What is the function of the endosteum?
Endosteum is a soft, thin connective tissue that lines the inner cavity of long bones. It plays an important role in the healing of fractures by creating new cells necessary for the bone to fuse. This connective tissue also has hematopoietic potencies, which means that it contains haematopoietic stem cells (HSCs).
What is the difference between periosteum and endosteum?
The key difference between periosteum and endosteum is that the periosteum consists of an outer fibrous connective tissue layer and an inner osteogenic layer while the endosteum is the thin membranous coating that covers the internal surface of the bone. Bones play an important role in anatomy and physiology.
What is the difference between periosteum and endosteum in terms of where they are found and what they are made of?
Figure 6.32 – Periosteum and Endosteum: The periosteum forms the outer surface of bone, and the endosteum lines the medullary cavity. Flat bones, like those of the cranium, consist of a layer of diploë (spongy bone), covered on either side by a layer of compact bone (Figure 6.3. 3).
What is the function of the endosteum quizlet?
The endosteum an incomplete cellular layer, lines the marrow cavity. This layer which is active during bone growth, repair, and remodeling, covers the trabeculae of spongy bone and lines the inner surfaces of the central canals.
What is an endosteum periosteum?
Endosteum covers the inside of bones, and surrounds the medullary cavity. The outer surface of a bone is lined by a thin layer of connective tissue that is very similar in morphology and function to endosteum. It is called the periosteum, or the periosteal surface.
What does endosteum mean?
Endosteum: A membrane lining the inner surface of the bony wall also identified as the lining membrane of the Bone marrow cavity is endosteum; The endosteum lines the Haversian canal and all the internal cavities of the bone.
What cells are in the endosteum?
The endosteum is lined by a single thin layer of bone-lining cells (mature osteoblasts) and osteoblasts which form a membrane over endocortical and trabecular bone surfaces to enclose the bone marrow [34]. Osteoclasts can also be present in the endosteum in regions of active bone resorption.
