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
