Temperature maintenance in infants is the function of  

Options

A. White adipose tissue
B. Brown adipose tissue
C. Yellow adipose tissue
D. None

Answer

**Step-by-Step Solution:**

1. **Understanding Adipose Tissue**: Adipose tissue is a type of connective tissue in the body that stores fat and serves several important functions, including insulation and energy storage.

2. **Types of Adipose Tissue**: There are different types of adipose tissue, primarily white adipose tissue and brown adipose tissue. White adipose tissue is mainly for energy storage, while brown adipose tissue is involved in thermogenesis (heat production).

3. **Function of Brown Adipose Tissue**: Brown adipose tissue, also known as brown fat, is specialized for heat generation. It contains a high number of mitochondria, which allow it to burn calories and produce heat, especially in response to cold temperatures.

4. **Importance in Infants**: In infants, brown adipose tissue is particularly important as it helps maintain body temperature. Infants have a higher percentage of brown fat (about 5% of their body mass) compared to adults, which is crucial for thermoregulation.

5. **Mechanism of Action**: When the body temperature of an infant drops below a certain threshold, brown adipose tissue activates and generates heat to help maintain the infant's body temperature.

6. **Conclusion**: Therefore, the correct answer to the question "Temperature maintenance in infants is the function of" is **brown adipose tissue**.

**Final Answer**: Brown adipose tissue
