Adipose Tissue

Functions of Adipose Tissue

• Energy Storage

  • Stores fat, which is an energy source for organs.
  • Fat has more energy per gram compared to glucose.
  • Efficient way for organisms to store energy.

• Cushioning Organs

  • Cushions organs like eyes, heart, and kidneys.
  • Provides a protective layer around these organs.

• Insulation

  • Helps insulate the body from cold.
  • Found under the skin.

Characteristics of Adipose Cells

• Size and Structure

  • Cells are very large, varying with fat content.
  • Central area of the cell is used for fat storage.
  • Nucleus gets pushed to the side as fat accumulates.

• Arrangement

  • Adipose cells are closer together compared to other connective tissues.
  • Group of adipose cells appears like air bubbles or spaces within the tissue.
  • Visible in micrographs, for example, around the trachea.

Microscopic View

• Micrograph Observations
  • Shows adipose tissue around organs, such as the trachea.
  • Cells can be identified individually; nuclei may not always be visible depending on the sectioning.
  • Centralized fat storage areas are prominent features.

Summary of Functions

• Storing fat (energy source)
• Protecting and cushioning organs
• Insulating the body from cold
