What are Tanner stages?

What are Tanner stages?

• A. Stages that describe progression from pre-puberty to full physical maturity, used to measure development.
• B. Phases of sleep cycles.
• C. Stages of cognitive development in adolescence.
• D. Steps in the adrenal axis maturation.

Answer: (C)

Tanner stages describe puberty-related physical maturation as a five-stage sequence from prepubertal to fully mature. They’re based on observable sexual characteristics rather than cognition or sleep. In girls, stages hinge on breast development and pubic hair, while in boys they focus on testicular size and genital development along with pubic hair growth. The system helps clinicians track how puberty is advancing and estimate the timing of maturation, which can inform decisions about growth and development concerns. They are not about sleep cycles, cognitive development, or adrenal axis processes, which is why the other options don’t fit.
