The spelling of the word "orificium ureteris" is derived from Latin. In IPA phonetic transcription, it is pronounced /ɒrɪfɪsiəm jʊrɪtərɪs/. The word is composed of two parts, "orificium" meaning "opening" and "ureteris" referring to the ureter, which is the tube that carries urine from the kidney to the bladder. Thus, the term refers to the opening of the ureter, which is located in the bladder. This term is commonly used in medical settings to describe conditions and procedures related to the urinary system.
Orificium ureteris is a Latin term commonly used in anatomy and medicine to refer to the opening of the ureter. A more simplified definition of orificium ureteris would be "the mouth or entrance of the ureter."
The ureter is a long, narrow tube that carries urine from the kidneys to the bladder. Each ureter has two openings - one at the upper part of the kidney, known as the renal pelvis, and the other at the bladder. The opening of the ureter at the kidney is called the orificium ureteris superior while the opening at the bladder is referred to as the orificium ureteris inferior or simply orificium ureteris. This particular definition focuses on the latter opening at the bladder.
The orificium ureteris is an essential part of the urinary system as it allows the expulsion of urine from the ureter into the bladder. It is a slit-like orifice that provides a passage for the urine to flow downward, aided by muscular contractions. The location of this opening plays a crucial role in preventing the backflow of urine and maintaining proper urinary function.
Understanding the precise anatomy and function of the orificium ureteris is crucial in diagnosing and treating conditions such as ureteral obstructions, kidney stones, and urinary reflux.
The orifice of the ureter in the bladder, situated one at each upper and outer angle of the trigone, the lower angle being occupied by the internal orifice of the urethra.

The word orificium ureteris is a Latin term. Here is the breakdown of its etymology:
1. Orificium: This comes from the Latin word os meaning mouth or opening and the suffix -ficium indicating a making or giving. Therefore, orificium translates as opening or orifice.
2. Ureteris: This word originates from the Latin word ureter which refers to the ureter, a muscular tube connecting the kidneys to the bladder and transporting urine. The suffix -is indicates the genitive case in Latin, so ureteris means of the ureter.
Consequently, orificium ureteris can be translated as opening of the ureter.
