Localization of fibrous cartilage is:

• external auditory canal

• intervertebral disc

•  connection of the ribs to the sternum

• auricle

Having no perichondrium, hyaline cartilage is localized on ...

• articular surface

• larynxes

• connecting the ribs to the sternum

• large-caliber bronchi

Localization of elastic cartilage is:

• intervertebral discs

• connection of ribs with sternum

• horns and sphenoid cartilages of the larynx

• articular cartilage

The source of cartilage tissue development is ...

• yolk sacectoderm

• ectoderm

• endoderm

• mesenchyme

The intervertebral disc is a connection of the type:

• synostosis

• syndesmosis's

• synchondrosis

• arthrosis

Interstitial cartilage growth is called:

• chondrocyte division in isogenic groups

• synthesis of glycosaminoglycans and proteoglycans

• perichondrium chondroblast proliferation

• cartilage growth due to interstitial tissue

Electron microscopic examination of hyaline cartilage reveals cells with a well-developed granular endoplasmic reticulum, Golgi complex. These cells perform a function ...

• destruction of the intercellular substance

• formation of intercellular substance

• glycogen deposition

• fat deposit

On a histological preparation of cartilage, isogenic groups of cells are detected. Initial in the formation of these groups are:

• chondrocytes type I

• chondroblasts

• prechondroblasts

• chondrocytes type II

Diagnose the tissue in which the cells are placed singly and in iso groups, and fibrous structures are not visible in the intercellular substance.

• smooth muscleepithelial tissue

• epithelial tissue

• hyaline cartilage

• fibrous cartilage

On micropreparations of a biopsy specimen from the larynx, tissue is observed in which the cells are placed individually and also form isogenic groups of cells that lie in the same cavity. Collagen and elastic fibers are histologically revealed. The tumor developed from ....

• fibrous cartilage

• elastic cartilage

• smooth muscle tissue
