The growth plate, also known as the epiphyseal plate is a thin layer of cartilage that lies between the epiphyses and metaphyses, and is where the growth of long bones takes place. The growth plate, also known as the epiphyseal plate or physis, is the area of growing tissue near the end of the long bones in children and adolescents. The physis (growth plate or epiphyseal plate) is a hyaline cartilage plate in the metaphy s is at the ends of each of the long bones. epiphyseal plate: [ plāt ] 1. a flat stratum or layer . The epiphyseal plates are also known as the growth plates. (b) Epiphyseal lines are the remnants of epiphyseal plates in a mature bone. Homework Help. 3. a flat vessel, usually a petri dish , containing sterile solid medium for the culture of microorganisms. This depends on the degree of certainty you need and how far you are willing to go to learn this answer. During infancy and childhood, the skeleton grows rapidly and is very vulnerable. The epiphyseal plate allows the diaphysis of the bone to increase in length until early adulthood. 2. dental plate ; sometimes, by extension, incorrectly used to designate a complete denture. When these are thick, especially due to injury, they can eventually cause a deformity in the child's growth and development. All that remains of the epiphyseal plate is the epiphyseal line. When the chondrocytes in the epiphyseal plate cease their proliferation and bone replaces the cartilage, longitudinal growth stops. Personalized courses, with or without credits. Injury to the developing epiphyseal cartilage and secondary ossification center (SOC) can lead to … EDITOR’S NOTE: you should add an xray of a epiphyseal plate vs line Booster Classes. 3.7 million tough questions answered. Get the detailed answer: What is the difference between the epiphyseal plate and the epiphyseal line? Switch to. Figure 6.4.4 – Progression from Epiphyseal Plate to Epiphyseal Line: As a bone matures, the epiphyseal plate progresses to an epiphyseal line. The growth plate determines the future length and shape of … The physis is … Each long bone has at least two growth plates: one at each end. The apophysis of the proximal 5 th metatarsal (plural apophyses) lies laterally and is oriented longitudinally parallel to the shaft.. Apophysis of the fifth metatarsal base appears on plain radiographs at age 12 for boys and 10 for girls. Fusion of the apophysis to the metatarsal base usually occurs within the following 2-4 years 3,4.. 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. Home. 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. (a) Epiphyseal plates are visible in a growing bone. Epiphyseal plates support growth of long bones. Differential diagnosis When growth stops, the epiphyseal plate cartilage is replaced with bone, then becoming the epiphyseal line. The plate is only found in children and adolescents; in adults, who have stopped growing, the plate is replaced by an epiphyseal line.This replacement is known as epiphyseal closure or growth plate fusion.Complete fusion happens on average between ages 12–18 for girls (with the most common being 15-16 years for girls) and 14–19 for boys (with the most common being 18-19 years for boys). Epiphyseal disorders are an important source of morbidity in children. Study Guides. Figure \(\PageIndex{1}\): From epiphyseal plate to epiphyseal line: As a bone matures, the epiphyseal plate progresses to an epiphyseal line. The epiphyseal line is a remnant of the EPIPHYSEAL PLATE, which is a cartilage plate that serves as a growth area for long bone lengthening.
