What is an example of articulation?
Symptoms of Articulation and Phonological Disorders Examples of articulation errors include substituting one sound for another (e.g., saying wed for red), or leaving out sounds (e.g., nana instead of banana). Another type of articulation disorder is distortion of the “s” sound, also known as a lisp.

Where do Symphyses occur?
A symphysis (fibrocartilaginous joint) is a joint in which the body (physis) of one bone meets the body of another. All but two of the symphyses lie in the vertebral (spinal) column, and all but one contain fibrocartilage as a constituent tissue.
What is a joint capsule?
The joint capsule resembles a sac-like envelope that forms a sleeve around the synovial joint and encloses its cavity. The joint capsule is a dense fibrous connective tissue that is attached to the bones via specialized attachment zones at the end of each involved bone.

What type of joint are sutures?
In fibrous joints the articulating parts are separated by white connective tissue (collagen) fibres, which pass from one part to the other. There are two types of fibrous joints: suture and gomphosis. A suture is formed by the fibrous covering, or periosteum, of two bones passing between them.
