| cartilage development |
The process whose specific outcome is the progression of a cartilage element over time, from its formation to the mature structure. Cartilage elements are skeletal elements that consist of connective tissue dominated by extracellular matrix containing collagen type II and large amounts of proteoglycan, particularly chondroitin sulfate. |
| cell differentiation |
The process in which relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state. |
| embryonic viscerocranium morphogenesis |
The process in which the anatomical structures of the viscerocranium are generated and organized during the embryonic phase. The viscerocranium is the part of the skull comprising the facial bones. |
| negative regulation of photoreceptor cell differentiation |
Any process that stops, prevents, or reduces the frequency, rate or extent of photoreceptor cell differentiation. An example of this process is found in Drosophila melanogaster. |
| negative regulation of transcription by RNA polymerase II |
Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II. |
| neural crest cell development |
The process aimed at the progression of a neural crest cell over time, from initial commitment of the cell to its specific fate, to the fully functional differentiated cell. |
| peripheral nervous system development |
The process whose specific outcome is the progression of the peripheral nervous system over time, from its formation to the mature structure. The peripheral nervous system is one of the two major divisions of the nervous system. Nerves in the PNS connect the central nervous system (CNS) with sensory organs, other organs, muscles, blood vessels and glands. |
| pharyngeal system development |
The process whose specific outcome is the progression of the pharyngeal system over time, from its formation to the mature structure. The pharyngeal system is a transient embryonic complex that is specific to vertebrates. It comprises the pharyngeal arches, bulges of tissues of mesoderm and neural crest derivation through which pass nerves and pharyngeal arch arteries. The arches are separated internally by pharyngeal pouches, evaginations of foregut endoderm, and externally by pharyngeal clefts, invaginations of surface ectoderm. The development of the system ends when the stucture it contributes to are forming: the thymus, thyroid, parathyroids, maxilla, mandible, aortic arch, cardiac outflow tract, external and middle ear. |
| positive regulation of amacrine cell differentiation |
Any process that activates or increases the frequency, rate or extent of amacrine cell differentiation. |
| positive regulation of cell differentiation |
Any process that activates or increases the frequency, rate or extent of cell differentiation. |
| regulation of transcription by RNA polymerase II |
Any process that modulates the frequency, rate or extent of transcription mediated by RNA polymerase II. |
| ribosome biogenesis |
A cellular process that results in the biosynthesis of constituent macromolecules, assembly, and arrangement of constituent parts of ribosome subunits; includes transport to the sites of protein synthesis. |
