The primary blast cell for bone is the ________.

osteoblast
B
erythroblast
C
chondroblast
D
fibroblast
Verified step by step guidance1
Step 1: Understand the term 'blast cell.' A blast cell is an immature precursor cell that is actively dividing and responsible for producing specific types of tissue.
Step 2: Recall the anatomy of bone tissue. Bone tissue is primarily formed by osteoblasts, which are specialized cells responsible for synthesizing and secreting the bone matrix (collagen and minerals).
Step 3: Differentiate between the options provided:
- Osteoblast: Responsible for bone formation.
- Erythroblast: Precursor to red blood cells, not related to bone.
- Chondroblast: Responsible for cartilage formation, not bone.
- Fibroblast: Produces connective tissue fibers, not bone.
Step 4: Match the correct blast cell to the tissue type. Since the question asks for the primary blast cell for bone, the correct answer is osteoblast.
Step 5: Reinforce the concept by noting that osteoblasts mature into osteocytes, which maintain the bone matrix, highlighting the lifecycle of bone cells.
