The Cells of Connective Tissue
FibroblastsMacrophages
Fat cells/ Adipose cellsMast cells
Plasma cells
Connective Tissue
Fibroblast
Most common in connective tissue Synthesize the extracellular matrix and
collagen. Play a critical role in would healing.
Fibroblast
Macrophage
Phage= to eat Cyte= cell Macrophages are active phagocytes and
type of white blood cell Engulf and destroy foreign material and
damaged cells.
Macrophage
Fat Cells/ Adipose Cells
Synthesizes and contains large globules of fat
Also serve as a fuel reserve
Mast Cells
Mediate inflammatory responses such as hypersensitivity and allergic reactions
Store a number of chemical mediators
Plasma Cells
Involved in the synthesis, storage, and release of antibodies
Each cell can secrete several thousand molecules of antibodies
The Fibers Collagen Fibers- scars are
made of collagen
Elastic Fibers- help restore normal shape after distortion
Reticular Fibers-very delicate
Loose (Areolar) Connective Tissue
Location: Beneath most epithelial layersMuscles
Functions:Nourish nearby epithelial cellsFill spaces between musclesBinds skin to underlying organs.
Adipose Connective Tissue
Locations: JointsSome organs ( Kidney, heart)Lower layer of skinBehind eye balls
Functions:CushioningInsulationEnergy storage
Hayline Cartilage
Locations: Ends of bones in many jointsSupporting rings of trachea
Functions:Development and growth of most bonesKeep respiratory passageway open
Elastic Cartilage:
Locations: Ears (External)Larynx
Functions:Framework for ear and voicebox.
Fibrocartilage:
Locations:VertebraeBones in the kneePelvic girdle
Functions:Shock absorber, cushions
