What is the Origin of Molecular Physiology?

This scientific field emerged as a synthesis of classical physiology and molecular biology, allowing for the precise investigation of biological function beyond the organ and tissue level. It is the language of modern endocrinology, explaining hormone action via receptor-ligand dynamics. The field constantly evolves with advancements in genetic sequencing and protein analysis.

What is the Mechanism of Molecular Physiology?

The core mechanism involves the cascade of events initiated by a molecular signal, such as a hormone binding to its cognate receptor, which then triggers a specific intracellular signaling pathway. This pathway ultimately leads to changes in protein function or gene expression, thereby translating a molecular event into a measurable physiological response at the system level. Understanding this mechanism is vital for targeted drug development.

Molecular Physiology

Meaning

The study of physiological processes at the molecular and cellular level, focusing on the interactions between hormones, receptors, enzymes, and genes that dictate organ function and systemic homeostasis. This discipline provides the foundational biochemical context for understanding human health and disease. It is the language of modern precision medicine and advanced endocrinology.
