Examples of appendage in the following topics:

  • Orbits

    • The orbit is the cavity or socket of the skull in which the eye and its appendages are situated.
    • The orbit, or eye socket, is the cavity located in the skull in which the eye and its associated appendages are housed.

  • Adherence

    • Adhesins are cell-surface components or appendages of bacteria that facilitate bacterial adhesion to other cells or to inanimate surfaces.
    • Adhesins are cell-surface components or appendages of bacteria that facilitate bacterial adhesion or adherence to other cells or to inanimate surfaces.
    • In bacteriology, a fimbria (plural fimbriae; abbreviated FIM) is an appendage composed of curlin proteins that can be found on many Gram-negative and some Gram-positive bacteria that is thinner and shorter than a flagellum.
    • This appendage ranges from 3-10 nanometers in diameter and can be up to several micrometers long.

  • Directional Terms

    • These are mostly used with animal anatomy, but can be used in human anatomy as long as they are describing the side of an appendage.
    • For example, bones in an appendage are located deeper than the muscles.
    • When describing appendages, the proximal end of the appendage connects the appendage to the body, while the distal end is away from the body.

  • Overview of the Appendicular Skeleton

    • The unfused appendicular skeleton is composed of the appendages (legs and arms) and their supporting girdles, totaling 126 bones.
    • The word "appendicular" comes from "appendage," which means "a part that is joined to something larger. " The appendicular skeleton comprises the limbs and their supporting girdles (pectoral and pelvic).

  • Anatomical Position

    • All descriptions refer to the organism in its standard anatomical position, even when the organism's appendages are in another position.
    • The positions of the limbs, particularly the arms, have important implications for directional terms in those appendages.

  • Subphyla of Arthropoda

    • Crustaceans possess two pairs of antennae, mandibles as mouthparts, and biramous ("two branched") appendages: their legs are formed in two parts, as distinct from the uniramous ("one branched") myriapods and hexapods.
    • The phylum derives its name from the first pair of appendages, the chelicerae, which are specialized claw-like or fang-like mouthparts.
    • The second pair of appendages is known as pedipalps.
    • In some species, such as sea spiders, an additional pair of appendages, called ovigers, is present between the chelicerae and pedipalps.

  • Morphologically Unusual Proteobacteria

    • Prosthecate bacteria are a non-phylogenetically related group of Gram-negative bacteria that possess appendages, termed prosthecae.
    • These cellular appendages are neither pili nor flagella, as they are extensions of the cellular membrane and contain cytosol.

  • Agnathans: Jawless Fishes

    • A defining feature of agnathans is the lack of paired lateral appendages or fins.
    • Lampreys are morphologically similar to hagfishes and also lack paired appendages.

  • Deep Wound Healing

    • If the basement membrane is ruined at the wound site (deep wound), reepithelization must occur from the wound margins and from skin appendages, such as hair follicles and sweat and oil glands that enter the dermis and are lined with viable keratinocytes.
    • If the wound is very deep, skin appendages may also be ruined, and migration can only occur from wound edges.

  • Regional Terms and Axes

    • This includes the limbs and appendages.
    • Any pair of corresponding directional terms can be combined to form an axis (such as proximal-distal for an appendage).
