BIO 4430 Lecture Notes - Lecture 4: Endochondral Ossification, Hyaline Cartilage, Elastic Cartilage
Document Summary
As the cells of an isogenous group manufacture matrix, they are pushed away from each other, forming separate lacunae and thus enlarging the cartilage from within. This type of growth is called ____ _____ Bone is made of ____ and ____ interstitial growth. collagen i and hydroxyapatite. Cartilage is composed of ______ (in general) and _______ collagen ii and proteoglycans cell that maintains bone maintenance. Chondroblasts that are surrounded by this matrix are referred to as ______ chondrocytes. Chondrocytes are still capable of cell division, forming a cluster of two to four or more cells in a lacuna. These groups are known as ______ groups isogenous. Chondrocytes mature, hypertrophy, and accumulate glycogen in their cytoplasm. The matrix between their lacunae narrows with a corresponding growth of lacunae. Chondrocytes, rapidly proliferating, form rows of isogenous cells that parallel the direction of bone growth.
