The trigone (also known as the vesical trigone) [1] is a smooth triangular region of the internal urinary bladder formed by the two ureteric orifices and the internal urethral orifice. The area is very sensitive to expansion and once stretched to a certain degree, stretch receptors in the urinary bladder signal the brain of its need to empty.
Trigone may refer to: Trigone of the lateral ventricle; Trigone of the urinary bladder; Hypoglossal trigone; Olfactory trigone; Vagal trigone; Os trigonum, an ...
The neck of the bladder is the area at the base of the trigone that surrounds the internal urethral orifice that leads to the urethra. [5] In males, the neck of the urinary bladder is next to the prostate gland. The bladder has three openings. The two ureters enter the bladder at ureteric orifices, and the urethra enters at the trigone of the ...
Lateral ventricles and horns The lateral ventricles connected to the third ventricle by the interventricular foramina. Each lateral ventricle takes the form of an elongated curve, with an additional anterior-facing continuation emerging inferiorly from a point near the posterior end of the curve; the junction is known as the trigone of the lateral ventricle.
Cystitis glandularis at trigone. Cystitis glandularis is the transformation of mucosal cells lining the urinary bladder. They undergo glandular metaplasia, a process in which irritated tissues take on a different form, in this case that of a gland. [1] The main importance is in the findings of test results, in this case histopathology.
Trigonitis is a condition of inflammation of the trigone region of the bladder. It is more common in women. [1] The cause of trigonitis is not known, and there is no solid treatment. Electrocautery is sometimes used, but is generally unreliable as a treatment, and typically does not have quick results.
In the upper part of the medulla oblongata, the hypoglossal nucleus approaches the rhomboid fossa, where it lies close to the middle line, under an eminence named the hypoglossal trigone. It is a slight elevation in the floor of the inferior recess of the fourth ventricle, beneath which is the nucleus of origin of the twelfth cranial nerve.
The olfactory trigone is a small triangular area in front of the anterior perforated substance. Its apex, directed forward, occupies the posterior part of the olfactory sulcus , and is brought into view by throwing back the olfactory tract .
