What type of bone cells are immature bone cells that secrete the components of the osteoid? A. Osteogenic cells B. Osteocytes C. Osteoblasts D. Osteoclasts

Break Down the Problem

1. Identify the types of bone cells mentioned in the options.
2. Determine which cell type is responsible for secreting the components of osteoid.

Relevant Concepts

• Osteogenic Cells: These are the stem cells derived from mesenchyme; they can differentiate into osteoblasts.
• Osteocytes: Mature bone cells that maintain bone tissue and communicate with other cells; they do not secrete osteoid.
• Osteoblasts: Cells responsible for bone formation; they secrete osteoid, which includes collagen and other proteins.
• Osteoclasts: Cells that resorb (break down) bone tissue; they do not secrete osteoid.

Analysis and Detail

• Among the options provided:
  1. Option A (Osteogenic cells) are precursors but do not secrete osteoid directly.
  2. Option B (Osteocytes) maintain bone rather than secrete the osteoid.
  3. Option C (Osteoblasts) are the cells that specifically secrete osteoid components.
  4. Option D (Osteoclasts) are involved in bone resorption and also do not secrete osteoid.

Verify and Summarize

The cells that actively secrete the components of osteoid are definitely osteoblasts, making them the correct answer when considering all options.

Final Answer

C. Osteoblasts are the immature bone cells that secrete the components of the osteoid.
