A specialized eukaryotic organelle that consists of a filiform extrusion of the cell surface. Each cilium is bounded by an extrusion of the cytoplasmic membrane, and contains a regular longitudinal array of microtubules, anchored basally in a centriole. A 9+0 cilium that forms the portion of the axoneme traversing the boundary between the photoreceptor inner and outer segments. An immotile primary cilium that may be missing the central pair of microtubules, or the central pair of microtubules and outer dynein arms. Some primary cilia also have altered arrangements of outer microtubules (fewer than nine and/or not always present as doublets). Nonmotile primary cilia typically function as sensory organelles that concentrate and organize sensory signaling molecules.
