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.
