Probing the Roles of Physical Forces in Early Chick Embryonic Morphogenesis
Published on: June 5, 2018
Summary
Embryonic development
Area of Science:
- Developmental biology
- Evolutionary biology
- Cell biology
Background:
- Embryonic development involves the formation of three primary germ layers: ectoderm, mesoderm, and entoderm.
- These germ layers are proposed to reflect a fundamental functional differentiation of cells observed throughout evolutionary history (phylogeny).
Purpose of the Study:
- To propose a framework for understanding the functional specialization of the three germ layers.
- To explore the evolutionary origins of cognitive and reasoning faculties within these germ layers.
Main Methods:
- Conceptual analysis of embryonic germ layer formation.
- Comparative analysis of proposed functional roles across phylogeny.
- Hypothesizing the evolutionary timeline of cognitive faculty development.
Main Results:
- The entoderm specializes in metabolism and homeostasis ('the body's chemist').
- The mesoderm specializes in structural organization ('the body's architect and engineer').
- The ectoderm specializes in environmental interactions ('the body's external affairs').
Conclusions:
- Cognitive and reasoning faculties are inherent in all germ layers.
- Each germ layer utilizes conceptual thought for its specialized functions.
- The entoderm and mesoderm developed cognitive faculties significantly earlier than the ectoderm in evolutionary history.

01:33Cleavage and Blastulation
After a large-single-celled zygote is produced via fertilization, the process of cleavage occurs while zygotes travel through the uterine tube. Cleavage is a mitotic cell division that does not result in growth. With each round of successive cell division, daughter cells get increasingly smaller.
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...
01:10Zygotic Development And Stem Cell Formation
The development of all multicellular organisms starts with the fusion of haploid cells called sperm and egg to form a diploid zygote. A zygote is a totipotent cell that can develop into a complete organism. The zygote undergoes cell division or cleavage to form an 8-cell mass. Until this stage, the cells are spherical, loosely attached, and remain totipotent. Totipotent cells are capable of developing both the embryonic and the extraembryonic tissues. However, as they continue to divide, they...
00:57Cellular Differentiation
How does a complex organism such as a human develop from a single cell? It all starts from a single fertilized egg which gives rise to a vast array of cell types, such as nerve cells, muscle cells, and epithelial cells that characterize the adult? Throughout development and adulthood, cellular differentiation leads cells to assume their final morphology and physiology. Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions.

01:15Development of the Sexual Organs in the Embryo and Fetus
Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the male...
