The Epiphyseal or Growth Plate!
The chondrocytes of the epiphyseal cartilage enlarge and divide, which increases the thickness of the cartilage. On the shaft side, the chondrocytes become ossified, and "chase" the expanding epiphyseal cartilage away from the shaft.
The epiphyseal plate is a section of hyaline cartilage that seperates the epiphysis from the diaphysis in long bones. The growth and ossification of the epiphyseal plate is responsible for the bone growing longer. Articulate cartilage is similar, however, it is found on the outside layer of the epiphysis. It grows and resorbs allowing for the remodelling of the bone. The epiphyseal line is the remains of the epiphyseal plate once it has stopped growing.

The cartilage cells at the epiphyseal side are continuing to grow and divide mitotically, while the ones on the diaphyseal side are aging, dying and then osteoblasts move in to form bone. See this site for more detail and nice diagrams: http://training.seer.cancer.gov/module_a… -JSO

In bone formation, a deficiency of growth hormone will cause DECREASED PROLIFERATION OF THE EPIPHYSEAL PLATE CARTILAGE.

Cartilage plate that servs as a growth area along the bone lenghing, it allows the dialysis of the bone to increase in length until early adulthood. When growth stops the epiphyseal plate is replaced with bone, then becoming the epiphseal line.

the epiphyseal plate is also called the growth plate. it is the area of cartilage between the diaphysis (the long shaft of the bone) and the epiphysis (the end of a bone). the cartilage will expand and go through a process called ossification and turn into bone. when a person is done growing the epiphyseal plate will turn into an epiphyseal line.
estrogen directly causes the epiphyseal plates to close, testosterone is converted to estradiol (estrogen) by aromatase, therefore testosterone causes the epiphyseal plates to close indirectly
