The regionalization process in which specific areas of cell differentiation are determined along the anterior-posterior axis. The anterior-posterior axis is defined by a line that runs from the head or mouth of an organism to the tail or opposite end of the organism.

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

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

Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II.

The process in which a relatively unspecialized cell acquires specialized features of a neuron.

Any process that stops, prevents, or reduces the frequency, rate or extent of myeloid cell differentiation.

The specific behavior of an organism relating to grooming, cleaning and brushing to remove dirt and parasites.

Locomotory behavior in a fully developed and mature organism.

The series of events required for an organism to receive a painful stimulus, convert it to a molecular signal, and recognize and characterize the signal. Pain is medically defined as the physical sensation of discomfort or distress caused by injury or illness, so can hence be described as a harmful stimulus which signals current (or impending) tissue damage. Pain may come from extremes of temperature, mechanical damage, electricity or from noxious chemical substances. This is a neurological process.

The process whose specific outcome is the progression of the dorsal region of the spinal cord over time, from its formation to the mature structure. The dorsal region of the mature spinal cord contains neurons that process and relay sensory input.

Any process that stops, prevents, or reduces the frequency, rate or extent of myeloid cell differentiation.

The process in which the anatomical structures of the skeleton are generated and organized during the embryonic phase.

The process in which the anatomical structures of the skeleton are generated and organized during the embryonic phase.

The process whose specific outcome is the progression of the exocrine pancreas over time, from its formation to the mature structure. The exocrine pancreas produces and store zymogens of digestive enzymes, such as chymotrypsinogen and trypsinogen in the acinar cells.

The process whose specific outcome is the progression of the endocrine pancreas over time, from its formation to the mature structure. The endocrine pancreas is made up of islet cells that produce insulin, glucagon and somatostatin.

The process, occurring in the embryo, by which the anatomical structures of the pectoral fin are generated and organized. Pectoral fins are bilaterally paired fins mounted laterally and located behind the gill covers of fish. These fins are used for lateral mobility and propulsion.

Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II.

The multiplication or reproduction of cells, resulting in the expansion of a cell population.

The specification of the anterior/posterior axis of the embryo by the products of genes expressed maternally and genes expressed in the zygote.

Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.

Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.

The migration of a relatively undifferentiated cell along the developing posterior lateral line, originating from cranial ectodermal placodes situated behind the ear. The neuromast primordium deposits proneuromasts along the lateral line, from which the neuromasts will develop.

That part of the nuclear content other than the chromosomes or the nucleolus.

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.

The part of the cytoskeleton (the internal framework of a cell) composed of microtubules and associated proteins.
