How Do You Spell PROVISIONAL CALLUS?

1. A provisional callus refers to a temporary protective layer of tissue that forms around a broken or injured bone during the initial stages of the healing process. When a bone breaks, the body activates several physiological mechanisms to repair the fracture. One of these processes involves the formation of a provisional callus as an initial response to stabilize the injured area.

   The provisional callus is comprised of new connective tissue cells, primarily collagen, which are produced by specialized cells called fibroblasts. This callus acts as a protective layer covering the fracture site and serves as a scaffold or framework for the subsequent stages of bone healing. It helps to immobilize and support the broken bone, preventing further damage and allowing for the subsequent formation of a more solid callus.

   The provisional callus is characterized by its temporary nature as it is gradually replaced by a tougher and more permanent callus. This process occurs through a series of subsequent events, such as the recruitment of osteoblasts (cells responsible for bone formation) that deposit new mineralized bone tissue within the provisional callus. Eventually, this provisional callus is remodeled and transformed into mature bone, completing the healing process.

   In summary, a provisional callus is an initial protective tissue formation that occurs around a fractured bone, providing stability, protection, and a foundation for the subsequent stages of bone healing.

2. • The c. thrown out as nature's splint to keep the ends of the bone in apposition; it is absorbed after union is complete.

   • The callus formed around a bone, and sometimes in the medullary cavity, after a fracture, which is absorbed after union has occurred.

Common Misspellings for PROVISIONAL CALLUS

The term "provisional callus" does not have its own specific etymology, as it is made up of two separate words: "provisional" and "callus".

"Provisional" comes from the Latin word "provisio", which means "a foreseeing, foresight, preparation" or "a providing, provision". In English, "provisional" refers to something that is temporary, conditional, or subject to change.

"Callus" comes from the Latin word "callus", which means "hard skin" or "thickening of the skin". In biological terms, a callus refers to a thickened and hardened part of the skin that develops in response to repeated friction, pressure, or irritation.

Therefore, when combined, "provisional callus" refers to a temporary or transient hardening or thickening of the skin.
