description of mandibular canal development.
- Key foramina (mandibulae, mentale) and the lingula develop in conjunction with the canal.
- Significant morphological alterations in the mandible are observed secondary to the canal's development.
Conclusions:
- The development of the mandibular canal is a complex process intricately linked to the formation of other mandibular structures.
- The findings offer insights into normal mandibular morphogenesis.
- The anatomical details elucidated may have direct clinical relevance in pediatric dentistry, orthodontics, and maxillofacial surgery.

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...
01:30Neurulation
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 anterior...
01:29Bone Formation by Intramembranous Ossification
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...

01:09Changes in the Appendicular Skeleton with Age
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

01:27Development of the Heart
The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart tube by...

01:07Development of Blood Vessels
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...
