Origin Of Medical Terms

To understand Medicine you only need to understand how diseases and tissues are named. 

Diseases and body parts are mere descriptions in Latin or Greek. Take Menorrhagia for example. Menos means monthly; rrhag from rhegnunai means "to burst". In other words, excessive monthly flow of blood.

Or consider ENDOMETRIOSIS ("leaking womb"), A condition whereby the lining of the womb (endometrium) is present outside the womb, causing  menstrual, sexual intercourse and abdominal pain. Endo = inside or lining; metra = womb; -osis = disease. So this is a disease due to the lining of the womb!  Compare Tuberculosis (disease caused by the tubercle bacillus) or OSTEOPOROSIS (Brittle bone disease): osteo = bone; poros = pore, passage; osis = disease.

Tissue names are mere descriptions:

Vagina (Latin for sheath or scabbard). It is merely a flap of skin that can stretch to accommodate whatever passes through it - from a small man's tool to a big baby's head during the process of labour.

Cervix - Ever wondered why we have cervical smears AND also, the spine in our neck is called Cervical spine? Cervic=x is latin for "Neck" or the narrow part of something - head, land (channel, isthmus) or womb. Hence the narrow part of the womb is its cervix; the narrow part of our head is its cervix; The bone there is the cervical spine.

Biceps (Latin for "two-headed": bi = two; ceps from caput, as in cephalic = head. The muscle in front of the arm that has two bellies and two heads.
