|---|---|---|---|
| GO:0005615 | extracellular space | That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid. | 522 |
| GO:0048046 | apoplast | The cell membranes and intracellular regions in a plant are connected through plasmodesmata, and plants may be described as having two major compartments: the living symplast and the non-living apoplast. The apoplast is external to the plasma membrane and includes cell walls, intercellular spaces and the lumen of dead structures such as xylem vessels. Water and solutes pass freely through it. | 192 |
| GO:0070062 | extracellular vesicular exosome | A membrane-bounded vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. | 118 |
| GO:0044421 | extracellular region part | Any constituent part of the extracellular region, 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 constituent parts of the host cell environment outside an intracellular parasite. | 47 |
| GO:0005578 | proteinaceous extracellular matrix | A layer consisting mainly of proteins (especially collagen) and glycosaminoglycans (mostly as proteoglycans) that forms a sheet underlying or overlying cells such as endothelial and epithelial cells. The proteins are secreted by cells in the vicinity. An example of this component is found in Mus musculus. | 34 |
| GO:0045171 | intercellular bridge | A direct link between the cytoplasms of sister cells that allows cells to communicate with one another. Germline intercellular bridges facilitate the passage of cytoplasmic components between cells during development. Intercellular bridges have also been found connecting somatic cells. | 15 |
| GO:0045172 | germline ring canal | Germline specific intercellular bridge. During cyst formation in insects, ring canals interconnect the cells of the cyst, facilitating the passage of cytoplasmic components between cells. | 12 |
| GO:0035324 | female germline ring canal | An intercellular bridge that connects the germline cells of a female cyst. | 3 |
| GO:0035183 | female germline ring canal inner rim | A proteinaceous actin-rich layer of the insect ovarian ring canal that forms subcortically to the outer rim. The electron dense inner rim accumulates after the final mitotic division of each germline syncytia, and contains actin, a phosphotyrosine protein, and a number of cytoskeletal proteins. | 2 |
| GO:0044231 | host cell presynaptic membrane | A specialized area of membrane of the host axon terminal that faces the plasma membrane of the host neuron or muscle fiber with which the axon terminal establishes a synaptic junction; many host synaptic junctions exhibit structural presynaptic characteristics, such as conical, electron-dense internal protrusions, that distinguish it from the remainder of the axon plasma membrane. | 2 |
| GO:0020005 | symbiont-containing vacuole membrane | The lipid bilayer surrounding a symbiont-containing vacuole, derived from both the host and symbiont. | 2 |
| GO:0035182 | female germline ring canal outer rim | An electron opaque backbone of the insect ovarian ring canal that is a part of or adjacent to the plasma membrane. The outer rim is established as the cleavage furrow is arrested, and contains F-actin, anillin, glycoproteins and at least one a protein with a high content of phosphorylated tyrosine residues. | 1 |
| GO:0020002 | host cell plasma membrane | The plasma membrane surrounding a host cell. | 1 |
