A joint, or articulation is the region where adjacent bones contact each other, for example the elbow, shoulder, or costovertebral joint. Terms that refer to joints include: articular process, referring to a projection that contacts an adjacent bone. suture, referring to an articulation between cranial bones.
Human vocal tract Articulation visualized by real-time MRI. In articulatory phonetics, the manner of articulation is the configuration and interaction of the articulators (speech organs such as the tongue, lips, and palate) when making a speech sound. One parameter of manner is stricture, that is, how closely the speech organs approach one another.
The term dysarthria was formed from the Greek components dys-"dysfunctional, impaired" and arthr-"joint, vocal articulation". [5] [6] Neurological injury due to damage in the central or peripheral nervous system may result in weakness, paralysis, or a lack of coordination of the motor–speech system, producing dysarthria.

Articulation (botany), a joint between two separable parts, as a leaf and a stem; see Glossary of botanical terms; Articulation (dentistry), the contact relationship of the occlusal surfaces of the upper and lower teeth when moving into and away from centric occlusion
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. [ 1 ] [ 2 ] [ 3 ] They are constructed to allow for different degrees and types of movement.
The point of maximum obstruction is called the place of articulation, and the way the obstruction forms and releases is the manner of articulation. For example, when making a p sound, the lips come together tightly, blocking the air momentarily and causing a buildup of air pressure. The lips then release suddenly, causing a burst of sound.
Articulations of pelvis. Anterior view. Articulations of pelvis. Posterior view. Sacroiliac joints are paired C-shaped or L-shaped joints capable of a small amount of movement [2] (2–18 degrees, which is debatable at this time) that are formed between the auricular surfaces of the sacrum and the ilium bones.
The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower ...
