When a bone is fractured, a callus forms as the fracture heals. This tissue ossifies over time and provides full restoration of function and stability. However, under certain conditions, fracture healing may be pathologic and may involve various complications. What is the callus? The term callus is derived from the Latin word callus (“callus,” “thick … Callus: Structure, Function & Diseases
Callus hardening is the fourth phase of the five-phase secondary fracture healing process. Osteoblasts form a callus of connective tissue to bridge fracture gaps, which they mineralize with calcium to harden it. In fracture healing disorders, this process is impaired and the bone lacks stability. What is callus hardening? Callus hardening is the fourth phase … Callus Hardening: Function, Tasks, Role & Diseases
In mineralization, minerals are deposited in hard tissues, such as the teeth or bones, for hardening. In the body, there is a permanent balance between mineralization and demineralization. In the case of a mineral deficiency or other mineralization disorders, this balance is disturbed. What is mineralization? In mineralization, minerals are deposited in hard tissues, such … Mineralization: Function, Tasks, Role & Diseases
Desmal ossification involves the conversion of embryonic connective tissue into bone. In comparison to chondral ossification, direct bone formation takes place here. In particular, the skull, facial skull, and clavicle are formed via desmal ossification. What is desmal ossification? During desmal ossification, embryonic connective tissue is transformed into bone. Figure shows embryo with recognizable spine. … Desmal Ossification: Function, Tasks, Role & Diseases
The remodeling phase is the final phase of the five-phase secondary fracture healing process. During this phase, old bone mass is removed and new bone substance is built up through the simultaneous activity of osteoclasts and osteoblasts. In osteoporosis, the activity of osteoblasts and osteoclasts is impaired. What is the remodeling phase? The remodeling phase … Remodeling Phase: Function, Tasks, Role & Diseases
The injury phase is the first and shortest phase of secondary fracture healing. It overlaps with the second phase, the inflammatory phase. During the injury phase, fracture fragments can injure internal organs in extreme cases. What is the injury phase? The injury phase is the first and shortest phase of secondary fracture healing. A fracture … Injury Phase: Function, Tasks, Role & Diseases
Bone tissue remodeling corresponds to bone remodeling that occurs permanently within bone tissue. Bones are adapted to current loading conditions by the remodeling processes of osteoclasts and osteoblasts. Excessive bone remodeling characterizes Paget’s disease. What is bone tissue remodeling? Bone tissue remodeling corresponds to bone remodeling that occurs permanently within bone tissue. Bone tissue damage … Bone Tissue Remodeling (Bone Remodeling): Function, Tasks, Role & Diseases
Fracture healing is the healing of a bone fracture. A distinction is made between primary and secondary fracture healing. Disruption of this process can lead to pseudarthrosis. What is fracture healing? Fracture healing is the healing of a bone fracture. The healing process after a bone defect is called fracture healing. There are two types … Fracture Healing: Function, Tasks, Role & Diseases
What is the function of the periosteum? The function of the outer cell layer, the stratum fibrosum, is closely related to the position and course of the collagen fibers or Sharpey fibers. These fibers have a high tensile strength and also exhibit a certain elasticity. Since the Sharpey fibers pass through the inner cell layer … What is the function of the periosteum? | The periosteum
Which diseases of the periosteum are there? An inflammation of the periosteum is also called periostitis. Since the periosteum is interspersed with numerous nerve fibers, an inflammation often causes severe pain. This occurs particularly frequently in the area of the tibia. In addition, there is a strong swelling due to increased fluid content. However, this … Which diseases of the periosteum are there? | The periosteum
What does pain through the periosteum indicate? The stratum osteogenicum of the periosteum has a high proportion of nerves. Since the bone itself has no nerve fiber, the periosteum indirectly assumes an important function in the perception of pain in the bone.Pain, which is passed on through the nerve fibres of the periosteum, can have … What does pain through the periosteum indicate? | The periosteum
What is bone skin cancer? Bone skin cancer develops when the cells that form bone substance degenerate and is called osteosarcoma. These original cells are called osteoblasts and are found in the periosteum, among other areas. However, the same type of cancer can also develop within the bone. This type of cancer is characterized by … What is bone skin cancer? | The periosteum
