What is the primary feature of Stage 5 in the Tanner scale for females?

• A. Pubic hair is straight and sparse
• B. No palpable breast tissue
• C. Papilla projects beyond the contour of the areola
• D. Breast buds begin to develop

Answer: (C)

Stage 5 in the Tanner scale for females indicates full maturation of the breasts, where the papilla (nipple) projects beyond the contour of the areola. This is a clear sign of completed breast development, which occurs after the earlier stages characterized by the growth of breast buds and the development of the areola. In this final stage, individuals have typically reached their peak levels of estrogen and other hormones, leading to well-defined breast structures.

In contrast, earlier stages on the Tanner scale involve varying degrees of breast development and hair growth, such as sparse pubic hair or the initial formation of breast buds, which have not reached the maturity seen in Stage 5. Therefore, the indication of the nipple's projection signifies the transition into complete secondary sexual characteristics that are assessed in this stage of development.
