| plexus cervicalis | A network of nerve fibres originating in the upper four cervical spinal cord segments. The cervical plexus distributes cutaneous nerves to parts of the neck, shoulders, and back of the head, and motor fibres to muscles of the cervical spinal column, infrahyoid muscles, and the diaphragm.

| plexus coccygeus | A small plexus formed by the fifth sacral and the coccygeal nerves; it gives origin to the anococcygeal nerves. Synonym: plexus coccygeus. (05 Mar 2000) |
| plexus coeliacus | coeliac (nervous) plexus |
| plexus coronarius cordis | The continuation of the cardiac plexus onto the coronary arteries. Synonym: plexus coronarius cordis. (05 Mar 2000) |
| plexus deferentialis | An autonomic plexus on the seminal vesicle and ampulla of the ductus deferens on each side, derived from the inferior hypogastric plexus. Synonym: plexus deferentialis. (05 Mar 2000) |
| plexus dentalis inferior | Formed by branches of the inferior alveolar nerve interlacing before they supply the teeth; it gives off interior dental branches to the teeth and inferior gingival branches to the gums. Synonym: plexus dentalis inferior. (05 Mar 2000) |
| plexus dentalis superior | Formed by branches of the infraorbital nerve, it gives off superior dental branches to the upper and superior gingival branches to the gums. Synonym: plexus dentalis superior. (05 Mar 2000) |
| plexus entericus | The autonomic plexus in the wall of the intestine; it consists of three parts, submucosal, myenteric, and subserosal; ganglionic cells are scattered through the myenteric and submucosal plexus. Synonym: plexus entericus. (05 Mar 2000) |
| plexus femoralis | An autonomic plexus surrounding the femoral artery, derived from the iliac plexus. Synonym: plexus femoralis. (05 Mar 2000) |
| plexus gangliosus ciliaris | An autonomic plexus lying on the ciliary muscle, derived from the oculomotor, trigeminal, and sympathetic. Synonym: plexus gangliosus ciliaris. (05 Mar 2000) |
| plexus gastrici systematis autonomici | The plexus's along the greater and lesser curvatures of the stomach derived from the coeliac plexus; also known as inferior and superior plexus. Synonym: plexus gastrici systematis autonomici. (05 Mar 2000) |
| plexus gulae | One of two nervous plexus's, posterior and anterior on the walls of the oesophagus; the first is formed by branches from the right vagus and left recurrent, the second by the anastomosing trunks of the vagus after leaving the pulmonary plexus's; branches supply the mucous and muscular coats of the oesophagus. Synonym: plexus oesophageus, plexus gulae. (05 Mar 2000) |
| plexus hepaticus | An unpaired autonomic plexus lying on the hepatc artery and its branches in the liver. Synonym: plexus hepaticus. (05 Mar 2000) |
| plexus hypogastricus inferior | One of the bilateral autonomic plexus in the pelvis distributed to the pelvic viscera; it receives the hypogastric nerves and the pelvic splanchnic nerves. Synonym: plexus hypogastricus inferior, plexus pelvinus, pelvic plexus. (05 Mar 2000) |
| plexus hypogastricus superior | The continuation of the aortic plexus inferior to the aortic bifurcation across the fifth lumbar vertebra into the pelvis where it divides into two hypogastric nerves at the sides of the rectum; these join the pelvic splanchnic nerves to form the inferior hypogastric plexus's supplying pelvic viscera. Synonym: plexus hypogastricus superior, nervus presacralis, Latarget's nerve, presacral nerve. (05 Mar 2000) |
