What is the structure of an osteoblast?
Osteoblasts are bone-forming cells that have a cuboidal shape with a large, round nucleus. They are responsible for producing and secreting the extracellular matrix of bone, which includes collagen and other proteins. Osteoblasts are also involved in mineralization, where they help deposit calcium and phosphate onto the bone matrix.
Does skull bone grow after brain surgery?
No, skull bone does not regenerate or grow back after brain surgery. However, in some cases, synthetic materials or implants may be used to replace any bone that was removed during the surgery.

How do subarctic peoples make bows?
Subarctic peoples typically make bows using materials such as wood, sinew, and bone. They carve the wood into a bow shape, then attach sinew for the bowstring. Bone or antler may be used for additional reinforcement or decoration. The design and materials used may vary among different subarctic cultures.
What tools were made from buffalo bones?
Buffalo bones were commonly used by Native American tribes to make various tools. This included bone awls for sewing and perforating materials, bone scrapers for removing flesh from hides, bone needles for sewing, bone hammers for pounding, and bone knives for cutting and butchering. The bones were durable and versatile, allowing them to be shaped and sharpened for these purposes.
How to get large bone husk in Monster Hunter 1?
In Monster Hunter, you can obtain Large Bone Husk by hunting and carving certain large monsters, specifically the ones that drop bone materials. Additionally, you can gather them from the Bone Piles found in various areas. Make sure to use a weapon that allows you to carve efficiently and consider bringing items that boost your gathering potential. Prioritize hunting monsters like the Great Jaggi or Barroth, which are known to drop these materials.
What materials did early maori use to make the tools?
