Extra cellular matrix

What is the ecm?

• structural support outside of the cell that essentially packages or places/organizes cells into organs and tissues giving the mechanical properties to tissues/organs.

•  is the predominant glycoprotein

• is the main glycoprotein of the basement membranes

• stands for glycoprotein, which plays a major role in the process of cell migration and their subsequent adhesion to the substrate, exists in two forms - tissue and plasma. 

What are the function of the ecm?

• Coiled into a spiral

• mechanical properties to tissues

• provides strength, resilience, cusionining, and adhesion

• provides elastin,gel-like

What is the ECM protein that is a long cable that provides strength and is very abundant (about 25% of proteins in the body)

• Fibronectin

• Lamina

• Proteoglycan

• Collagen

What is proteoglycan composed of

• Fibronectin and others

• proteins and glycosaminoglycans (complex carbohydrates

• Lamina and collagen

• Proteins and collagen (ecm)

What is the function of proteoglycans

• to provide a gel-like material that provides cushioning to the extracellulat matrix

• forming a lattice structure of the extracellular matrix

• involved in the implementation of protective reactions of the body

• the predominant glycoprotein of the extracellular matrix.

fibronectin

• the predominant glycoprotein of the extracellular matrix.

• a glycoprotein that helps animal cells attach to the extracellular matrix.

• the main glycoprotein of the basement membranes, the thin extracellular matrix surrounding epithelial tissues, nerves, fat cells,

• the main protein of the connective tissue of the human body

…is found in the intercellular material that binds all internal organs into a single whole - into the body

• Lamina or laminin

• Collagen

• Fibronectin

• Proteoglycan

Hair, muscles, and vital organs are also formed by…

• Proteoglycan

• Lamina

• Fibronectin

• Collagen

… promotes adhesion between the cell and the main substance of connective tissue.

• Lamina

• Collagen

• Fibronectin

• The cell

Collagen fibers are elastic.
