What is the function of Sharpey fibers?
In the skull the main function of Sharpey’s fibres is to bind the cranial bones in a firm but moveable manner; they are most numerous in areas where the bones are subjected to the greatest forces of separation. In the spine, similar fibres join the intervertebral disc to the adjacent vertebrae.
Which of the following is the function of Sharpey’s fibers in a long bone?
They are part of the outer fibrous layer of periosteum, entering into the outer circumferential and interstitial lamellae of bone tissue. Sharpey’s fibres are also used to attach muscle to the periosteum of bone by merging with the fibrous periosteum and underlying bone as well.

What are perforating fibers?
n. Any of the bundles of collagen fibers that pass into the outer circumferential lamellae of bone or into the cementum of teeth.
What is the function of periodontal ligament?
The PDL is a highly specialized connective tissue situated between the tooth and the alveolar bone (Figure 1-5). The principal function of the PDL is to connect the tooth to the jaw, which it must do in such a way that the tooth will withstand the considerable forces of mastication.
What are principal fibers?
Alveolodental ligament. The main principal fiber group is the alveolodental ligament, which consists of five fiber subgroups: alveolar crest, horizontal, oblique, apical, and interradicular on multirooted teeth. Principal fibers other than the alveolodental ligament are the transseptal fibers.
What is the purpose of central canal in osteons?
At the center of each osteon is a central canal (also known as a Haversian canal) through which blood vessels, lymph vessels, and nerves can travel to service and signal the cells throughout the compact bone.
What is the function of interstitial lamellae?
The space between osteons is occupied by interstitial lamellae, which are the remnants of osteons that were partially resorbed during the process of bone remodeling. Osteons are connected to each other and the periosteum by oblique channels called Volkmann’s canals or perforating canals.
What is the most important physical function of periodontal ligament?
The PDL protects the blood vessels and nerves from injury by mechanical forces. It also attaches the tooth to the bone in the socket, and the absorption of occlusal forces protects the vessels, nerves and bone from injury . A primary role of the ligament is to act as a medium of force transfer during mastication.
What are the functions of the periodontal ligaments quizlet?
14- Periodontal ligament. Functions: help tooth withstand the compressive forces during chewing and remain embedded in the alveolar bone; serves as a source of proprioception, or sensory innervation, so the brain can detect the forces being placed on the teeth. You just studied 24 terms!
