The process in which the anatomical structures of epithelia are generated and organized. An epithelium consists of closely packed cells arranged in one or more layers, that covers the outer surfaces of the body or lines any internal cavity or tube.

Any cellular process that results in the specification, formation or maintenance of anisotropic intracellular organization or cell growth patterns.

The process whose specific outcome is the progression of the gonad over time, from its formation to the mature structure. The gonad is an animal organ that produces gametes; in some species it also produces hormones.

Any process that modulates the frequency, rate or extent of asymmetric cell division.

Any process that modulates the frequency, rate or extent of asymmetric cell division.

Any process resulting in the establishment of polarity along the anterior/posterior axis.

Any process resulting in the establishment of polarity along the anterior/posterior axis.

Any process resulting in the establishment of polarity along the proximal/distal axis.

Any process resulting in the establishment of polarity along the proximal/distal axis.

Any process that modulates the frequency, rate or extent of cell migration.

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.

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 modulates the frequency, rate or extent of development of the vulva. Vulval development is the process whose specific outcome is the progression of the egg-laying organ of female and hermaphrodite nematodes over time, from its formation to the mature structure. In nematodes, the vulva is formed from ventral epidermal cells during larval stages to give rise to a fully formed vulva in the adult.

The process whose specific outcome is the progression of the hermaphrodite genitalia over time, from formation to the mature structures.

The process whose specific outcome is the progression of the hermaphrodite genitalia over time, from formation to the mature structures.

Any process that mediates the adoption of a specific fate by a cell.

The process in which the anatomical structure of the adult male tail tip is generated and organized. In some species of rhabitid nematodes, the male tail tip undergoes a morphological change such that the most posterior hypodermal cells in the tail (hyp8-11 in C. elegans) fuse and retract anteriorly, changing the shape of the tail from a pointed, tapered cone, or spike, to a rounded, blunt dome.

Any process in which a protein is transported to, or maintained in, a specific asymmetric distribution, resulting in the formation of daughter cells of different types.

Any process in which a protein is transported to, or maintained in, a specific asymmetric distribution, resulting in the formation of daughter cells of different types.

The process that determines the orientation of an anatomical structure with reference to an axis.

The process that determines the orientation of an anatomical structure with reference to an axis.

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 in which the migration of an axon growth cone of an interneuron is directed to a specific target site in response to a combination of attractive and repulsive cues. An interneuron is any neuron which is not motor or sensory. Interneurons may also refer to neurons whose axons remain within a particular brain region, as contrasted with projection neurons which have axons projecting to other brain regions.

The orderly movement of a neuroblast from one site to another, often during the development of a multicellular organism or multicellular structure. A neuroblast is any cell that will divide and give rise to a neuron.

The orderly movement of a neuroblast from one site to another, often during the development of a multicellular organism or multicellular structure. A neuroblast is any cell that will divide and give rise to a neuron.

The orderly movement of a motor neuron from one site to another. A motor neuron is an efferent neuron that passes from the central nervous system or a ganglion toward or to a muscle and conducts an impulse that causes movement.

The orderly movement of an interneuron from one site to another.

Any process that activates or increases the frequency, rate or extent of motor neuron migration.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The portion of the plasma membrane surrounding a neuron projection.
