A ligament is the fibrous connective tissue that connects bones to other bones. It also connects flight feathers to bones, in dinosaurs and birds. All 30,000 species of amniotes (land animals with internal bones) have ligaments. It is also known as articular ligament, articular larua, [1] fibrous ligament, or true ligament.
The joint can be considered a synarthrosis. [13] The gomphosis is the only joint-type in which a bone does not join another bone, as teeth are not technically bone. In modern, more anatomical, joint classification, the gomphosis is simply considered a fibrous joint because the tissue linking the structures is ligamentous.
A syndesmosis (“fastened with a band”) is a type of fibrous joint in which two parallel bones are united to each other by fibrous connective tissue. The gap between the bones may be narrow, with the bones joined by ligaments, or the gap may be wide and filled in by a broad sheet of connective tissue called an interosseous membrane. [1]
The connection between a tooth and the jawbone is also called a joint, and is described as a fibrous joint known as a gomphosis. Joints are classified both structurally and functionally. [4] Joints play a vital role in the human body, contributing to movement, stability, and overall function.
The enthesis (plural entheses) is the connective tissue which attaches tendons or ligaments to a bone. [1] There are two types of entheses: fibrous entheses and fibrocartilaginous entheses. [2] [3] In a fibrous enthesis, the collagenous tendon or ligament directly attaches to the bone.
an outer (fibrous membrane, fibrous stratum) composed of avascular white fibrous tissue an inner ( synovial membrane , synovial stratum ) which is a secreting layer On the inside of the capsule, articular cartilage covers the end surfaces of the bones that articulate within that joint.
Each denticulate ligament is composed of a single narrow fibrous strip that extends from the craniovertebral junction to T12. Each ligament features 18-20 triangular extensions that attach to the dura at their apices [ citation needed ] in between successive nerve roots . [ 1 ]
The fibrous pericardium is attached to the posterior surface of the sternum by the superior and inferior sternopericardiac ligaments (sternopericardial ligaments); the upper passing to the manubrium, and the lower to the xiphoid process.
