The primitive node (or primitive knot) is the organizer for gastrulation in most amniote embryos. In birds, it is known as Hensen's node, and in amphibians...

central pair of microtubules are found in the cells of the embryonic primitive node; termed nodal cells, these nodal cilia are responsible for the left-right...

serves as the basis for the nervous system. Cranial to the primitive node of the embryonic primitive streak, ectodermal tissue thickens and flattens to become...

The progenitor notochord is derived from cells migrating from the primitive node and pit. The notochord forms during gastrulation and soon after induces...

fertilized eggs occurs early in development. Partial splitting of the primitive node and streak may result in the formation of conjoined twins. These twins...

knob-like thickening termed the primitive node or knot, (known as Hensen's knot in birds). A shallow groove, the primitive groove, appears on the surface...

tree of primitive Pythagorean triples is a mathematical tree in which each node represents a primitive Pythagorean triple and each primitive Pythagorean...

embryogenesis, playing a key role in signal transfer from the primitive node, in the anterior primitive streak, to lateral plate mesoderm (LPM). Nodal signaling...

of the epiblast to the center midline. The primitive node is situated at the anterior end of the primitive streak and serves as the organizer for gastrulation...

In computer science, a binary tree is a tree data structure in which each node has at most two children, referred to as the left child and the right child...

and so rotate clockwise rather than beat; in the primitive node at the anterior end of the primitive streak in the embryo, these are angled posteriorly...

objects, potentially generating visually complex objects by combining a few primitive ones. In 3D computer graphics and CAD, CSG is often used in procedural...

In other words, every primitive triple will be a "parent" to three additional primitive triples. Starting from the initial node with a = 3, b = 4, and...

2n grid nodes. Therefore, at points close to the grid nodes, the output will approximate the dot product of the gradient vector of the node and the offset...

three geometric primitives: A node is a point with a geographic coordinate expressed in the WGS 84 coordinate system. A standalone node represents a point...

expression in the portion of the primitive streak that will differentiate into the node (also referred to as the primitive node). The PEE turns on Nodal expression...

stroke for cilia.3 During early development, the cilia found on the primitive node will beat in a directional pattern, sending signaling molecules to the...

node-based workflow. With MCG the user can create a new plug-in for 3ds Max in minutes by simply wiring together parameter nodes, computation nodes,...

responsible for gastrulation, left-right patterning and induction of the primitive node. As NODAL protein diffuse through an embryo, it triggers Nodal Signaling...
