| periarterial plexus of vertebral artery | <anatomy, artery> A plexus of autonomic nerves on the vertebral artery derives from the subclavian plexus. Synonym: plexus vertebralis, vertebral plexus. (05 Mar 2000) |
| choroid plexus | <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) |
