Equilibrium

Equilibrium (medicine)

Equilibrium (pronounced: /ˌiːkwɪˈlɪbriəm/) is a term used in various fields of medicine to describe a state of balance or stability within a biological system. It is derived from the Latin word 'aequilibrium', which means 'equal balance'.

In Physiology

In physiology, equilibrium refers to the body's ability to maintain a stable internal environment, despite changes in external conditions. This is achieved through a process known as homeostasis. For example, the body maintains an equilibrium of various substances in the blood, such as glucose and oxygen, to ensure proper functioning of the body's cells.

In Neurology

In neurology, equilibrium is often associated with the body's sense of balance. This is controlled by the vestibular system, which includes parts of the inner ear and brain that process sensory information involved with controlling balance and eye movements.

In Pharmacology

In pharmacology, equilibrium refers to the state where the rate of drug absorption equals the rate of drug elimination. This is important in determining the therapeutic window and dosage of a drug.
