SPECIALIZED CONNECTIVE TISSUE

What are the different components of a specialized connective tissue?

• Adipose Tissue

• Cartilage

• Bones

• Blood

It is a Connective tissue in which fat-storing cells or adipocytes predominate

• Adipose Tissue

• Cartilage

• Joints

• Bone

normally represents 15%-20% of the bodyweight in men, and >20% in women

• Cartilage

• Adipose tissue

• Connective tissue

• Epithelial Tissue

These are very large cells derived from mesenchyme and specialized for energy storage in lipid droplet(s) with triglycerides [fat cells]

• FIbroblast

• Osteoclast

• Osteoblast

• Adipocytes

Are supported by reticular fibers, with connective tissue septa dividing the tissue into lobules of various sizes

• Adipose Tissue

• Connective Tissue

• Epithelial tissue

• Cartilage

Adipocytes of white fat are typically very ________ cells, ranging in diameter from ____ to ____ micrometer

• small

  50 to 100

• large

  50 to 100

• small

  50 to 150

• large

  50 to 150

Cells contain primarily one large lipid droplet (they are unilocular), causing the nucleus and remaining cytoplasm to be pushed against the plasmalemma.

• Brown Adipose tIssue

• White Adipose tissue

• Connective tissue

• Cartilage

______________ comprises up to ___% of total body weight in normal (target weight) well-nourished male adults and up to ___% in females but can reach more than ___% in obesity.

It is distributed throughout the body, particularly in the _________ layers of the skin

• Brown Adipose tIssue

  50% 20% 25%

  shallow

• Brown Adipose tissue

  20% 25% 50%

  deep

• White Adipose tissue

  20% 25% 50%

  deep

• White Adipose tissue

  20% 25% 50%

  shallow

Specialized for relatively long-term energy storage

• Brown Adipose tissue

• White Adipose tissue

White adipocytes can store triglycerides derived from three sources:

• Dietary fats brought to the cells via the circulation as chylomicrons

• Lipids synthesized in the liver and transported in blood with very low-density lipoproteins (VLDLs)

• Free fatty acids and glycerol synthesized by the adipocyte
