The formation of a syncytium, a mass of cytoplasm containing several nuclei enclosed within a single plasma membrane, by the fusion of the plasma membranes of two or more individual cells.

The formation of a syncytium, a mass of cytoplasm containing several nuclei enclosed within a single plasma membrane, by the fusion of the plasma membranes of two or more individual cells.

The formation of a syncytium, a mass of cytoplasm containing several nuclei enclosed within a single plasma membrane, by the fusion of the plasma membranes of two or more individual cells.

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.

The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult).

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

The deposition of eggs (either fertilized or not) upon a surface or into a medium such as water.

Self-propelled movement of a cell or organism from one location to another.

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 in which the anatomical structures of the post-embryonic soma are generated and organized.

The process whose specific outcome is the progression of the pharyngeal muscle over time, from its formation to the mature structure. A pharyngeal muscle is any muscle that forms part of the pharynx.

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.

The process in which the anatomical structures of the nematode male tail mating organ are generated and organized. The male tail is a sensory organ required for mating and, in C. elegans, consists of ray sensilla, an acellular cuticular fan, a sensory hook, and protracting, copulatory spicules.

A cellular process in which two or more cells combine together, their plasma membrane fusing, producing a single cell. In some cases, nuclei fuse, producing a polyploid cell, while in other cases, nuclei remain separate, producing a syncytium.

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

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

Extended zone of intimate apposition between two cells containing one or more types of intercellular junctions, e.g., the intercalated disk of muscle.
