What are fibroblasts?

Back

Fibroblasts are cells in the tissue matrix that produce collagen and other fibers, playing a crucial role in the structural framework of tissues.

Front

What is the function of reticular fibers?

Back

Reticular fibers provide a supportive framework for soft organs, helping to maintain their shape and structure.

Front

What is the endothelium?

Back

The endothelium is a thin layer of cells that lines blood vessels and the heart, playing a key role in vascular health and function.

Front

What type of cartilage is difficult to view with normal stains?

Back

Hyaline cartilage is the type of cartilage that is often difficult to view with normal stains due to its glassy appearance.

Front

What are adipocytes?

Back

Adipocytes are fat cells found in the tissue matrix that store energy in the form of fat.

Front

Define collagen fibers.

Back

Collagen fibers are strong, flexible protein fibers that provide structural support to tissues and organs.

Front

What is the role of elastic fibers?

Back

Elastic fibers allow tissues to stretch and return to their original shape, providing elasticity to structures like skin and blood vessels.

Front

What is the function of macrophages in the tissue matrix?

Back

Macrophages are immune cells that engulf and digest cellular debris and pathogens, playing a vital role in tissue maintenance and defense.

Front

What is ground substance in the tissue matrix?

Back

Ground substance is the non-cellular material in the tissue matrix that fills the space between cells and fibers, providing support and facilitating the exchange of nutrients.

Front

What is the difference between hyaline cartilage and fibrocartilage?

Back

Hyaline cartilage is smooth and glassy, providing support with some flexibility, while fibrocartilage is tougher and provides more resistance to compression.
