2-10. CARTILAGE CONNECTIVE TISSUE
a. Cartilage Cells. Cartilage cells are also called chondroblasts.
Cartilage cells are clustered in microscopic pockets within the cartilage matrix. The
cartilage cells produce the material of the matrix.
b. Matrix. The matrix produced by the cartilage cells appears
homogeneous (the same throughout). The matrix also appears amorphous (shapeless).
c. Types of Cartilage CT.
(1) Hyaline cartilage CT. Hyaline cartilage CT appears homogeneous and
clear.
HYALINE = clear
This type of cartilage helps to cover bone surfaces at joints. Hyaline
cartilage is found as incomplete rings which keep the trachea (windpipe) open.
(2) Fibrous cartilage CT. Fibrous cartilage CT includes dense masses of
fibers (of FCT). It is more rigid than hyaline cartilage. The auricle of the external ear
is stiffened with fibrous cartilage.
(3) Calcified cartilage CT. Calcified cartilage CT is cartilage that has
been stiffened by the addition of calcium salts. This is not the same as bone tissue. An
example is the cartilages of the larynx (the voice box) which become calcified with age.
