Final answer:
The healing time for broken bones involves the formation of a fracture hematoma followed by the intrusion of capillaries and phagocytic cells. A fibrocartilaginous callus eventually converts to a bony callus, a process taking about two months, with bone remodeling extending over several months.
Step-by-step explanation:
The question relates to the healing process and timeline of different tissues in the human body, specifically muscles, tendons, ligaments, and bones. While the original prompt does not provide specific healing times for muscles, tendons, and ligaments, it does describe bone repair in detail. Initially, blood flow from torn vessels results in a fracture hematoma, which is clotted blood at the fracture site. This disruption causes bone cell death around the fracture area. Then, within days, capillaries and phagocytic cells intrude, clearing dead cells and helping form a fibrocartilaginous callus with the help of fibroblasts and osteoblasts.
Bone healing progresses as the callus is converted into a bony callus of spongy bone, which usually takes about two months to firmly join the broken bone ends. Finally, bone remodeling, which can take many months, occurs as osteoclasts and osteoblasts reshape the bone back to its original form.
