The formation of the notochord from the chordamesoderm. The notochord is composed of large cells packed within a firm connective tissue sheath and is found in all chordates at the ventral surface of the neural tube. In vertebrates, the notochord contributes to the vertebral column.

The tube morphogenesis process in which the primitive heart tube loops asymmetrically. This looping brings the primitive heart chambers into alignment preceding their future integration. Heart looping begins with dextral-looping and ends when the main regional divisions of the mature heart and primordium of the great arterial trunks become established preceeding septation.

The establishment of the lateral mesoderm with respect to the left and right halves.

The process in which the anatomical structures of the embryonic heart tube are generated and organized. The embryonic heart tube is an epithelial tube that will give rise to the mature heart.

The process in which the anatomical structure of the endocardium is generated and organized. The endocardium is an anatomical structure comprised of an endothelium and an extracellular matrix that forms the innermost layer of tissue of the heart, and lines the heart chambers.

The establishment of an organism's body plan or part of an organism with respect to the left and right halves. The pattern can either be symmetric, such that the halves are mirror images, or asymmetric where the pattern deviates from this symmetry.

The formation of a ventral region of glial cells in the neural tube that provides inductive signals for the specification of neuronal cell types. The floor plate is evident at the ventral midline by the neural fold stage.

The progression of the pineal gland over time from its initial formation until its mature state. The pineal gland is an endocrine gland that secretes melatonin and is involved in circadian rhythms.

The progression of the pineal gland over time from its initial formation until its mature state. The pineal gland is an endocrine gland that secretes melatonin and is involved in circadian rhythms.

The process whose specific outcome is the progression of the adrenal gland over time, from its formation to the mature structure. This gland can either be a discrete structure located bilaterally above each kidney, or a cluster of cells in the head kidney that perform the functions of the adrenal gland. In either case, this organ consists of two cells types, aminergic chromaffin cells and steroidogenic cortical cells.

The process whose specific outcome is the progression of the notochord over time, from its formation to the mature structure. The notochord is a mesoderm-derived structure located ventral of the developing nerve cord. In vertebrates, the notochord serves as a core around which other mesodermal cells form the vertebrae. In the most primitive chordates, which lack vertebrae, the notochord persists as a substitute for a vertebral column.

The progression of the glomerulus over time from its initial formation until its mature state. The glomerulus is a capillary tuft which forms a close network with the visceral epithelium (podocytes) and the mesangium to form the filtration barrier and is surrounded by Bowman's capsule in nephrons of the vertebrate kidney. The glomerulus is part of the nephron and is restricted to one body segment.

The progression of the floor plate over time from its initial formation until its mature state.

The process whose specific outcome is the progression of the embryonic heart tube over time, from its formation to the mature structure. The heart tube forms as the heart rudiment from the heart field.

The process in which the anatomical structures of the pronephric glomerulus are generated and organized. The pronephric glomerulus is part of the pronephric nephron and is restricted to one body segment.

Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.

Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.

The developmental process that results in the deposition of coloring matter in an organism, tissue or cell.

The process in which the anatomical structures of the axial mesoderm are generated and organized.

The process in which the anatomical structures of the axial mesoderm are generated and organized.

The process in which a cell becomes capable of differentiating autonomously into an axial mesoderm cell in an environment that is neutral with respect to the developmental pathway; upon specification, the cell fate can be reversed.

The process that contributes to the act of creating the structural organization of the axial mesoderm. This process pertains to the physical shaping of a rudimentary structure.

The process in which relatively unspecialized cells acquire specialized structural and/or functional features cells that make up the notochord. Differentiation includes the processes involved in commitment of a cell to a notochord cell fate.

The progression of a somite from its initial formation to the mature structure. Somites are mesodermal clusters that are arranged segmentally along the anterior posterior axis of an embryo.

Determination of the asymmetric location of the heart with respect to the left and right halves of the organism.

Any process that modulates the frequency, rate or extent of BMP signaling pathway involved in heart jogging.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
