Question

Sharpey fibers occur inside
A)Collagen
B)muscle
C)Bone
D)Skin

Answer 1

It is a connective tissue that is made of minerals and exhibits four types of cells known as osteoblasts, bone lining cells, osteocytes, and osteoclasts. Many important functions are performed by including the locomotion of the body, support of the body and protection of soft tissues, storage of calcium and phosphate, and harboring of bone marrow.

Complete step by step answer:
-A matrix of connective tissue composed of bundles of strong predominantly type I collagen fibers which connect the periosteum to the bone is known as Sharpey’s fibers (bone fibers, or perforating fibers).
-It consists of the outer fibrous layer of periosteum which enters into the outer circumferential and interstitial lamellae of bone tissue.
-Attachment of muscles to the periosteum of bone is carried by Sharpey fibers by merging with both fibrous periosteum and underlying bone. The attachment of the rotator cuff muscles to the plates of the scapula is a very good example of Sharpey fibers.
-The extreme end of the principal fibers of the periodontal ligament are the Sharpey fibers existing in the teeth that inlay into the cementum and within the periosteum of the alveolar bone.

So, the correct answer is,” bone”.

Additional information: Collagen - the most abundant proteins found in the human body is collagen. It is also present in the bones, muscles, skins, and tendons. It holds a body together and forms a scaffold to provide strength and structure.
Muscle - In most animals, it is present as soft tissue. The protein filaments of actin and myosin are present in the muscle cells that are slightly passed from one another that changes both the length and shape of the cell. It has been producing force and motion.
Skin - About 20 square feet of the total area of the body is covered by the skin. It protects from the harmful microorganisms and health in regulating the temperature of the body and permits the sensation of touch, heat, and cold.

Note:
-A bundles of strong predominantly type 1 collagen fibers present in the matrix of connective tissue that connects the periosteum to the bone known as Sharpey's fibers or bone fibers.
-Periosteum is a dense layer of vascular connective tissue covering the bones except at the surface of the joints.
-From the fibrous layer into the bone matrix, the dense tuft of collagen fibers are extended included in the Sharpey's fibers.
-In the tooth and porous Sharpey's fibers are a very known skeleton.
