Question

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.
