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.

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.

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.

The process whose specific outcome is the progression of the inner ear over time, from its formation to the mature structure.

The process whose specific outcome is the progression of the inner ear over time, from its formation to the mature structure.

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.

The progression of a heart valve over time, from its formation to the mature structure. A heart valve is a structure that restricts the flow of blood to different regions of the heart and forms from an endocardial cushion.

The process in which relatively unspecialized cells acquire specialized structural and/or functional features of a type B pancreatic cell. A type B pancreatic cell is a cell located towards center of the islets of Langerhans that secretes insulin.

The progression of the proepicardium from its formation to the mature structure. The proepicardium is an outpouching of the septum transversum.

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

The process whose specific outcome is the progression of the pancreas over time, from its formation to the mature structure. The pancreas is an endoderm derived structure that produces precursors of digestive enzymes and blood glucose regulating enzymes.

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 regrowth of a lost or destroyed body part, such as an organ or tissue. This process may occur via renewal, repair, and/or growth alone (i.e. increase in size or mass).

The process whose specific outcome is the progression of the pectoral fin over time, from its formation to the mature structure.

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.

The process in which a relatively unspecialized cell acquires the specialized features of an astrocyte. An astrocyte is the most abundant type of glial cell. Astrocytes provide support for neurons and regulate the environment in which they function.

The process in which a relatively unspecialized cell acquires the specialized features of an oligodendrocyte. An oligodendrocyte is a type of glial cell involved in myelinating the axons of neurons in the central nervous system.

The process in which a relatively unspecialized cell acquires the specialized features of an iridophore. Iridophores are pigment cells derived from the neural crest. They contain guanidine or other purine crystals deposited in stacks called reflecting platets or iridisomes. This gives them a silver, gold, or iridescent appearance.

The biological process whose specific outcome is the progression of the roof of the mouth from an initial condition to its mature state. This process begins with the formation of the structure and ends with the mature structure. The roof of the mouth is the partition that separates the nasal and oral cavities.

The process whose specific outcome is the progression of the retina over time, from its formation to the mature structure. The retina is the innermost layer or coating at the back of the eyeball, which is sensitive to light and in which the optic nerve terminates.

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

The progression of the hepaticobiliary system over time, from its formation to the mature structure. The hepaticobiliary system is responsible for metabolic and catabolic processing of small molecules absorbed from the blood or gut, hormones and serum proteins, detoxification, storage of glycogen, triglycerides, metals and lipid soluble vitamins and excretion of bile. Included are the synthesis of albumin, blood coagulation factors, complement, and specific binding proteins.

The progression of the visceral serous pericardium from its formation to the mature structure. The visceral serous pericardium is the inner layer of the pericardium.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
