A Univ. of Nev. Strep throat in children generally lasts for about a week (two to seven days). The symptoms can be severe, causing levels of discomfort during swallowing that make a child not want to eat. Other symptoms include redness and white patches in the throat, swollen lymph nodes and fever.
2. chondroblasts-immature cartilage cells. Secrete extracellular matrix, but are not yet rigidly embedded in that matrix. 3. chondrocytes-mature cartilage cells that are embedded in rigid extracellular matrix. These cells reside in small spaces within the matrix that are called lacunae.
The perichondrium as its name suggests surrounds cartilage. It is composed of a dense connective tissue. The innermost layer of that surrounding connective tissue has stem cells that can divide and provide a reservoir of cells that can secrete cartilage matrix. This is called the chondrogenic layer.he predominant fiber in the interterritorial matrix of cartilage is composed of elastin (the elastic fiber). Scan the 5x image noting the cartilage, its perichondrium and the elastic cartilage. Again, as in hyaline cartilage, the spaces are the lacunae each of which contains a chondrocyte.
