Adipose Tissue

Adipose tissue, also known as fat tissue, is a specialized type of connective tissue that functions to store energy in the form of fat. It is primarily made up of adipocytes, which are cells that specialize in the storage of fat. There are two main types of adipose tissue: white adipose tissue and brown adipose tissue.

White Adipose Tissue:

• White adipose tissue is the most common type of adipose tissue in the body.
• Its primary function is to store energy in the form of triglycerides, which can be broken down to release energy when needed.
• It also acts as a protective cushion around organs and provides insulation to help maintain body temperature.

Brown Adipose Tissue:

• Brown adipose tissue is more metabolically active than white adipose tissue.
• It contains a higher number of mitochondria, which gives it a brown color and allows it to generate heat through thermogenesis.
• Brown adipose tissue is important for maintaining body temperature, especially in newborns and hibernating animals.

Functions of Adipose Tissue:

1. Energy Storage: Adipose tissue stores excess energy in the form of triglycerides, which can be used as a source of fuel when needed.
2. Insulation: The layer of adipose tissue beneath the skin helps to insulate the body and maintain a constant internal temperature.
3. Protection: Adipose tissue acts as a cushion, providing protection for organs against physical trauma.

Study Guide:

1. Describe the structure and function of adipose tissue.
2. Differentiate between white adipose tissue and brown adipose tissue in terms of their structure and function.
3. Explain the role of adipose tissue in energy storage and thermoregulation.
4. Discuss the significance of adipose tissue in the context of obesity and metabolic disorders.
