96 Hour Chick Embryo Serial Section
With the use of serial cross-sections of chicken embryos, you are about to embark. Notice that by 24 hours, the chicken embryo already demonstrates an axis of. Chick Embryo 96 Hours Serial Sag Section Prepared Microscope Slide Triarch Incorporated 96 hr chick; serial sagital section.
At about 33 hours after fertilization, the embryo is about 4 mm long and the first flexion of the originally straight embryo starts in the head region. The cranial flexure will be visible a few hours later. At this stage 12 to 13 somites are formed. The eye vesicles are rather large. The forebrain vesicle or prosencephalon will divide, the midbrain vesicle or mesencephalon remains undivided while the hindbrain vesicle or rhombencephalon will form a series of smaller neuromeres. The sinus rhomboidalis (diamond-shaped) is still present as the only opening of the neural tube and the primitive streak is only rudimentary. The infundibulum (= derived from the diencephalon) appears as a half circular structure at the ventral side of the caudal part of the forebrain.
The notochord or chorda dorsalis ends just behind this ventral vesicle. Later on, 36 hours after fertilization, the heart, which has a bilateral origin in the mesodermal layer, is a S-shaped tube which protrudes to the right of the embryo (in upper view). Outside, in the area vasculosa (= forseen of blood vessels) the formation of blood islands continues.
The primitive streak can only still be discerned below the sinus rhomboidalis. Early embryonic developmental features that are shown on this page: • Whole mount preparation 33 hours () • Whole mount preparation 36 hours () • Cross sections 36 hrs; formation of eye, heart and intestines ( ) Stage 33 hours Information: At about 33 hours after fertilization, the embryo is about 4 mm long and the first flexion of the originally straight embryo starts in the head region and the cranial flexure will be visible a few hours later. At this stage 12 to 13 somites are formed. The eye vesicles are rather large.
The forebrain vesicle or prosencephalon will divide, the midbrain vesicle or mesencephalon remains undivided while the hindbrain vesicle or rhombencephalon will form a series of smaller neuromeres. The sinus rhomboidalis (diamond-shaped???) is still present as the only opening of the neural tube and the primitive streak is only rudimentary.
The infundibulum (= derived from the diencephalon) appears as a half circular structure at the ventral side of caudal part of the forebrain. The notochord or chorda dorsalis ends just behind this venral vesicle.

Philadelphia: P. Blakiston's Son and Co. Stage 36 hours Information: 36-hours after fertilization, the heart is a S-shaped tube which protude to the right of the embryo (in upper view). The further development of the heart is now mesodermal. Outside, in the area vasculosa (= forseen of blood vessels) the formation of blood islands continues.
The primitive streak can only still be discerned below the sinus rhomboidalis.
Another Way To Look at Serially Sectioned Frog and Chick Embryos What we show here is the first part of a project we call '4-D Embryology--Embryos in Three Dimensions and Their Changes Over Time.' We captured digital images of all the sections of serially sectioned embryos. Zhurnal predmetno kolichestvennogo ucheta lekarstvennih sredstv obrazec. We then used the sequence of images of an embryo to make a QuickTime digital movie. After we made movies of several serially sectioned frog and chick embryos, we started using them in our developmental biology labs. Students like watching and using these QuickTime movies to learn about developing embryos, and we want to share these movies with other students of developmental biology. What you can see here are small 'postage-stamp' versions of these movies of serially sectioned frog and chick embryos.
