What parts are in the pelvic plexus?
The inferior hypogastric plexus (pelvic plexus in some texts) is a network (plexus) of nerves that supplies the organs of the pelvic cavity….
- aorticorenal. Abdominal aortic plexus.
- Superior mesenteric. Gastric.
- Inferior mesenteric. Spermatic.
- Superior hypogastric. hypogastric nerve.
- Inferior hypogastric.
What plexus Innervates the bladder?
bilateral pelvic plexuses
The urinary bladder and urethra require innervation to function effectively. They are innervated via bilateral pelvic plexuses. Part of each pelvic plexus spills onto the caudal bladder as a vesical plexus.
What is pelvic plexus?
The pelvic plexus is an association of neurons that govern visceral tissues involved in eliminative and reproductive functions. It is the singular site in the autonomic nervous system where sympathetic and parasympathetic neurons occur in the same ganglia.
Where is the pelvic plexus located?
rectum
The inferior hypogastric plexus, also known as the pelvic plexus or pelvic ganglion, is a paired collection of nerve fibers situated on each side of the rectum in males, or on sides of the rectum and vagina in females.
What is the lumbosacral plexus?
The lumbosacral plexus is a network of nerves derived from lumbar and sacral roots with each one of them dividing into anterior and posterior branches. Their communications are called lumbar plexus (compare: brachial plexus).
Which nerves contribute to the pelvic plexus?
The pelvic splanchnic nerves contribute parasympathetic efferent fibers to the plexus….Contributions to the inferior hypogastric plexus include:
- superior hypogastric plexus in the form of the hypogastric nerve.
- sacral splanchnic nerves from the sympathetic trunk at vertebral levels T10-L2.
- pelvic splanchnic nerves.
What is mesenteric plexus?
Medical Definition of mesenteric plexus : either of two plexuses of the sympathetic nervous system lying mostly in the mesentery in close proximity to and distributed to the same structures as the corresponding mesenteric arteries: a : one associated with the inferior mesenteric artery.
What plexus drains the bladder?
| Vesical venous plexus | |
|---|---|
| The veins of the right half of the male pelvis. | |
| Details | |
| Drains from | Urinary bladder |

What is a plexus?
A plexus is a bundle of intersecting nerves, blood vessels, or lymphatic vessels in the human body. These bundles typically originate from the same anatomical area and serve specific areas of the body. Bundles of nerves that form a plexus communicate information to your brain about pain, temperature, and pressure.
What is femoral plexus?
The femoral nerve ranks as the largest nerve that arises from the lumbar plexus. It is created from lumbar spinal nerves L2, L3, and L4. Its principal function is to supply motor and sensory innervation to the anterior compartment of the thigh.
What are Nervi Erigentes?
The pelvic splanchnic nerves, also known as nervi erigentes, are preganglionic (presynaptic) parasympathetic nerve fibers that arise from the S2, S3 and S4 nerve roots of the sacral plexus. These nerves form the parasympathetic portion of the autonomic nervous system in the pelvis.
What nerves make up inferior hypogastric plexus?
The inferior hypogastric plexus is formed from the fusion of the superior hypogastric plexus, pelvic splanchnics, and sacral splanchnics incorporated with visceral afferent fibers. Some authors have reported contribution of S1-S5 spinal nerves to the inferior hypogastric plexus.
