Celiac Plexus
The celiac plexus, also known as the solar plexus because of its radiating nerve fibers, is a complex network of nerves located in the abdomen, near where the celiac trunk, superior mesenteric artery, and renal arteries branch from the abdominal aorta. It is behind the stomach and the omental bursa, and in front of the crura of the diaphragm, on the level of the first lumbar vertebra. The plexus is formed in part by the greater and lesser splanchnic nerves of both sides, and fibers from the anterior and posterior vagal trunks. The celiac plexus proper consists of the celiac ganglia with a network of interconnecting fibers. The aorticorenal ganglia are often considered to be part of the celiac ganglia, and thus, part of the plexus. Structure The celiac plexus includes a number of smaller plexuses: Other plexuses that are derived from the celiac plexus: Terminology The celiac plexus is often popularly referred to as the solar plexus.

Sympathetic Trunk
The sympathetic trunks (sympathetic chain, gangliated cord) are a paired bundle of nerve fibers that run from the base of the skull to the coccyx. They are a major component of the sympathetic nervous system. Structure The sympathetic trunk lies just lateral to the vertebral bodies for the entire length of the vertebral column. It interacts with the anterior rami of spinal nerves by way of rami communicantes. The sympathetic trunk permits preganglionic fibers of the sympathetic nervous system to ascend to spinal levels superior to T1 and descend to spinal levels inferior to L2/3.Greenstein B., Greenstein A. (2002): Color atlas of neuroscience – Neuroanatomy and neurophysiology. Thieme, Stuttgart – New York, . The superior end of it is continued upward through the carotid canal into the skull, and forms a plexus on the internal carotid artery; the inferior part travels in front of the coccyx, where it converges with the other trunk at a structure known as the ganglion impa ...

Aorticorenal Ganglia
The aorticorenal ganglion is composed of the superior mesenteric, renal, and inferior mesenteric ganglia. This is distinct from the celiac ganglia. However, they are part of the preaortic ganglia. Sympathetic input to the gut comes from the sympathetic chain next to the thoracic vertebrae. The upper nerve supply arrives from cell bodies at the levels of T5–T9, leaves the sympathetic chain by the greater splanchnic nerve, and synapses in the celiac ganglion before proceeding onto the foregut. Below this the lesser splanchnic nerve arises from T10–T11, leaves the sympathetic chain and synapses at the aorticorenal ganglion before going onto also supply the kidney and upper ureter. Below this the least splanchnic nerve arises from T12 and leaves the sympathetic chain to synapse at the "renal plexus The renal plexus is a complex network of nerves formed by filaments from the celiac ganglia and plexus, aorticorenal ganglia, lower thoracic splanchnic nerves and first lum ...

Viscera
In biology, an organ is a collection of tissues joined in a structural unit to serve a common function. In the hierarchy of life, an organ lies between tissue and an organ system. Tissues are formed from same type cells to act together in a function. Tissues of different types combine to form an organ which has a specific function. The intestinal wall for example is formed by epithelial tissue and smooth muscle tissue. Two or more organs working together in the execution of a specific body function form an organ system, also called a biological system or body system. An organ's tissues can be broadly categorized as parenchyma, the functional tissue, and stroma, the structural tissue with supportive, connective, or ancillary functions. For example, the gland's tissue that makes the hormones is the parenchyma, whereas the stroma includes the nerves that innervate the parenchyma, the blood vessels that oxygenate and nourish it and carry away its metabolic wastes, and the conne ...

Getting The Wind Knocked Out Of You
Getting the wind knocked out of you is an idiom that refers to the difficulty of breathing and temporary paralysis of the diaphragm caused by reflex diaphragmatic spasm when sudden force is applied to the upper central region of the abdomen and solar plexus. This often happens in contact sports, from a forceful blow to the abdomen, or by falling on the back. The sensation of being unable to breathe can lead to anxiety and there may be residual pain from the original blow, but the condition typically clears spontaneously in a minute or two. Victims of such a "winding" episode often groan in a strained manner until normal breathing resumes. Loosening restrictive garments and flexing the hips In vertebrate anatomy, hip (or "coxa"Latin ''coxa'' was used by Celsus in the sense "hip", but by Pliny the Elder in the sense "hip bone" (Diab, p 77) in medical terminology) refers to either an anatomical region or a joint.

Superior Mesenteric Plexus
The superior mesenteric plexus is a continuation of the lower part of the celiac plexus, receiving a branch from the junction of the right vagus nerve with the plexus. It surrounds the superior mesenteric artery, accompanies it into the mesentery, and divides into a number of secondary plexuses, which are distributed to all the parts supplied by the artery, viz., pancreatic branches to the pancreas; intestinal branches to the small intestine; and ileocolic, right colic, and middle colic branches, which supply the corresponding parts of the great intestine. The nerves composing this plexus are white in color and firm in texture; in the upper part of the plexus close to the origin of the superior mesenteric artery is the superior mesenteric ganglion.

The spermatic plexus (or testicular plexus) is derived from the renal plexus, receiving branches from the aortic plexus.

Renal Plexus
The renal plexus is a complex network of nerves formed by filaments from the celiac ganglia and plexus, aorticorenal ganglia, lower thoracic splanchnic nerves and first lumbar splanchnic nerve and aortic plexus. The nerves from these sources, fifteen or twenty in number, have a few ganglia developed upon them. It enters the kidneys on arterial branches to supply the vessels, Renal glomerulus, and tubules with branches to the ureteric plexus. Some filaments are distributed to the spermatic plexus and, on the right side, to the inferior vena cava. The ovarian plexus arises from the renal plexus, and is one of two sympathetic supplies distributed to the ovary and fundus of the uterus The uterus (from Latin ''uterus'', plural ''uteri'') or womb () is the organ in the reproductive system of most female mammals, including humans that accommodates the embryonic and fetal development of one or more embryos until birth.
