The epiphyseal plate, epiphysial plate, physis, or growth plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length).
In children, bone age serves as a measure of physiological maturity and aids in the diagnosis of growth abnormalities, endocrine disorders, and other medical conditions. [ 1 ] [ 2 ] [ 3 ] As a person grows from fetal life through childhood, puberty , and finishes growth as a young adult, the bones of the skeleton change in size and shape.
It contains the growth plate, the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses. The metaphysis contains a diverse population of cells including mesenchymal stem cells , which give rise to bone and fat cells, as well as hematopoietic stem cells which give rise to a variety of ...
Epiphyseal growth plate: This transverse layer lies between the epiphysis and diaphysis. It’s composed of highly active chondrocytes and responsible for longitudinal bone growth. Consequently, the bone elongates at this growth plate until closure occurs at skeletal maturity.
A child bone fracture or a pediatric fracture is a medical condition in which a bone of a child (a person younger than the age of 18) is cracked or broken. [1] About 15% of all injuries in children are fracture injuries. [2] Bone fractures in children are different from adult bone fractures because a child's bones are still growing. Also, more ...
Linear growth takes place in the epiphyseal growth plates (EGP) of long bones. [23] In the growth plate, chondrocytes proliferate, hypertrophy and secrete cartilage extracellular matrix. New cartilage is subsequently remodeled into bone tissue, causing bones to grow longer. [24]

Also known as the growth plate. In a long bone it is a thin disc of hyaline cartilage that is positioned transversely between the epiphysis and metaphysis. In the long bones of humans, the epiphyseal plate disappears by twenty years of age. physis, "the growth part" metaphysis: The region of a long bone lying between the epiphysis and diaphysis.
