What is the function of spongy bone in the human body?
Spongy bone, or cancellous bone, supports and protects bone marrow, aids in the production of blood cells, provides structural support, and absorbs shock. It has a porous structure that is lightweight yet strong, making it crucial for weight distribution across joints.
What is the difference between spongy bone and compact bone?
Spongy bone, or cancellous bone, is porous, lighter, and found inside bones, providing structural support and flexibility. Compact bone, or cortical bone, is dense, forms the outer layer of bones, and provides strength and rigidity.
How does the spongy bone contribute to the production of blood cells?
Spongy bone, also known as cancellous bone, contains red bone marrow within its trabecular framework, where hematopoiesis occurs. This process involves the production of red blood cells, white blood cells, and platelets, thus contributing to the body's blood cell supply.
Can spongy bone regenerate after an injury?
Yes, spongy bone, also known as cancellous bone, has the ability to regenerate after an injury. This process involves the activity of osteoblasts, which form new bone tissue, and osteoclasts, which remodel and shape the healed bone. Proper healing requires adequate blood supply and, in some cases, medical intervention.
What disorders or diseases can affect spongy bone?
Disorders and diseases that can affect spongy bone include osteoporosis, osteomalacia, Paget's disease, bone cancer, and certain genetic conditions like osteogenesis imperfecta. These conditions can lead to weakened bone structure, increased fracture risk, and compromised bone functionality.
