| plexus cardiacus | A wide-meshed network of anastomosing cardiopulmonary and splanchnic nerves arising from the afferent and autonomic nerve fibres (sympathetic) and vagus (parasympathetic) nerves, surrounding the arch of the aorta, the pulmonary artery, and continuing to the atria, ventricles, and coronary vessels. Synonym: plexus cardiacus. (05 Mar 2000) |
| plexus cardiacus profundus | The deeper part of the cardiac plexus. Synonym: plexus cardiacus profundus. (05 Mar 2000) |
| plexus cardiacus superficialis | The superficial and smaller subdivision of the cardiac plexus, formed by the left superior cardiac nerves from the left vagus and cervical sympathetic trunk; it is found beneath the aortic arch, between the arch and the bifurcation of the pulmonary trunk. Synonym: plexus cardiacus superficialis. (05 Mar 2000) |
| plexus caroticus communis | An autonomic plexus accompanying the artery of the same name formed by fibres from the middle cervical ganglion. Synonym: plexus caroticus communis. (05 Mar 2000) |
| plexus caroticus externus | An autonomic plexus formed by the external carotid nerves surrounding the artery of the same name, and giving origin to a number of secondary plexus's along the branches of this artery and to branches to the carotid body. Synonym: plexus caroticus externus. (05 Mar 2000) |
| plexus caroticus internus | A venous network around the internal carotid artery in the carotid canal of the temporal bone, connecting with the cavernous sinus and internal jugular vein.

| 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. (12 Dec 1998) |
| plexus choroideus | <radiology> Formed by the invagination of ependyma into ventricles CP of lateral and third ventricles are continuous, extends posteriorly to temporal horn, 3rd and two lateral ventricles continuous at interventricular foramen CP of fourth ventricle is seperate, shape of a T, vertical limb extends from near Magendie's foramen to the fastigium, horizontal limbs project into cerebellopontine angle cisterns the glomus is a localised enlargement of CP, found at the posterior part of the floor of the ventricle (12 Dec 1998) |
| plexus choroideus ventriculi lateralis | The vascular fringe that projects from the choroidal fissure into each lateral ventricle. Synonym: plexus choroideus ventriculi lateralis. (05 Mar 2000) |
