Chondrocytes divide rapidly and form columns of stacked cells at the epiphyseal cartilage of short and long bones. During the growth towards the ends of bones, the chondrocytes that were originally dividing in closest proximity to the center of the bone (still within the epiphyseal cartilage), die and become resorbed matrix. This matrix soon becomes calcified. Because the proliferation and destruction of chondrocytes occur at the same rate, the epiphyseal plate does not change thickness. It does, however, grow away from the middle of the bone.

What are the fuctions of the epiphyseal plate?
Epiphyseal plates are the places in the bones where growth occurs. Bone cells and tissues form and grow here.
What kind of bones are epiphyseal plates responsible for?
Long bones have these plates at each end. They are found with bones that grow longer over time.
Will a person get taller if they have a epiphyseal plate?
Yes, a person can grow taller if they have an epiphyseal plate, also known as the growth plate. This cartilage plate is located at the ends of long bones and is responsible for bone lengthening during childhood and adolescence. Once the epiphyseal plates close, typically after puberty, further height increase is no longer possible. Thus, as long as the epiphyseal plates are open and active, height growth can occur.
What age does the epiphyseal close?
The epiphyseal plates, or growth plates, typically close between the ages of 18 and 25, depending on the individual and the specific bone in question. In general, females tend to close their growth plates earlier than males, often around ages 16 to 18, while males may continue to grow until about ages 18 to 25. Once these plates close, further growth in length is no longer possible, signaling the end of skeletal growth.
What does epiphyseal closure mean?
Epiphyseal closure refers to the process in which the growth plates, or epiphyseal plates, in long bones fuse, marking the end of longitudinal bone growth. This usually occurs after puberty when hormonal changes lead to the ossification of these cartilage areas. Once closure happens, bones can no longer grow in length, signifying that an individual has reached their final adult height. The timing of epiphyseal closure varies by individual and is influenced by factors such as genetics and sex.
Do you stop to grow because of weightlifting if you started with 15?
No, growth of bones stops when the epiphyseal growth plates in bones undergo changes secondary to increased testosterone levels. The plates are cartilage surfaces at the ends of the bones.
Compare and contrast events occurring on the epiphyseal and diaphyseal faces?
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
What are the epiphyseal plates and why are they useful for determining age?
The epiphyseal plate is an area at the long end of the bone that contains growing bone. As people develop, the bone grows longer as a result of activity inside this area. These plates permit growth after birth, allowing the long bones of the body to extend and a person to grow as he or she reaches maturity. Once growth is completed and the person reaches full maturity and stature, the new bone slowly hardens and the plate turns into the epiphyseal line.The plates fuse over at a stable and predictable rate, so someone with experience can examine a bone and make an estimate of its age. After about age 25, when the epiphyseal lines are fully formed, it is much harder to figure the age.
What happens in the epiphyseal face?
The cartilage cells at the epiphyseal side are continuing to grow and divide mitotiacally and the diaphyseal side are aging and dying and the osteoblast move in to form bone. So they are growing on the ends side and in the middle side of the Epiphyseal line they are dying and form bone.
What structure allows bones to grow in thickness?
Bones grow in length by endochondral ossification. It begins with cartilage that acts like a model of the bone that will grow. The bone grows in length and diameter(appositional). the structure that allows this is the epiphyseal cartilage that seperates the epiphysis from the diaphysis. When the bone is fully grown this cartilage will become bone and simply the epiphyseal line.
This is a layer of hyaline cartilage that allows the diaphysis to grow in length?
The layer you are referring to is the epiphyseal plate, also known as the growth plate. It is found at the ends of long bones in children and adolescents, allowing the bone to lengthen as the cartilage cells multiply and are replaced by new bone tissue. Once growth is complete, the epiphyseal plate ossifies and becomes the epiphyseal line.
How do bones grow in length and width?
Bones grow in length through a process called endochondral ossification, where cartilage is gradually replaced by bone tissue at the growth plates (epiphyseal plates) located at both ends of long bones. In width, bones grow through appositional growth, where osteoblasts on the outer surface of the bone deposit new bone tissue, while osteoclasts on the inner surface resorb bone, allowing the bone to increase in diameter. This dual process ensures that bones can support increased loads and maintain structural integrity as the body grows.
