Question

multiple choice question

which stem cells remain located between a muscle fiber and the endomysium?

satellite cells
fibrocytes
myocytes
myoblasts

Explanation:

Identify the anatomical location of muscle stem cells

Using the Satellite Cells and Endomysium knowledge points

• Satellite cells are specialized myogenic stem cells located between the sarcolemma of a skeletal muscle fiber and its surrounding basement membrane (which is closely associated with the endomysium).
• These cells remain quiescent under normal conditions but proliferate and differentiate to repair or regenerate damaged muscle tissue.

Evaluate the incorrect options

• Fibrocytes are inactive mesenchymal cells in general connective tissue, not muscle-specific stem cells.
• Myocytes are fully differentiated mature muscle cells, not stem cells.
• Myoblasts are embryonic progenitor cells that fuse to form muscle fibers during development, rather than persisting as quiescent stem cells in mature muscle.

Answer:

• Satellite cells (Correct answer)
• Fibrocytes
• Myocytes
• Myoblasts
