Few Useful Embryology Atlases Websites
Embryology from Henry Gray Anatomy of the Human Body is available at
This 20th edition (1918) has embryology illustrations that may be searchable
by keyword or by a table of contents or directly browsed by thumbnail. An encyclopedic
subject index with hyperlinks to the respective pages is also available.
2. Visible Embryo at http://www.visembryo.com/
is "a comprehensive resource of information on human development from conception
to birth, designed for both medical student and interested lay people". This
interesting site "offers a detailed pictorial account of normal and abnormal
development." Visembryo is a resource of information on human development
from conception to birth. It offers a pictorial representation of normal and abnormal
development in a 23 stages spiral that navigates the 40 weeks of pregnancy.
3. An Atlas of Human Embryogenesis at http://www.bioscience.org/atlases/fert/indexa.htm
has instructive material on uterus, fetus, amnion and placenta, pregnant uterus,
embryogenesis, transfer across the placental membrane, chorionic villus sampling
and amniocentesis, delivery and the mature placenta. This site is a part of Frontiers
Images of Embryo is a tutorial available at http://www.med.unc.edu/embryo_images/unit-welcome/welcome_htms/contents.htm
This tutorial developed by Drs. K K. Sulik and P R. Bream Jr. has line drawings
used with permission from Lippincott Williams & Wilkins. Scanning Electron
Micrographs (SEMs) are the primary resource in the Atlas to teach mammalian embryology
with a majority of micrographs of mouse and human embryos. "The 3-D like
quality of the micrographs coupled with selected line drawings and minimal text
allow relatively easy understanding of the complex morphological changes that
occur in utero"
5. The Multi-Dimensional Human Embryo at
is "a collaboration funded by the National Institute of Child Health and
Human Development (NICHD) to produce and make available over the Internet a three-dimensional
image reference of the Human Embryo based on magnetic resonance imaging. The collection
of images is intended to serve students, researchers, clinicians, and the general
public interested in studying and teaching human development". Important
features include an Human embryo atlas (image slice selector) and a Dataset download.
6. Embryology Collaborative at http://isc.temple.edu/marino/embryo/defaulthold.htm
is an embryology resource site crafted by Thomas A. Marino, Ph.D that has some
of the best resources for understanding the development of a particular organ
system or systems. The material focuses on early embryology, development of the
back and spinal cord, limbs, systems such as cardiovascular, respiratory, gastrointestinal,
kidneys, reproductive, face, head and neck and the brain.
has been principally designed to complement the Embryology curriculum at McGill
University's Faculty of Medicine. It has essentially, four units that cover broad
areas such as molecules, cells, and tissues; fluids and electrolytes ;the life
cycle and endocrinology metabolism and nutrition. Interestingly, an Embryology
Timeline Indicator, is available at http://sprojects.mmi.mcgill.ca/embryology/timelineframe.htm
8. Embryology from the University of New South Wales is available
This site developed by Dr Mark Hill, has many graphical illustrations sets and
is enriched by features such as Carnegie Stages, Development Notes (give information
about early developmental processes)., System Notes, Movies (displaying the dynamic
processes of development) and Class Notes. Each section of "Notes" is
organized in a similar way giving: an introduction, overview, developmental abnormalities,
histology and developmental molecular mechanisms. To illustrate the GIT Notes
are available at http://anatomy.med.unsw.edu.au/cbl/embryo/Notes/git.htm
while Placenta Notes is available at http://anatomy.med.unsw.edu.au/cbl/embryo/Notes/placenta.htm
Current affairs of public interest, such as "Embryology in the News"
(stem cells cloning) is also available.
9. The Story of the
Development and Maldevelopment of the Brain at http://www.vh.org/Providers/Textbooks/FetalYoungCNS/FetalYoungCNS.html
is created from the Department of Anatomy of University of Iowa College of Medicine.
The contents include germ layers, embryogenesis (formation of embryo), brain development:
histogenesis. Additionally, causes of brain malformations, malformations of neural
tube defects and malformations of histogenesis are also dealt with. Other features
that are of interest include sections on "Structural - Functional Correlation"
and "Lessons Learned from Functional Imaging".
Genitourinary Development at http://www.meddean.luc.edu/lumen/MedEd/urology/guhome.htm
is a tutorial correlating Genitourinary embryology with congenital anomalies.
David A. Hatch, M.D. from Loyola University, has produced this site. The material
is classified into sections that deal with Imaging of congenital genitourinary
defects, bladder, kidney, penis/urethra, scrotum/testis, ureter.
Neuroembryology at http://courses.temple.edu/neuroanatomy/lab/embryo/
features graphic educative material on neural tube, spinal cord, cerebellum, midbrain,
diencephalon/telencephalon and ventricular system. Cardiac Embryology from
Rush Children's Heart Center is available at http://www.rchc.rush.edu/rmawebfiles/Embryology.htm
. Gut Embryology at http://www.med.unc.edu/embryo_images/unit-digest/digest_htms/digesttoc.htm
has illustrative graphics dealing with foregut, liver, lung, pancreas, midgut
and hindgut formation.
The Human Embryology Website at http://www.med.uc.edu/embryology/
supports the current editions of Human Embryology and Essentials Of Human Embryology,
(W.J. Larsen: Churchill Livingstone Inc.). The site provides Animations of developmental
processes, Self-testing exercises, and Updates and links.
particularly useful set of Embryology Links relevant to the radiologist
is available at http://www.pediatricradiology.com/#5
