What is NOT a general action of hormones?
What is NOT a general action of hormones?
Hormones do not directly increase body temperature. They regulate various physiological functions, but temperature control is primarily managed by the nervous system.
What is the primary function of hormones?
What is the primary function of hormones?
Hormones primarily control metabolism, influencing how the body uses energy and resources.
What is the paracrine effect?
What is the paracrine effect?
Paracrine effects occur when hormones act on neighboring cells within the same organ. This allows for localized regulation of tissue function.

Study Notes
General Actions and Functions of Hormones
- Hormones are chemical messengers that regulate various physiological processes in the body.
- The primary function of hormones is to communicate information between cells, tissues, and organs.
- Hormones can elicit both rapid and long-term responses, influencing growth, metabolism, and homeostasis.
Types of Hormonal Effects
- Autocrine effect: Hormones acting on the same cells that produce them.
- Paracrine effect: Hormones influencing adjacent cells within the same organ.
Hormones and Enzyme Activity
- Hormones can enhance or inhibit enzyme activity, impacting metabolic pathways and cellular functions.
- They typically do this through signaling pathways, which can lead to the activation or inhibition of specific enzymes.
Hormones and the Reproductive System
- Examples of hormones that control the reproductive system include estrogen and testosterone.
- These hormones are crucial for sexual development, reproductive function, and secondary sexual characteristics.
Hormonal Transportation
- The main way hormones are transported in the body is through the bloodstream, allowing for widespread effects on target organs.
- Hormones can be classified as steroid (lipid-soluble) or peptide (water-soluble), impacting their transport and action mechanism.
