    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.
