epiphyseal line

The point of union of the primary and secondary ossification centers is called the epiphyseal line.

Individuals of both sexes will be tall, as lack of estrogen does not bring the epiphyseal lines to closure.

The plate is found in children and adolescents; in adults, who have stopped growing, the plate is replaced by an epiphyseal line.

"That's a remnant epiphyseal line."

A reported male with EIS was tall as estrogens were unable to act to close the epiphyseal line, at risk for osteoporosis, and sterile (suggesting that in humans estrogens are necessary for reproduction).

In adults, this is small and doesn't have much importance but in children who's epiphyseal line is still made of cartilage which doesn't allow blood supply through it, it helps to supply the head and neck of femur on its own.
