Connective tissue (part 1)

• 1.Spread slide (No. 4) (Drawing)
• 2.Loose CT (No.1) (small intestine)
• 3.Dense CT ( No.14) (finger skin)
• 4.Adipose tissue (No.14/No.6)
• 5.Reticular tissue (No.6) (lymph node)

Classification

• Connective tissue proper
• Loose connective tissue
• Dense connective tissue
• Adipose tissue
• Reticular tissue
• Specialized connective tissue
• Cartilage
• Bone
• Blood

Characteristics

• Fewer cells ,more matrix, more cell types
• No polarization
• Numerous blood vessles
• From mesoderm-mesenchyme
