Basal Lamina
The basement membrane is composed of a combination of proteins like collagen, laminin, and fibronectin, as well as glycoproteins and proteoglycans. It forms a gel-like matrix that provides structural support and acts as a barrier between epithelial and connective tissues.
Basement membranes are composed of a thin layer of specialized extracellular matrix proteins like collagen IV, laminin, and proteoglycans. This extracellular matrix has a gel-like consistency and forms a flexible, supportive barrier between epithelial and connective tissues.
Cartilage tissue contains a specialized matrix composed of collagen fibers, proteoglycans, and water. It lacks blood vessels and nerves, and primarily receives nutrients and removes waste through diffusion. Cartilage cells called chondrocytes are responsible for maintaining the extracellular matrix.
Most of the volume in loose connective tissue is made up of ground substance, which is a gel-like material composed of water, glycosaminoglycans, proteoglycans, and glycoproteins. This ground substance provides support and a medium for the movement of nutrients and waste products in the tissue.
Adipose tissue exhibits a loose connective tissue matrix, mainly composed of a network of collagen fibers, proteoglycans, and glycoproteins. This matrix provides structural support and elasticity to the adipose tissue while allowing for the storage of fat cells (adipocytes) within its spaces.
The matrix in cartilage is composed of water, collagen fibers, and proteoglycans. The collagen fibers provide strength and structure, while the proteoglycans help retain water and provide cushioning properties.
Collagen Fibers
Proteoglycans are organic molecules. They are composed of proteins and long chains of complex carbohydrates called glycosaminoglycans.

Coastal cartilage is primarily composed of hyaline cartilage, which consists of a matrix rich in collagen fibers and proteoglycans. This composition provides flexibility and strength, allowing the cartilage to withstand the mechanical stress of rib movement during respiration. Additionally, coastal cartilage contains a high water content, contributing to its resilience and ability to absorb shock.
Bone contains a matrix that includes collagen fibers and mineral components such as hydroxyapatite, which provide strength and rigidity. In contrast, cartilage has a matrix primarily composed of collagen and proteoglycans but lacks the mineralization seen in bone. Additionally, bone contains osteocytes, osteoblasts, and osteoclasts, which are types of cells involved in bone maintenance and remodeling, while cartilage does not have these specialized cells.
Yes, cartilage is made up of cells called chondrocytes that produce and maintain an extracellular matrix composed of collagen and proteoglycans. These molecules are made of atoms such as carbon, hydrogen, oxygen, and nitrogen. So yes, cartilage contains atoms.
