The Cells of Connective Tissue

1
The Cells of Connective Tissue

• Fibroblasts
• Macrophages
• Fat cells/ Adipose cells
• Mast cells
• Plasma cells

2
Connective Tissue
3
Fibroblast

• Most common in connective tissue
• Synthesize the extracellular matrix and collagen.
  
• Play a critical role in would healing.

Fibroblast
5
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
7
Fat Cells/ Adipose Cells

• Synthesizes and contains large globules of fat
• Also serve as a fuel reserve

8
Mast Cells

• Mediate inflammatory responses such as
  hypersensitivity and allergic reactions
• Store a number of chemical mediators

9
Plasma Cells

• Involved in the synthesis, storage, and release
  of antibodies
• Each cell can secrete several thousand molecules
  of antibodies

10
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 layers Muscles Functions
Nourish nearby epithelial cells Fill spaces
between muscles Binds skin to underlying organs.
12
Adipose Connective Tissue Locations
Joints Some organs ( Kidney, heart) Lower layer
of skin Behind eye balls Functions Cushioning In
sulation Energy storage
13
Hayline Cartilage Locations Ends of bones in
many joints Supporting rings of
trachea Functions Development and growth of
most bones Keep respiratory passageway open
Elastic Cartilage Locations Ears
(External) Larynx Functions Framework for ear
and voicebox.

Fibrocartilage Locations Vertebrae Bones in
the knee Pelvic girdle Functions Shock
absorber, cushions
