Synonym: ramus frontalis arteriae temporalis superficialis. (05 Mar 2000) |
| lesser superficial petrosal nerve | <anatomy, nerve> The parasympathetic root of the otic ganglion, derived from the tympanic plexus; it leaves the tympanic cavity through the canal for the lesser petrosal nerve and passes within the cranium to the sphenopetrosal fissure, or to the foramen ovale, or to the petrosal foramen through which it descends to reach the otic ganglion; conveys presynaptic parasympathetic fibres from the glossopharyngeal nerve concerned with secretomotor innervation of the perotid gland.

| big axillary nodes and normal breasts | <radiology> Consider: lymphoma, leukaemia, rheumatoid arthritis (12 Dec 1998) |
| ranvier's nodes | Regularly spaced gaps in the myelin sheaths of peripheral axons. Ranvier's nodes allow saltatory conduction, that is, jumping of impulses from node to node, which is faster and more energetically favourable than continuous conduction. (12 Dec 1998) |
| mandibular nodes | One of the facial lymph nodes located by the facial artery near the point it crosses the mandible. Synonym: nodus mandibularis, mandibular nodes. (05 Mar 2000) |
| parietal nodes | The lymph nodes draining the walls of the abdomen or of the pelvis. Synonym: nodi lymphatici parietales, parietal nodes. (05 Mar 2000) |
