The structure indicated is the epiphyseal line.. 1 Answer. The epiphyseal plate is a plate of hyaline cartilage found in children and adolescents, located in the metaphysis at the ends of each long bone. Some of the long bones include: The femur; The tibia; The fibula; Humerus; Radius; Ulna; The role of the epiphyseal plate is to turn new cartilage into bone. All the above mentioned features co-ordinate during the process of bone growth and or lengthening . Which of the following is the single most important stimulus for epiphyseal plate activity during infancy and childhood? As the child grows, the cartilage hardens into bone.

Answer Save. 1 decade ago. 3. a flat vessel, usually a petri dish , containing sterile solid medium for the culture of microorganisms. Expert Answer . The epiphyseal plate is an area at the long end of the bone that contains growing bone. Femoral non-elongating rodding in osteogenesis imperfecta - the importance of purchasing epiphyseal plate. During infancy and childhood the single most important stimulus for bone growth is growth hormone. Briefly outline the steps involved in fracture repair (2 marks). During infancy and childhood, the single most important stimulus of epiphyseal plate activity is __ __ released by the anterior pituitary gland. epiphyseal plate: [ plāt ] 1. a flat stratum or layer . 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. proportions as it grows . Instead, growth occurs at each end of the bone around the growth plate. The epiphyseal plate, a hyaline cartilage disk in the wider portion of a long bone, called metaphysis, is situated between the growth site and diaphysis, the midsection of the bone. The growth plate, also known as epiphyseal plate or physis, is the area of growing tissue near the ends of our long bones. An open epiphyseal plate was defined as the region where cartilage cells were oriented regularly, with the typical zones of an epiphyseal plate, and with more than six cells corresponding to the area of hypertrophy . Completion of growth: Once the growth plate is fused the bone growth is completed. In children and young adults, the epiphyses are separated from the diaphysis by epiphyseal cartilage or plates, where bone grows in length. There is the bony part, the fibrous and cartilaginous part among other features that make up the growth plate. growth hormone. In brief, skeletal growth at the epiphyseal plate is active and constantly changing. ANATOMY . The epiphyseal plate is an important part of the long bones in the body. The long bones of the body do not grow from the center outward. Estrogen and testosterone release at puberty initiates closure of the epiphyseal plates.When bone growth is complete, the epiphyseal cartilage is replaced with bone, which joins it to the diaphysis. Epiphyseal cartilage is a type of cartilage found at each end of a long bone related to bone elongation, or growth. The epiphyseal line the part of the bone that replaces the epiphyseal growth plate in long bones once a person has reached their full adult height. There is no change in height after that. It usually appears during prenatal development in the central part of each developing bone. The epiphyseal plate may also he crushed in severe abduction and adduction injuries of the ankle. It seems that SOX9 is downregulated in the chondrocytes that are in hypertrophy in the growth plate during ossification. There is no change in height after that. During infancy and childhood, the most important stimulus of epiphyseal plate activity is _____. 6. What is the Epiphyseal Plate?

As people develop, the bone grows longer as a result of activity inside this area. The epiphyseal plate is located at the ends of the long skeletal bones. jim72051. Epiphyseal plates ossify and form epiphyseal lines. The epiphyseal growth plate is the main site of longitudinal growth of the long bones. The avian epiphyseal growth plate plays an important role in skeletal development. The epiphyseal plate is the area of growth in a long bone. The epiphyseal plinth (physis, physis calcaneus, growth plate, or epiphysis) is a complex growth and osteological plate on each side of each long bones, in each osteophyte at the ends of the bone. The epiphyseal plate is where the longitudinal growth of long bones takes place. Injury in the epiphyseal plate can cause irreversible damage to the growing cells; therefore, it can cause problems in the elongation and growth of the bone. Which of the following is a bone marking name that … The epiphyseal plate comprises four zones: reserve zone, proliferative zone, zone of maturation and hypertrophy, and zone of calcified matrix. Compared with the mammalian species, the avian growth plate contains more cells, is less well organized and appears more susceptible to malformation. (b) Epiphyseal lines are the remnants of epiphyseal plates in a mature bone. it is at the end of long bones of … How Growth takes place at the Epiphyseal Plate. c.) primary ossification center is the first area of a bone to start ossifying. During childhood, the epiphyseal plate matures and its total width decreases. Made from a matrix of elastic protein fibers in a gelatinous protein base called chondroitin, this tissue lacks blood vessels and regenerative abilities. Lv 4. C) calcium. Epiphyseal Plate. Cartilage is a connective tissue that provides flexible support attaching the bones of the skeleton. 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.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). Answer: D. 13. Relevance. The epiphyseal plate contains cartilage used for producing bone and the epiphyseal line is formed after the epiphyseal plate has stopped producing bone.
