Okay, heres one of those questions that isn't easily found in lab manuals and text books (atleast mine).
ALSO, if you have a source, could you please show me? It might come down to me having to prove the teacher that i'm right, that is if you're right.
There are 3 questions:
1.Which type of bone tissue, compact bone or spongy bone, significantly degenerates first in Osteoporosis?
2.As we age, the amount of collagen in the extracellular matrix of bone decreases and bones become more brittle. Identify the osseous tissue cell that secretes collagen.
3.Explain the importance of the integumentary system to bone formation.
Thanks for helping.
Sure, I can help you with these questions. Here are the answers, along with explanations on how to find them:
1. In osteoporosis, both compact and spongy bone can degenerate. However, spongy bone tends to be affected earlier and more severely than compact bone. This is because spongy bone has a higher surface area and is more metabolically active than compact bone, making it more susceptible to the effects of osteoporosis.
To find a source for this information, you can refer to reputable medical websites, textbooks on bone diseases, or research articles on osteoporosis. Some reliable sources include:
- National Osteoporosis Foundation: www.nof.org
- Mayo Clinic: www.mayoclinic.org
- National Institute of Arthritis and Musculoskeletal and Skin Diseases: www.niams.nih.gov
2. The osseous tissue cell that secretes collagen is called an osteoblast. Osteoblasts are responsible for the synthesis and secretion of collagen and other organic components of the bone matrix. They play a critical role in bone formation and repair.
To verify this answer, you can refer to histology or anatomy textbooks that discuss bone physiology and cell types. Additionally, academic websites such as those of universities or educational institutions can provide reliable information.
3. The integumentary system, which includes the skin, plays a crucial role in bone formation through several mechanisms. Here are a few ways in which the integumentary system is important for bone formation:
- Vitamin D synthesis: The skin produces vitamin D when exposed to sunlight. Vitamin D is necessary for calcium absorption, which is critical for bone mineralization and strength.
- Protection: The skin acts as a barrier, shielding the underlying bones from external injuries and infections that could hinder bone formation or healing.
- Temperature regulation: The skin helps maintain body temperature, providing an optimal environment for bone cell activity and development.
- Nerve supply: The integumentary system includes sensory receptors that provide feedback to the central nervous system. This feedback helps regulate bone remodeling and repair processes.
To find additional sources on the importance of the integumentary system to bone formation, you can refer to anatomy and physiology textbooks, articles on bone biology, or research papers on the relationship between the integumentary system and skeletal health.
Remember to always check the relevance and credibility of your sources before using them as references in academic settings.
