Ureteric plexus

Ureteric Plexus is a network of nerves that supply the ureter, a tube that carries urine from the kidneys to the bladder. The plexus is part of the autonomic nervous system, which controls involuntary body functions.

Etymology

The term "Ureteric Plexus" is derived from the Latin "ureter" meaning "urinary canal" and the Greek "plexus" meaning "braid" or "network".

Anatomy

The Ureteric Plexus is located along the length of the ureter. It is formed by branches from the renal, aortic, and hypogastric plexuses. The nerves in the plexus are primarily sympathetic, but also contain some parasympathetic fibers.

Function

The primary function of the Ureteric Plexus is to control the contraction of the smooth muscle in the walls of the ureter. This contraction, known as peristalsis, helps to move urine from the kidneys to the bladder.

Clinical Significance

Damage or disease affecting the Ureteric Plexus can lead to a variety of urinary disorders. For example, a blockage in the ureter can cause hydronephrosis, a condition in which the kidney becomes swollen due to a buildup of urine. In addition, inflammation of the ureter (ureteritis) can cause pain and other symptoms.
