Woven Bone Vs. Lamellar Bone | Key Differences Explained
Weaving bone, also known as immature bone, has a random, weaving arrangement of collagen fibres, making it weaker but more flexible. In contrast, lamellar bone has a well-organized, layered (lamellar) collagen structure, which results in higher strength and stiffness.

2019年6月5日 · They are then not as tightly packed and found in somewhat randomly oriented bundles: this type of bone is called woven bone, as opposed to lamellar bone. Woven bone is characterized by irregular bundles of collagen fibers, large and numerous osteocytes, and delayed, disorderly calcification which occurs in irregularly distributed patches.

2023年11月30日 · Answer C is incorrect because woven bone has a higher mineral content than lamellar bone. Answer B is incorrect because woven bone is more hypercellular than lamellar bone. Answer D is incorrect because woven bone is fabricated during rapid bone formation.

Woven bone is characterized by the irregular organization of collagen fibers and is mechanically weak, but forms quickly. Lamellar bone is much stronger than woven bone, and is highly organized in concentric sheets with a much lower proportion of osteocytes to mineralized tissue.

2024年9月5日 · Woven bone (primary bone) – Appears in embryonic development and fracture repair, as it can be laid down rapidly. It consists of osteoid (unmineralised ECM), with the collagen fibres arranged randomly. It is a temporary structure, soon replaced by mature lamellar bone. Lamellar bone (secondary bone) – The bone of the adult skeleton. It ...

Short bones include the carpal and tarsal bones, patellae, and sesamoid bones. Flat bones include the skull, mandible, scapulae, sternum, and ribs. Irregular bones include the vertebrae, sacrum, coccyx, and hyoid bone.
Over time, bone cells remodel the woven bone into a more organized form – lamellar bone. Lamellar bone contains osteons, also known as Haversian systems (Figure 1).

The first type of bone formed developmentally is primary or woven bone (immature). This immature bone is later replaced by secondary or lamellar bone (mature). Secondary bone is further classified as two types: trabecular bone (also called cancellous or spongy bone) and compact bone (also called dense or cortical bone).
Introduction to Bone – Boundless Anatomy and Physiology
There are two types of bone tissue: cortical and cancellous bone. Cortical bone is compact bone, while cancellous bone is trabecular and spongy bone. Cortical bone forms the extremely hard exterior while cancellous bone fills the interior. The tissues are biologically identical but differ in the arrangement of their microstructure.
