  3. Axoneme - Wikipedia

    en.wikipedia.org/wiki/Axoneme

    Inside a cilium and a flagellum is a microtubule-based cytoskeleton called the axoneme. The axoneme of a primary cilium typically has a ring of nine outer microtubule doublets (called a 9+0 axoneme), and the axoneme of a motile cilium has two central microtubules in addition to the nine outer doublets (called a 9+2 axoneme).

  4. Antenna (zoology) - Wikipedia

    en.wikipedia.org/wiki/Antenna_(zoology)

    The three basic segments of the typical insect antenna are the scape or scapus (base), the pedicel or pedicellus (stem), and finally the flagellum, which often comprises many units known as flagellomeres. [10] The pedicel (the second segment) contains the Johnston's organ which is a collection of sensory cells. [11]

  5. Bacterial motility - Wikipedia

    en.wikipedia.org/wiki/Bacterial_motility

    The bacterial flagellum is a protein-nanomachine that converts electrochemical energy in the form of a gradient of H+ or Na+ ions into mechanical work. [26] [27] [28] The flagellum is composed of three parts: the basal body, the hook, and the filament. The basal body is a reversible motor that spans the bacterial cell envelope.

  6. Basal body - Wikipedia

    en.wikipedia.org/wiki/Basal_body

    Schematic of the eukaryotic flagellum. 1-axoneme, 2-cell membrane, 3-IFT (Intraflagellar transport), 4-Basal body, 5-Cross section of flagellum, 6-Triplets of microtubules of basal body. Longitudinal section through the flagella area in Chlamydomonas reinhardtii. In the cell apex is the basal body that is the anchoring site for a flagellum.

  7. Flagellate - Wikipedia

    en.wikipedia.org/wiki/Flagellate

    Flagella in eukaryotes are supported by microtubules in a characteristic arrangement, with nine fused pairs surrounding two central singlets. These arise from a basal body. In some flagellates, flagella direct food into a cytostome or mouth, where food is ingested. Flagella role in classifying eukaryotes.

  8. Cell (biology) - Wikipedia

    en.wikipedia.org/wiki/Cell_(biology)

    Flagella are organelles for cellular mobility. The bacterial flagellum stretches from cytoplasm through the cell membrane(s) and extrudes through the cell wall. They are long and thick thread-like appendages, protein in nature. A different type of flagellum is found in archaea and a different type is found in eukaryotes.

  9. Sperm - Wikipedia

    en.wikipedia.org/wiki/Sperm

    The sperm tail is a specialized type of cilium (aka flagella). In many animals the sperm tail is formed through the unique process of cytosolic ciliogenesis, in which all or part of the sperm tail's axoneme is formed in the cytoplasm or gets exposed to the cytoplasm. [40]
