EPIPHYSEAL PLATE Meaning and
Definition
-
The term "epiphyseal plate" refers to a crucial component of long bones in humans and other vertebrates. Also known as the growth plate, it is a thin, cartilaginous layer located at the ends of long bones where growth occurs.
The epiphyseal plate is primarily responsible for longitudinal bone growth, determining the height and overall bone length of an individual during their growth years. It is found in the metaphysis region, between the epiphysis (the rounded end of the bone) and the diaphysis (the shaft of the bone).
During childhood and adolescence, the epiphyseal plate is active and constantly undergoes a process called ossification. This process involves the transformation of cartilage into bone through the deposition of calcium and phosphorus. As long as the epiphyseal plates are active, bones will continue to grow in length. However, once an individual reaches skeletal maturity, usually around the late teens or early twenties, the epiphyseal plates fuse and cease bone growth.
The epiphyseal plate is composed of multiple zones, each with unique functions. These zones include the reserve zone, proliferative zone, hypertrophic zone, and the ossification zone. Each zone performs a specific role in the process of bone growth and ultimately determines the final length and shape of the bone. Various hormones and growth factors play a crucial role in the regulation of the epiphyseal plate, ensuring the balance between growth and closure at the appropriate time.
In summary, the epiphyseal plate is a vital anatomical structure present in the long bones of the body that determines longitudinal bone growth during childhood and adolescence.

Etymology of EPIPHYSEAL PLATE
The word "epiphyseal" is derived from the Greek word "epiphysis", meaning "a growth upon", which comes from the combination of "epi", meaning "upon", and "physis", meaning "nature" or "growth".
The term "plate" refers to the structure that consists of layers of cartilage found at the ends of long bones in children and adolescents. It allows for longitudinal bone growth until it ossifies and is replaced by bone, which results in the closure of the growth plate.
