Any process that activates or increases the rate of neuroblast proliferation.

The series of molecular signals initiated by binding of a Wnt protein to a receptor on the surface of the target cell where activated receptors leads to an increase in intracellular calcium and activation of protein kinase C (PKC).

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

Any process that stops, prevents or reduces the rate or extent of progression through the embryonic mitotic cell cycle.

The series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell, followed by propagation of the signal via beta-catenin, and ending with a change in transcription of target genes. In this pathway, the activated receptor signals via downstream effectors that result in the inhibition of beta-catenin phosphorylation, thereby preventing degradation of beta-catenin. Stabilized beta-catenin can then accumulate and travel to the nucleus to trigger changes in transcription of target genes.

The brain is responsible for the coordination and control of bodily activities and the interpretation of information from the senses (sight, hearing, smell, etc.).

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

The process in which the migration of an axon growth cone is directed to a specific target site along the anterior-posterior body axis in response to a combination of attractive and repulsive cues. 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.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an electrical stimulus.

The process in which the migration of an axon growth cone of a commissural neuron is directed to its target in the brain in response to a combination of attractive and repulsive cues.

Coordinated organization of groups of cells in the plane of an epithelium, such that they all orient to similar coordinates.

The characteristic movement of an immature neuron from germinal zones to specific positions where they will reside as they mature.

The last step in the formation of the neural tube, where the paired neural folds are brought together and fuse at the dorsal midline.

The process whose specific outcome is the progression of the hair follicle over time, from its formation to the mature structure. A hair follicle is a tube-like opening in the epidermis where the hair shaft develops and into which the sebaceous glands open.

Any process that activates or increases the rate of neuroblast proliferation.

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

The process whose specific outcome is the progression of the midbrain over time, from its formation to the mature structure. The midbrain is the middle division of the three primary divisions of the developing chordate brain or the corresponding part of the adult brain (in vertebrates, includes a ventral part containing the cerebral peduncles and a dorsal tectum containing the corpora quadrigemina and that surrounds the aqueduct of Sylvius connecting the third and fourth ventricles).

Any process that modulates the frequency, rate or extent of any process in which a protein is transported to, or maintained in, a specific location.

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

The series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell, followed by propagation of the signal via effectors other than beta-catenin.

The process in which a post-anal tail is generated and organized. A post-anal tail is a muscular region of the body that extends posterior to the anus. The post-anal tail may aid locomotion and balance.

The chemotaxis process that directs the migration of an axon growth cone of a dopaminergic neuron to a specific target site in response to a combination of attractive and repulsive cues.

The chemotaxis process that directs the migration of an axon growth cone of a serotonergic neuron to a specific target site in response to a combination of attractive and repulsive cues.

The process in which the anatomical structures of the inner ear are generated and organized. The inner ear is the structure in vertebrates that contains the organs of balance and hearing. It consists of soft hollow sensory structures (the membranous labyrinth) containing fluid (endolymph) surrounded by fluid (perilymph) and encased in a bony cavity (the bony labyrinth). It consists of two chambers, the sacculus and utriculus, from which arise the cochlea and semicircular canals respectively.

Any process that stops, prevents or reduces the rate or extent of progression through the embryonic mitotic cell cycle.

The process in which the anatomical structures of a neuron projection are generated and organized. A neuron projection is any process extending from a neural cell, such as axons or dendrites.

The series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell, followed by propagation of the signal via beta-catenin, and ending with a change in transcription of target genes. In this pathway, the activated receptor signals via downstream effectors that result in the inhibition of beta-catenin phosphorylation, thereby preventing degradation of beta-catenin. Stabilized beta-catenin can then accumulate and travel to the nucleus to trigger changes in transcription of target genes.

The process whose specific outcome is the progression of a sympathetic ganglion over time, from its formation to the mature structure.

Any process that stops, prevents or reduces the frequency, rate or extent of execution phase of apoptosis.

The region of the plasma membrane located at the apical end of the cell.

The portion of the plasma membrane at the lateral side of the cell. In epithelial cells, lateral plasma membranes are on the sides of cells which lie at the interface of adjacent cells.

The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter.

A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.

The end of a filopodium distal to the body of the cell.

The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites.

The region of a polarized cell that forms a tip or is distal to a base. For example, in a polarized epithelial cell, the apical region has an exposed surface and lies opposite to the basal lamina that separates the epithelium from other tissue.
