Typically, each body segment carries one pair of appendages. An appendage which is modified to assist in feeding is known as a maxilliped or gnathopod. [citation needed] In annelids lateral protrusions from the body are called parapodia. In echinoderms an appendage called a pedicellaria is found. The end of the pedicellaria consists of valves ...
Other cellular extensions that protrude from the cell membrane are known as membrane protrusions or cell protrusions, also cell appendages, such as flagella, and microvilli. [ 8 ] [ 9 ] Microtentacles are cell protrusions attached to free-floating cells, associated with the spread of some cancer cells .
Skin appendages (or adnexa of skin) are anatomical skin-associated structures that serve a particular function including sensation, contractility, ...
By this definition the eight appendages of octopuses, though quite long, count as arms. [2] While arms are distinct from tentacles (a definition specific to the limb featuring peduncles), arms do fall within the general definition of "tentacle" as "a flexible, mobile, and elongated organ" and "tentacle" could be used as an umbrella term .
A flagellum (/ f l ə ˈ dʒ ɛ l əm /; pl.: flagella) (Latin for 'whip' or 'scourge') is a hair-like appendage that protrudes from certain plant and animal sperm cells, from fungal spores (), and from a wide range of microorganisms to provide motility.
In biology, a tagma (Greek: τάγμα, pl.: tagmata – τάγματα - body of soldiers; battalion) is a specialized grouping of multiple segments or metameres into a coherently functional morphological unit. Familiar examples are the head, the thorax, and the abdomen of insects. [1]
To create the pseudopod, the gel of the ectoplasm begins to convert to sol which, along with the endoplasm, pushes a portion of the plasma membrane into an appendage. Once the pseudopod is extended, the sol within begins to peripherally convert back to gel, converting back to the ectoplasm as the lagging cell body flows up into the pseudopod ...
Apophysis (plural apophyses): An outgrowth or process changing the general shape of a body part, particularly the appendages; often used in describing the male pedipalp: [2] see retrolateral tibial apophysis; Atrium (plural atria): An internal chamber at the entrance to the copulation duct in female haplogyne spiders [2]
