Session 05/06

Epithelial tissue is

• Avascularized
  

• Vascularized
  

• very rich in blood supply

• made of different types of cells

What type of epithelium is composed of cells which all touch the basement membrane & is only one cell layer thick?

• Stratified squamous epithelium

• Transitional epithelium

• Stratified cuboidal epithelium

• Pseudostratified epithelium

Cartilage

• is a form of skeletal connective tissue
  

• is a vascularized tissue
  

• had nerve supply
  

• is made of hyaline, reticular & elastic cartilage

Concerning the matrix in hyaline cartilage

• collagen fibrils are thin and made of type II collagen
  

• collagen fibrils have the characteristic 86 nm banding
  

• 40 % of its net weight is made from water
  

• sulfated peptidoglycans are concentrated around the lacuna

Regarding epithelial tissues

• Are composed of polarized cells

• Derive only from ectoderm

• is characterized by the presence of distant cells

• the cells are dispersed in an abundant ECM

Concerning the chondrocytes

• have rich mitotic activity

• are located in the chondrogenic layer of the perichondrium

• are enclosed in small lacunae without a wall

• Have a star shape

All types of cartilage

• Are vascularized

• Are innervated

• Have perichondrium

• None of the above

The epithelium that lines the walls and covers the contents of the closed cavities is called

The epithelium that lines the vascular system is called

Hyaline cartilage constitutes the largest part of the fetal skeleton

• True

• False
