Chondrocyte Mitosis In The Articular Cartilage Of Femoral

à 16 avril

Cartilage is a group of tissues produced by chondrocytes that is characterized by a relative lack of vascularity and consists of cells surrounded by a specialized extracellular matrix composed predominantly of type II collagen and proteoglycan, often in the form of proteoglycan aggregate. This chapter explains that cartilage, much like otherWhen chondrocytes in lacunae divide and form new matrix, it leads to an expansion of the cartilage tissue from within. Cartilage has a flexible matrix that can accommodate mitosis of chondrocytes. back 31. True. front 32. Cartilage has a flexible matrix that can accommodate mitosis of chondrocytes. back 50. True. front 51.- Unspecialized cells from mesenchyme develop into chondrocytes, which divide and form cartilage. - Chondrocytes in the lacunae divide and secrete matrix, allowing the cartilage to grow from within.

Closure of the epiphyseal plate stops all bone growth. False. T/F The dividing cartilage cells in the epiphyseal plate are located farthest from the shaft. True. An osteon contains osteocytes, lamellae, and a central canal, and is found in compact bone only. True• Growth of Cartilage o Unlike bone, which has a hard matrix, cartilage has a flexible matrix which can accommodate mitosis; ideal environment to lay down embryonic skeleton and provide new skeletal growth. o Typically, cartilage growth ends during adolescence when skeleton stops growing. o Cartilage grows in two ways

Cartilage has a flexible matrix that can accommodate mitosis of chondrocytes. TRUE. 39. The cartilage matrix begins to deteriorate. D) A medullary cavity forms. cartilage. D) Chondrocytes in the lacunae divide and secrete matrix, allowing the cartilage to grow fromDuring fetal development, a framework is laid down that determines where bones will form. This framework is a flexible, semi-solid matrix produced by chondroblasts and consists of hyaluronic acid, chondroitin sulfate, collagen fibers, and water. As the matrix surrounds and isolates chondroblasts, they are called chondrocytes.T/F Cartilage has a flexible matrix that can accommodate mitosis of chondrocytes. True .

Autoradiographic studies using thymidine-3H reveal the mitosis of chondrocytes in degenerated joints, i.e. joints having secondary osteoarthritis or aseptic necrosis of the femoral head. The findings obtained provide additional support for the recent investigations regarding chondrocyte mitosis in primary osteoarthritic cartilage. Histologic and histochemical examinations suggest that a loss of glycosaminoglycans in the matrix is evidence for conversion of chondrocyte activity to mitosis which occurs, however, within the limit of "the point of irreversibility", analogous to the observations from the biochemical point of view. Biomechanical and nutritional factors are also discussed in relation to the results obtained from cartilages of the femoral heads in cases of femoral neck fracture and aseptic necrosis of the femoral head.
