Twelve
Twelve (12)
Twelve (pronounced /ˈtwɛlv/), from the Old English twelf, which is of Germanic origin; related to Dutch twaalf and German zwölf, is a number that comes after eleven and before thirteen. In the medical field, the number twelve is significant in several ways.
Anatomy
In human anatomy, there are twelve pairs of ribs in the human body, and twelve cranial nerves that emerge directly from the brain. The duodenum, the first part of the small intestine, is approximately twelve inches long.
Physiology
The human body typically operates on a twelve-hour cycle, with various physiological processes such as temperature regulation and hormone production following this rhythm. This is closely related to the concept of the circadian rhythm, which is approximately 24 hours long and is divided into two twelve-hour periods of day and night.
Medicine
In medicine, the Glasgow Coma Scale is a neurological scale that aims to give a reliable, objective way of recording the conscious state of a person for initial as well as subsequent assessment. A patient is assessed against the criteria of the scale, and the resulting points give a patient score between 3 (indicating deep unconsciousness) and 14 (normal). The twelfth cranial nerve is the Hypoglossal nerve, which controls the movement of the tongue.
Pharmacology
In pharmacology, many medications are designed to be taken every twelve hours to align with the body's natural physiological rhythms. This is particularly common with antibiotics such as Amoxicillin, which is often prescribed to be taken twice a day, twelve hours apart.
