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 PDL substance has been estimated to be 70% water, which is thought to have a significant effect on the tooth's ability to withstand stress loads. The completeness and vitality of the PDL are essential for the functioning of the tooth. The PDL ranges in width from 0.15 to 0.38mm with its thinnest part located in the middle third of the root.
[23]: 171 They are found in the walls of large blood vessels and in certain ligaments, particularly in the ligamenta flava. [23]: 173 In hematopoietic and lymphatic tissues, reticular fibers made by reticular cells provide the stroma—or structural support—for the parenchyma (that is, the bulk of functional substance) of the organ.
Cementum [1] is a specialized calcified substance covering the root of a tooth. The cementum is the part of the periodontium that attaches the teeth to the alveolar bone by anchoring the periodontal ligament .
Soft tissue connects and surrounds or supports internal organs and bones, and includes muscle, tendons, ligaments, fat, fibrous tissue, lymph and blood vessels, fasciae, and synovial membranes. [1] [2] Soft tissue is tissue in the body that is not hardened by the processes of ossification or calcification such as bones and teeth. [1] [1]
Dense connective tissue forms strong, rope-like structures such as tendons and ligaments. Tendons attach skeletal muscles to bones ; ligaments connect bones to bones at joints . Ligaments are more stretchy and contain more elastic fibers than tendons.
Cruciate ligaments (also cruciform ligaments) are pairs of ligaments arranged like a letter X. [1] They occur in several joints of the body, such as the knee joint, wrist joint and the atlanto-axial joint. In a fashion similar to the cords in a toy Jacob's ladder, the crossed ligaments stabilize the joint while allowing a very large range of ...
Ligaments bind bone to bone and are similar in structure to tendons. [ 4 ] Aponeuroses are layers of flat, broad tendons that join muscles and the body parts the muscles act upon, whether it be bone or muscle.
