paraxial

Swirl embryos, for example, have much enlarged paraxial mesoderm, the forming somites encircle the entire embryo (Figure 5F), and ventrally derived structures such as blood and the ventral tail fin are reduced or lacking entirely (57).

Nobel Lecture The Identification Of Genes Controlling Development In Flies And Fishes 1995

A longitudinal groove appears on the dorsal surface of either half and divides it into a medial column, the paraxial mesoderm, lying on the side of the neural tube, and a lateral portion, the lateral mesoderm.

I. Embryology. 5. Segmentation of the Fertilized Ovum 1918

The mesoderm in the floor of the groove connects the paraxial with the lateral mesoderm and is known as the intermediate cell-mass; in it the genito-urinary organs are developed.

The embryo is more completely separated from the yolk-sac, and the paraxial mesoderm is being divided into the primitive segments (Fig. 58).

I. Embryology. 14. The Form of the Embryo at Different Stages of Its Growth 1918

Toward the end of the second week transverse segmentation of the paraxial mesoderm begins, and it is converted into a series of well-defined, more or less cubical masses, the primitive segments (Figs. 18, 19, 20), which occupy the entire length of the trunk on either side of the middle line from the occipital region of the head.

I. Embryology. 8. The Primitive Segments 1918

On either side of it is a column of paraxial mesoderm which becomes subdivided into a number of more or less cubical segments, the primitive segments (Figs. 19 and 20).

II. Osteology. 1. Development of the Skeleton 1918

The current study was carried out to test whether any of the five major signaling pathways are regulated by tbx16 during two specific stages of mesoderm development: primitive red blood cell formation in the intermediate mesoderm and somite formation in the tail paraxial mesoderm.

Organized by subject, the book begins with the fundamental law of geometric optics, Snell's law of refraction, and states the paraxial ray trace equations, then moves on to thin lenses and increasingly more sophisticated components and multi-element systems.

Two representative light rays, one paraxial and one traveling through the center of the lens (the principal ray), are employed to establish the parameters of the imaging situation.
