Course Introduction

Dr Mark Hill

Course coordinator

This first lecture will be a general introduction to the course and the subject of Embryology.


Firstly, an introduction to the course, its content, method of presentation, assessment and an opportunity to ask questions.
Secondly, some historic background to the subject and related current Australian trends. I do not expect you to remember specific historic dates or statistical data, this is provided as an introduction to the topic.


I like my lectures to be interactive, so ask me questions and I will also be asking you questions!

  • The frog was used by many of the early embryology investigators and currently there are many different molecular mechanisms concerning development of the frog.
  • The eggs develop independently, in relative synchrony and are relatively see-through making staging and observation fairly easy.
  • The frog was a key model for the study of the process of gastrulation.

  • The chicken embryo develops and hatches in 20-21 days and historically these were one of the first embryos to be studied. Cutting a window in the egg shell allows direct observation of the embryo. The Hamburger & Hamilton chicken development staging allowed researchers to develop this model as a key embryological tool.
  • Key research involved the transplanting of quail cells into chick embryos, to later identify their contribution to different embryonic structures, particularly for somite, neural tube and neural crest development.

Historic Embryology - Mouse 
  • The mouse has always been a good embryological model, easy to generate (litters 8-20) and quick (21d).
  • Mouse embryology really expanded when molecular biologists used mice for gene knockouts.
Fly-icon.png
Fly Development - The fruitfly (drosophila) was and is the traditional geneticist's tool. It has been transformed to an magnificent embryologist's tool, with developmental mechanisms being uncovered in this system combined with homolgy gene searches in other species. The fly genome was one of the first to be been completely sequenced. In early development nurse cells sacrifice their cytoplasmic contents to allow egg growth and early pattern formation is through the localization of maternal messenger RNAs (mRNAs).
C elegans.jpg
Worm Development - Early embryological studies of the worm Caenorhabditis elegans (C.Elegans, so called because of its "elegant" curving movement) characterized the fate of each and every cell in the worm through all stages of development. This worm has recently had its entire genome sequenced.
Zebrafish-icon.png
Zebrafish Development - Zebrafish are seen as the latest and greatest "model' for embryological development studies. They can be easily genetically altered and develop as practically "see through" embryos, all internal development can be clearly observed from the outside in the living embryo.

Average maternal age in 2013 was 30.1 years, the same as 2009 but still more than the earlier years (2000, 29.0 years; 2002, 29.4 years). Birth number was 309,489 babies in 2013, an increase of 20% from 256,925 in 2003. Assisted Reproductive Technology (ART) was used by 3.8% (2009, 3.6%) of women who gave birth.

Obstructive Defect of the Renal Pelvis Obstructive Defects of the Renal Pelvis (obstructive defects of the renal pelvis, uteropelvic junction obstruction, pelvo-uterero junction obstruction) Term describing a developmental renal abnormality due to partial or complete blockage of the drainage of the kidney pelvis requiring surgical correction. The blockage can also have several causes including: unusual ureter twisting or bending, ureter compression by a blood vessel, malformations of the muscular wall. The blockage leads to an accumulation of urine in the affected region, with several potential effects: nephron damage from compression (hydronephrosis); decreased urine output leading to lack of amniotic fluid (oligohydramnios); respiratory development effects due to the lack of amniotic fluid.
  • The most common type of obstruction is at the uteropelvic junction (UPJ), between the junction of the ureter and the kidney.
  • Blockage lower as the ureter enters the bladder, the ureterovesicular junction (UVJ), usually involves only one kidney and the back flow enlarges the affected ureter (megaureter).

Congenital dislocation hip Congenital Dislocated Hip (More? Musculoskelal Abnormalities - Congenital Dislocation of the Hip (CDH))

(DHH, congenital dislocated hip, congenital hip dislocation, congenital hip dysplasia) Term describes a spectrum of musculoskeletal disorders of hip instability due either to the femoral head being able to move outside the acetabulum (luxation or dislocation), or abnormally within the acetabulum (subluxation or partial dislocation). This includes presentation following a normal examination of the hips in the newborn period (Ortolani and Barlow tests). When detected can be managed with splinting (Denis-Browne splint) allows the hip joint to develop normally and does not require surgery. If undetected and left untreated, the hip joint develops abnormally and surgical reduction is required. (More? Musculoskeletal System Development)
