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).
An epiphysis (from Ancient Greek ἐπί (epí) 'on top of' and φύσις (phúsis) 'growth'; pl.: epiphyses) is one of the rounded ends or tips of a long bone that ossify from a secondary center of ossification. [3][4] Between the epiphysis and diaphysis (the long midsection of the long bone) lies the metaphysis, including the epiphyseal ...
Epiphyseal line. An epiphyseal line is an epiphyseal plate that has become ossified. [1] The process of it forming from an epiphyseal plate is named epiphyseal closure. [2] In adult humans, it marks the point of fusion between the epiphysis and the metaphysis. [3][4]
Endochondral ossification[1][2] is one of the two essential pathways by which bone tissue is produced during fetal development of the mammalian skeletal system, the other pathway being intramembranous ossification. Both endochondral and intramembranous processes initiate from a precursor mesenchymal tissue, but their transformations into bone ...
A Salter–Harris fracture is a fracture that involves the epiphyseal plate (growth plate) of a bone, specifically the zone of provisional calcification. [2] It is thus a form of child bone fracture. It is a common injury found in children, occurring in 15% of childhood long bone fractures. [3] This type of fracture and its classification ...
Obesity, hypothyroidism. Slipped capital femoral epiphysis (SCFE or skiffy, slipped upper femoral epiphysis, SUFE or souffy, coxa vara adolescentium) is a medical term referring to a fracture through the growth plate (physis), which results in slippage of the overlying end of the femur (metaphysis). Normally, the head of the femur, called the ...
Triradiate cartilage. The acetabulum. TA2. 1859. Anatomical terminology. [edit on Wikidata] The triradiate cartilage (in Latin cartilago ypsiloformis) is the Y-shaped epiphyseal plate between the ilium, ischium and pubis to form the acetabulum of the os coxae.
Fibrous layer of the periosteum. o. Layer of osteoblasts. im. Subperiosteal bony deposit. There are two types of ossification centers – primary and secondary. A primary ossification center is the first area of a bone to start ossifying. It usually appears during prenatal development in the central part of each developing bone.
