Connective Tissue and Types of Cartilage Quiz

1. Connective tissue proper with soft matrix, 2) Cartilage with rubbery matrix, 3) Bone with stony hard matrix.

Cartilage is a modified type of connective tissue formed of cells, fibers, and a firm, rubbery matrix.

The three types of cartilage based on matrix components are: 1) Hyaline cartilage, 2) Elastic fibro-cartilage, 3) White fibro-cartilage.

<p>Hyaline cartilage is found in the long bones of the fetal skeleton, respiratory cartilages, articular cartilages, and costal cartilages.</p> Signup and view all the answers

<p>The perichondrium is a vascular connective tissue membrane formed of an outer fibrous layer containing collagen fibers, blood vessels, and fibroblasts, and an inner chondrogenic layer containing chondroblasts.</p> Signup and view all the answers

<p>The functions of the perichondrium are: 1) Nutrition, 2) Attachment to tendons, 3) Cartilage formation during growth and repair.</p> Signup and view all the answers

<p>Chondroblasts are young, active, flat cells with central nuclei, preferably found singly under the perichondrium. Chondrocytes are mature, old cells found deeply in cartilage, either singly or in groups inside lacunae called cell nests.</p> Signup and view all the answers

<p>Chondrocytes have basophilic cytoplasm rich in rough endoplasmic reticulum, ribosomes, Golgi apparatus, glycogen, and alkaline phosphatase enzyme.</p> Signup and view all the answers

<p>Chondrocytes can divide to form groups of two or four cells called cell nests, which are responsible for the growth of cartilage.</p> Signup and view all the answers

<p>The two main functions of chondrocytes are: 1) Formation of cartilage matrix, 2) Cell division for cartilage growth.</p> Signup and view all the answers
