Study Notes
Growth Hormone Overview
- Growth Hormone (GH) is also known as Somatotropin.
- Secreted by somatotrophs, which are specialized cells in the anterior pituitary gland.
Insulin-like Growth Factor-I (IGF-I)
- The primary source of plasma Insulin-like Growth Factor-I (IGF-I) is the liver, which produces IGF-I in response to GH stimulation.
Triglyceride Breakdown
- Growth Hormone (GH) promotes the breakdown of triglycerides in adipose tissue, facilitating lipid mobilization and energy utilization.
Biological Effects of GH
- Growth Hormone binds to specific receptors on target cells, leading to a direct anabolic effect on tissues, influencing growth and metabolism.
