Adipose
Definition
Adipose tissue is a type of connective tissue that stores fat and provides cushioning and insulation to the body. It plays a critical role in energy storage and metabolism.
5 Must Know Facts For Your Next Test
- Adipose tissue has two main types: white adipose tissue (WAT) and brown adipose tissue (BAT), with WAT being the primary form in adults.
- White adipose tissue serves as an energy reserve, while brown adipose tissue helps generate heat through non-shivering thermogenesis.
- Leptin, a hormone produced by adipose cells, regulates appetite and energy balance by signaling the brain to reduce hunger.
- Excessive accumulation of white adipose tissue is associated with obesity, which can lead to metabolic disorders such as diabetes and cardiovascular disease.
- Pharmacological agents targeting adipose tissue often aim to enhance lipolysis, reduce fat absorption, or modulate appetite-regulating hormones.
Review Questions
- What are the primary functions of white and brown adipose tissues?
- How does leptin influence appetite and energy balance?
- Why is excessive accumulation of white adipose tissue a concern for health?
