Periostium and endostium
Yes, osteoblasts from the medullary cavity can migrate to the fracture site to participate in bone healing. When a bone fractures, osteoblasts are recruited from various sources, including the medullary cavity, to produce new bone tissue and facilitate the repair process.
No, but you can bear weight on a fracture! It does, however. depend on how long ago the fracture occurred and how severe the damage is.
A single fracture means that one fracture only has occurred and multiple fractures refer to more than one fracture occurring in the same bone
FRACTURE.
No, osteocytes don't mature into osteoblasts. Osteoblasts mature into osteocytes.
Osteoblasts mature into osteocytes.
Osteoprogenitor cells differentiate into osteoblasts. Osteoblasts develop osteocytes.
The pathophysiology of a forearm fracture involves the disruption of bone integrity due to an excessive force, which can be classified as either a traumatic or pathological fracture. When the force exceeds the bone's tensile or compressive strength, it results in a break, causing pain, swelling, and loss of function. The fracture triggers a biological response, leading to inflammation and the formation of a hematoma at the fracture site, followed by the activation of osteoblasts and chondroblasts for bone healing. Over time, the fracture site undergoes remodeling as the bone heals and returns to its original strength.
Osteoblasts
Osteoclasts (Osteo - bone, clast - make or create)
Osteoblasts are needed to create bone. Osteoclasts destroy bone.
When a bone breaks, the body initiates a process called bone remodeling. Osteoclasts are cells that break down and remove the damaged bone tissue, while osteoblasts come in to build new bone tissue to repair the fracture. This process helps to remodel and strengthen the bone at the site of the break.
