The characteristic movement of cells from the dorsal ridge of the neural tube to a variety of locations in a vertebrate embryo.

The process in which the anatomical structures of the trabecular cardiac ventricle muscle are generated and organized.

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.

The process aimed at the progression of a Schwann cell over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell. Schwann cells are found in the peripheral nervous system, where they insulate neurons and axons, and regulate the environment in which neurons function.

The process in which neuroblasts acquire specialized structural and/or functional features that characterize the mature eurydendroid cell. Differentiation includes the processes involved in commitment of a neuroblast to a eurydendroid cell fate. A eurydendroid cell is an efferent neuron found in the cerebellar cortex of teleosts.

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

The regrowth of fin tissue following its loss or destruction.

The orderly movement of a Schwann cell from one site to another. A Schwann cell is a glial cell that ensheathes axons of neuron in the peripheral nervous system and is necessary for their maintainance and function.

The process whose specific outcome is the progression of the enteric nervous system over time, from its formation to the mature structure. The enteric nervous system is composed of two ganglionated neural plexuses in the gut wall which form one of the three major divisions of the autonomic nervous system. The enteric nervous system innervates the gastrointestinal tract, the pancreas, and the gall bladder. It contains sensory neurons, interneurons, and motor neurons. Thus the circuitry can autonomously sense the tension and the chemical environment in the gut and regulate blood vessel tone, motility, secretions, and fluid transport. The system is itself governed by the central nervous system and receives both parasympathetic and sympathetic innervation.

The process in which nerve cells are generated. This includes the production of neuroblasts and their differentiation into neurons.

The process whose specific outcome is the progression of a cardiac neuron over time, from its formation to the mature state.
