Development is a dynamic process with structures changing (shape, name and relationships) over time and the best way to show this is with dynamic images, such as movies. This first page introduces the various movies and animations in UNSW Embryology that illustrate various aspects of development.
There are 2 ways to watch each movie. Firstly, click the image or text link to open a new page with both the movie and a more detailed text description of features that can be seen. Secondly, the link below the images and text labelled Quicktime with the movie name and (file size) will open only the movie in a new window.
This first series of movies show human embryonic growth and some other whole embryos.
Other Movie Pages: Embryo Growth | Ultrasound | Abnormal Ultrasound | Week 1 | Week 2 | Week 3 | Week 4 | Stage 13/14 | 3D Model | Stage 22 | Neural | Mesoderm | Head and Neck | Heart | Vasculature | Gastrointestinal | Endocrine | Urogenital | Other Embryo | Larsen | Historic | Internet | Commercial
Embryonic stage images are to scale so growth of the embryo as well as the appearance of external features can be observed. Note the changing proportions of the embryo and elongation and rotation of the limbs.
Quicktime: stages.mov (90 Kb)
Alternative movie of Carnegie stage 11 to 23 of human development. Embryonic stage images are to scale so growth of the embryo as well as the appearance of external features can be observed. Note the changing proportions of the embryo and elongation and rotation of the limbs.
Quicktime: Embryo.mov (88 Kb)
Movie of human head development covering Carnegie stages 15 to 22. The movie starts with the pharyngeal arches (a series of external bulges) which form structures of the head and neck.
External ear- on the side of the head the first 2 arches contribute a series (3 on each) of smaller bulges which will form the external ear. Watch also the changing relative position of these bulges, initially at the level of the neck and, as the head and jaw develop, gradually rising to near their final position on the side of the head.
The stage images have been enlarged to allow details to be seen and are therefore not to scale.
Quicktime: CSthead.mov (179 Kb)
Movie of human upper limb development covering Carnegie stages 13 to 23.
The upper limb begins as a small lateral "bud" on the side of the embryo, which as is grows develops a "fan-shaped" primordial hand with webbed digits. Note as the upper limb lengthens how it rotates and flexes, to finally end at stage 23 bent anteriorly to the upper body.
The stage images have been enlarged to allow details to be seen and are therefore not to scale.
Quicktime: stage/arm.mov (179 Kb)
A movie of the growth of the mouse embryo made by Brad Smith.
This movie made from a series of different individual embryo images, the last images in the movie are x-ray images (?) showing sites of early ossification (bright white regions) in the long bones of the embryo. Note the changing proportions of head to body (compare with human) and the persistance of the tail as an extension of the vertebral column.
Quicktime: Growth.mov (340 Kb)
A movie which rotates the stage 13/14 pig embryo model.
At this stage of development, the pig and human embryo are approximately the same in external features.
This model corresponds to the same stage as the serial slices, and you should attempt to compare the external features with the internal structures seen in the serial slice images.
Note the movie can be stopped and started to see specific surface features.
Quicktime: Pig.mov (612 Kb)

UNSW Embryology has many movies to show some of the dynamic changes that occur during development. These have been grouped together on separate pages (listed in righthand menu) that can be also be opened from a pull down menu on each page.
Internet users note that some of these movies are large and will take some time to download depending on your connection speed.
There also an about movies page which has technical details and terms listed.
Both Mac and PC computers require the Quicktime plug-in to be present in your browser or on your computer.
CD users can find Quicktime on the CD or the latest version can be downloaded from here Quicktime
