Question

anatomy and physiology dec. final
what part of the bone is letter b?
options: diaphysis, metaphysis, medullary cavity, epiphysis

Explanation:

To determine the part of the bone labeled "B", we analyze the options:

• Diaphysis is the shaft of a long bone.
• Metaphysis is the region between epiphysis and diaphysis (involves growth plate remnants).
• Medullary Cavity is the hollow space inside the diaphysis (contains marrow).
• Epiphysis is the end part of a long bone (usually rounded, involved in articulation).

In a typical long - bone diagram, the epiphysis is the rounded end. So if "B" labels the end part of the long bone (as per standard anatomy of long bones like femur or humerus), the correct answer is Epiphysis.

Answer:

D. Epiphysis (assuming the options are ordered as Diaphysis, Metaphysis, Medullary Cavity, Epiphysis with D being Epiphysis; if the option order is different, adjust the identifier but the text is Epiphysis)
