Question

which of the following is a characteristic of bone?
compact bone is organized into trabeculae.
canaliculi pass through the matrix to allow for cartilage adherence.
the matrix is mostly collagen.
the matrix contains osteoclasts and chondroblasts.
the matrix is very dense and contains deposits of calcium salts.

Explanation:

1. Compact bone is organized into osteons, not trabeculae (trabeculae are in spongy bone).
2. Canaliculi in bone are for communication between osteocytes, not for cartilage adherence.
3. While collagen is present in bone matrix, it's not the main component.
4. Osteoclasts and chondroblasts are cells, not components of the matrix.
5. The bone matrix is dense and has calcium - salt deposits (hydroxyapatite), which gives bone its hardness.

Answer:

The matrix is very dense and contains deposits of calcium salts.
