Connective Tissue Proper: Cells, Fibers, & Types

Front

What is the primary function of melanocytes?

Back

Melanocytes are cells that produce melanin, the pigment responsible for skin color and protection against UV radiation.

Front

What are fibroblasts?

Back

Fibroblasts are the most common cells in connective tissue proper, responsible for producing collagen and other fibers.

Front

What role do macrophages play in connective tissue?

Back

Macrophages are immune cells that engulf and digest cellular debris, pathogens, and foreign substances.

Front

What are eosinophils and their function?

Back

Eosinophils are a type of white blood cell involved in allergic reactions and combating parasitic infections.

Front

What are reticular fibers?

Back

Reticular fibers are thin, branched fibers that form a supportive network in various tissues, particularly in lymphoid organs.

Front

What is the difference between collagen fibers and elastic fibers?

Back

Collagen fibers provide strength and resistance to stretching, while elastic fibers allow tissues to stretch and return to their original shape.

Front

Define adipocytes and their function.

Back

Adipocytes, or fat cells, store energy in the form of fat and provide insulation and cushioning for organs.

Front

What is the ground substance in connective tissue?

Back

Ground substance is the non-cellular material in connective tissue that fills the space between cells and fibers, providing support and medium for nutrient exchange.

Front

What are the main types of connective tissue proper?

Back

The main types of connective tissue proper are loose connective tissue (areolar, adipose, reticular) and dense connective tissue (dense regular, dense irregular, elastic).

Front

How do mast cells contribute to the immune response?

Back

Mast cells release histamine and other chemicals during allergic reactions, contributing to inflammation and the immune response.
