A joint or articulation (or articular surface) is the connection made between bones, ossicles, or other hard structures in the body which link an animal's skeletal system into a functional whole.
Articulate brachiopods have an outermost periostracum made of proteins, a "primary layer" of calcite (a form of calcium carbonate) under that, and innermost a mixture of proteins and calcite. [9] Inarticulate brachiopod shells have a similar sequence of layers, but their composition is different from that of articulated brachiopods and also ...
The articular process or zygapophysis (Greek: ζυγόν, romanized: zugón, lit. 'yoke' + apophysis) of a vertebra is a projection of the vertebra that serves the purpose of fitting with an adjacent vertebra.
Articulation (anatomy), the location at which two or more bones make contact Articulation (architecture), in art and architecture, is a method of styling the joints in the formal elements of architectural design
In human anatomy, the main role of the carpal bones is to articulate with the radial and ulnar heads to form a highly mobile condyloid joint (i.e. wrist joint), [1] to provide attachments for thenar and hypothenar muscles, and to form part of the rigid carpal tunnel which allows the median nerve and tendons of the anterior forearm muscles to be ...
Articulate brachiopods, brachiopods with toothed hinges and simple opening and closing muscles; Articulate sound, to move the tongue, lips, or other speech organs in order to make speech sounds; Articulated vehicle, a vehicle which has a pivoting joint in its construction; Articulate, a public television series about creative artists
The jumping spider Phidippus audax.The basal parts of the chelicerae are the two iridescent green mouthparts. The chelicerae (/ k ə ˈ l ɪ s ər iː /) are the mouthparts of the subphylum Chelicerata, an arthropod group that includes arachnids, horseshoe crabs, and sea spiders.
The stalk (or pedicle) is a long white extension of the body, that emerges at the apex from between the valves, and not, as in articulate brachiopods, from a special opening in the dorsal valve. At the rear end, that is deepest in the sea bed, the skin (or epithelium ) secretes a glue-like mucus that binds to the substrate's particles, thus ...
