The epiphyseal line is the marking that indicates where the two parts of the bone meet and where the epiphyseal plate was once located in children and young adults. The line may be slightly raised and rougher than the surrounding bone. Synonym (s): linea epiphysialis [TA]. 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). There are three types of cartilage: hyaline, elastic, and fibrocartilage. An epiphyseal line is visible on a standard x-ray. The line of junction of the epiphysis and diaphysis of a long bone where growth in length occurs. The Epiphyseal plate contains cartilage used for producing bone. … Die Epiphysenfuge ist die zwischen der Epiphyse und der Diaphyse der Röhrenknochen gelegene Wachstumszone des Knochens. Experts are waiting 24/7 to provide step-by-step solutions in as fast as 30 minutes!*. The plate's chondrocytes are under constant division by mitosis. al line (ep'i-fiz'ē-ăl līn) [TA] The line of junction of the epiphysis and diaphysis of a long bone where growth in length occurs. The epiphyseal line is the remains of the epiphyseal plate once it has stopped growing. The epiphyseal plate (or epiphysial plate, physis, or growth plate) is a hyaline cartilage plate in the metaphysis at each end of a long bone. The structure indicated is the epiphyseal line. OTHER SETS BY THIS CREATOR. A disc of hyaline cartilage that grows during childhood to lenghten the bone. The cartilage inside the epiphyseal plate is substituted through bone around the ages of 18-21 when a bone ceases to grow lengthwise. A person with abnormal bone growth may have a visible crack or an uneven line showing on an x-ray. braden_spicer.

Q: Describe how various aspects of the body’s design serve to protect vital organs and limit infection. Epiphyseal Plate. Expert Answer . The plate is only found in children and adolescents; in adults, who have stopped growing, the plate is replaced by an epiphyseal line. Epiphyseal Line. These cells hypertrophy, changing the shape of the flattened cells to an almost cuboidal configuration. *Response times vary by subject and question complexity. [7], The growth plate has a very specific morphology in having a zonal arrangement as follows:[8]. Maths a. any straight one-dimensional geometrical element whose identity is determined by two points. A diagram of the anatomy of a bone, showing the epiphyseal cartilage. Where is the epiphyseal plate located in bone? Estrogen and progesterone are the two important sex hormones in the female body. The epiphyseal plate is a hyaline cartilage plate in the metaphysis at each end of a long bone. Urine formation occurs in three processes: A) The epiphyseal line is calcified B) Fibroblasts replace trabeculae C) Lamellar bone is converted into woven bone D) Metaphyseal chondrocytes are calcified E) Osteoclasts replace cartilage. Terms in this set (2) Epiphyseal Line. As the older chondrocytes degenerate, osteoblasts ossify the remains to form new bone. The growth plates (epiphyseal plate) is present on both sides of the bone and is converted into a epiphyseal line when the growth stops. The epiphyseal line is a line at the end of long bones that are found in adults. Group of answer choices Other articles where Epiphyseal plate is discussed: cartilage: …plate of cartilage, called the epiphyseal plate, persists at the ends of growing bones, finally becoming ossified itself only when the bone behind it has completed its growth. The resulting daughter cells line up into columns of flattened cells, much like a stack of pancakes.
