Study Notes
Functions of Hormones
- Hormones play a crucial role in regulating various bodily functions, such as growth, development, and metabolism.
Endocrine vs. Exocrine Glands
- Endocrine glands produce and secrete hormones directly into the bloodstream, affecting distant cells and organs.
- Exocrine glands produce substances that are transported through ducts and released onto a surface or into a body cavity, such as sweat glands or salivary glands.
Study of the Endocrine System
- The study of the endocrine system is called endocrinology.
Hormone Communication
- Hormones communicate with the body by binding to specific receptors on target cells, triggering a response.
Expansion of Endocrinology
- Advances in genetics, molecular biology, and biochemical techniques have contributed to the rapid expansion of the field of endocrinology.
Role of Hormones in the Endocrine System
- Hormones act as chemical messengers, regulating various bodily functions and maintaining homeostasis.
Exocrine vs. Endocrine Glands
- Exocrine glands secrete substances through ducts, whereas endocrine glands secrete hormones directly into the bloodstream.
Medical Practice of Endocrinology
- The practice of medicine related to the study of the endocrine system is called endocrinology.
Hormone Effects on Surrounding Tissues
- In addition to targeting specific cells, hormones can also have a paracrine effect, influencing surrounding tissues and eliciting a response.
Test your knowledge of the endocrine system and hormone function with this quiz. Explore the role of endocrine glands in producing and regulating hormones, and how these chemical messengers impact the body's functions and cells.
