The global average height for women is 5'4" and men is 5'9". 14.5% of American men are at least 6 feet tall, 1% of American women reach 6 feet. Which factors help to explain this?
A. Girls start puberty at a younger age so have fewer years with GH and IGF
B. Estrogen causes slow growth while testosterone causes rapid growth
C. Estrogen stimulates the epiphyseal plate to close rapidly while testosterone stimulates it to close slowly
D. Testosterone stimulates osteoblasts to work faster
Answer (2)
The difference in height averages between American men and women largely stems from hormonal influences. Estrogen leads to faster epiphyseal plate closure in women, while testosterone allows men a longer growth period. Additionally, testosterone enhances osteoblast activity, contributing to greater height in men. ;
The difference in height averages between American men and women is primarily due to hormonal influences. Estrogen leads to faster closure of the growth plates in women, while testosterone allows for a longer growth period in men. Additionally, testosterone stimulates bone growth, contributing to this height difference.
