Study Notes
Key Focus of Endocrinology
- Primarily studies the endocrine system, which regulates bodily functions through hormonal signaling.
- Explores the complex interactions between hormones and various bodily processes, including growth, metabolism, and reproduction.
Main Characteristics of Endocrine Glands
- Specialize in producing and releasing hormones directly into the bloodstream.
- Distinct from exocrine glands, which secrete substances through ducts to an external surface.
Definition of Hormones
- Chemical messengers produced by endocrine glands, responsible for regulating physiological activities in the body.
- Target specific organs or cells to elicit specific responses or changes.
Primary System Studied in Endocrinology
- Focuses on the endocrine system within the human body, which includes glands such as the pituitary, thyroid, and adrenal glands.
Characteristics of Hormones' Modes of Action
- Hormones can have widespread effects, influencing multiple tissues and organs simultaneously.
- Mechanisms of action can vary, including altering enzyme activity, gene expression, or cellular metabolism.
