3D Adrenal (Suprarenal) Gland Embryology - Development of Adrenal Cortex and Adrenal Medulla
The video lecture by Dr. Aizaz from medicalvisual.com talks about the development of the adrenal glands or suprarenal glands.
00:00 Intro to Adrenal Gland (Supra-renal gland)
01:39 Location of embryological origin of Suprarenal glands
03:28 Formation of Adrenal Cortex (Fetal cortex and Adult Cortex)
06:02 Development of Adrenal Medulla from Neural Crest cells
11:24 Translocation of Adrenal Medulla to deep inside the adrenal gland
14:38 Different layers of the adrenal cortex
17:09 Ascent of Kidneys and fate of Adrenal glands
The adrenal glands consist of two different types of structures, the adrenal cortex and adrenal medulla. The cortex is further subdivided into three layers, while the medulla is a single layer. The cortex is mesodermal in origin, while the medulla is ectodermal, specifically neuroectodermal. The adrenal glands develop between the mesentery and the urogenital ridge from the celomic epithelium, with neural crest cells forming the medulla. The fetal adrenal cortex arises from the first wave of proliferated cells from the celomic epithelium, while the adult cortex arises from another wave of proliferated cells. The neural crest cells form the adrenal medulla and some ganglias in different parts of the body. The neural crest cells are like ambassadors of the central nervous system to different parts of the body, forming important structures.
The adrenal glands, or suprarenal glands, are two different types of structures consisting of the adrenal cortex and adrenal medulla, which are mesodermal and ectodermal in origin, respectively. Dr. Aizaz explains that the adrenal glands develop between the mesentery and the urogenital ridge from the celomic epithelium, with neural crest cells forming the medulla. The fetal adrenal cortex arises from the first wave of proliferated cells from the celomic epithelium, while the adult cortex arises from another wave of proliferated cells.
Dr. Aizaz also talks about the development of the medulla, which arises from neural crest cells that form important structures in different parts of the body, including the adrenal medulla and some ganglias. Neural crest cells act as representatives or ambassadors of the central nervous system to different parts of the body, forming important structures.
Overall, the video provides a simple and easy-to-understand explanation of the development of the adrenal glands, highlighting the differences in origin and function between the cortex and medulla, and the important role played by neural crest cells in the development of the adrenal medulla and other structures in the body.

Plzz make detailed animated video on testes development I am unable to understand how sex cords develop into seminiferous tubules your animation have helped me a lot in my 1st year and also I am dependent on your animations for my 2nd year embryo too am your subscriber too plzzz it's a request.

Development of testes has been taught in a great detail in three parts visual lecture series in our "Premium 3D Urogenital Embryology MasterClass", available here: www.medicovisual.com/courses/premium-urogenital-system-3d-masterclass Please email at draizaz@medicovisual.com or WhatsApp at +923037241030 if you need any help or have any question.
Sir, i have a confusion , you told that coelomic epithelium ( lateral plate mesoderm )forms adrenal cortex but my teacher told that adrenal cortex is contributed by mesonephric tubules which is actually derived from intermediate mesoderm. Please reply soon.

Hi, Very interesting question, indeed. Most of the major textbooks of Embryology (see references below), clearly state that the coelomic mesothelium proliferates and migrates towards the underlying mesenchyme to form the adrenal cortex. Nonetheless, some books (for example, Developmental Biology by Michael J. F. Barresi on it's page no. 541 and Clinical Embryology by Robert Carachi on page no. 27), explicitly state the intermediate mesoderm as a source of adrenal cortex. These books fail to explain any logical mechanism, as per my literature review. This might be the reason why your teacher told this. Interestingly, one of the textbook named "Human Embryology and Developmental Biology" by "Bruce M. Carlson" on page no. 107 states that intermediate mesoderm is the source of adrenal cortex but the same book at page no. 374 specifically states that "adrenocortical primordia appear during the fourth week as thickenings of the *coelomic mesothelium* at the cranial end of the genital ridge". This is the contradiction of their own statement 😂 Please note that the celomic mesothelium refers to somatopleuric mesoderm which originates from the "Lateral Plateral Mesoderm" (and not the intermediate mesoderm). *My References that assert that lateral plate mesoderm being the source of adrenal cortex:* 1. Moore's Developing Human 10th edition p. 75 -> Lateral Plate 2. Larsen's Human Embryology p. 391 3. Langman's Medical Embryology p. 346 4. Human Embryology and Developmental Biology by Bruce Carlson p. 374 -> Lateral Plate 5. Human Embryology Made Easy by Abdul Hameed Rana p. 276 6. Inderbir Singh's Human Embryology 11th edition p. 315 Also, can you please ask the same question to your teacher too? I want to see his take on this. You can contact me on WhatsApp at +923037241030 Best regards, Dr. Aizaz MedicoVisual
