| auditory receptor cell fate specification |
The process in which a cell becomes capable of differentiating autonomously into an auditory hair cell in an environment that is neutral with respect to the developmental pathway; upon specification, the cell fate can be reversed. |
| camera-type eye development |
The process whose specific outcome is the progression of the camera-type eye over time, from its formation to the mature structure. The camera-type eye is an organ of sight that receives light through an aperture and focuses it through a lens, projecting it on a photoreceptor field. |
| 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. |
| endocrine system development |
Progression of the endocrine system over time, from its formation to a mature structure. The endocrine system is a system of hormones and ductless glands, where the glands release hormones directly into the blood, lymph or other intercellular fluid, and the hormones circulate within the body to affect distant organs. The major glands that make up the human endocrine system are the hypothalamus, pituitary, thyroid, parathryoids, adrenals, pineal body, and the reproductive glands which include the ovaries and testes. |
| inner ear receptor cell development |
The process whose specific outcome is the progression of an inner ear receptor cell over time, from its formation to the mature structure. Cell development does not include the steps involved in committing a cell to a specific fate. |
| lens fiber cell differentiation |
The process in which a relatively unspecialized cell acquires specialized features of a lens fiber cell, any of the elongated, tightly packed cells that make up the bulk of the mature lens in the camera-type eye. The cytoplasm of a lens fiber cell is devoid of most intracellular organelles including the cell nucleus, and contains primarily crystallins, a group of water-soluble proteins expressed in vary large quantities. |
| 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. |
| neuron development |
The process whose specific outcome is the progression of a neuron over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell. |
| olfactory placode formation |
The formation of a thickening of the neural ectoderm in the head region of the vertebrate embryo which develops into the olfactory region of the nasal cavity. |
| otic placode formation |
The initial developmental process that will lead to the formation of the vertebrate inner ear. The otic placode forms as a thickening of the head ectoderm adjacent to the developing hindbrain. |
| otic vesicle formation |
The process resulting in the transition of the otic placode into the otic vesicle, a transient embryonic structure formed during development of the vertebrate inner ear. |
| otic vesicle morphogenesis |
The process in which the anatomical structures of the otic vesicle are generated and organized. The otic vesicle is a transient embryonic structure formed during development of the vertebrate inner ear. |
| regulation of transcription by RNA polymerase II |
Any process that modulates the frequency, rate or extent of transcription mediated by RNA polymerase II. |
| trigeminal nerve development |
The process whose specific outcome is the progression of the trigeminal nerve over time, from its formation to the mature structure. The trigeminal nerve is composed of three large branches. They are the ophthalmic (V1, sensory), maxillary (V2, sensory) and mandibular (V3, motor and sensory) branches. The sensory ophthalmic branch travels through the superior orbital fissure and passes through the orbit to reach the skin of the forehead and top of the head. The maxillary nerve contains sensory branches that reach the pterygopalatine fossa via the inferior orbital fissure (face, cheek and upper teeth) and pterygopalatine canal (soft and hard palate, nasal cavity and pharynx). The motor part of the mandibular branch is distributed to the muscles of mastication, the mylohyoid muscle and the anterior belly of the digastric. The mandibular nerve also innervates the tensor veli palatini and tensor tympani muscles. The sensory part of the mandibular nerve is composed of branches that carry general sensory information from the mucous membranes of the mouth and cheek, anterior two-thirds of the tongue, lower teeth, skin of the lower jaw, side of the head and scalp and meninges of the anterior and middle cranial fossae. |
