| filiform pulse | A thready pulse. (05 Mar 2000) |

| filiform | Thread-like. (09 Oct 1997) |
|---|---|
| filiform adnatum | Congenital adhesion of the upper and lower eyelid by bands of tissue. Synonym: filiform adnatum. Origin: ankylo-+ G. Blepharon, eyelid (05 Mar 2000) |
| filiform bougie | A very slender bougie usually used for gentle exploration of strictures or sinus tracts of small diameter where false passages can be encountered or created; the entering end can consist of either a straight or spiral tip, and the trailing end usually consists of a threaded cylinder into which the screw tip of a following bougie can be inserted. (05 Mar 2000) |
| filiform nucleus | A triangular group of large magnocellular neurons in the periventricular zone of the anterior half of the hypothalamus. The cells of the nucleus are similar to those of the supraoptic nucleus; the axons of about 20% of their number join in the formation of the supraopticohypophysial tract and are functionally associated with the posterior lobe of the hypophysis; they project fibres to the brainstem nuclei (dorsal motor nucleus and solitary nucleus) and to the intermediolateral cell column of the spinal cord at thoracic, lumbar, and spinal levels; similar descending autonomic fibres arise from the lateral and posterior hypothalamic nuclei. Synonym: nucleus paraventricularis, filiform nucleus, nucleus filiformis. (05 Mar 2000) |
| filiform papillae | Curved tapering cone shaped body on the tongue of rodents, of which the epithelial cell columns have been investigated in detail. (18 Nov 1997) |
| filiform polyposis | <radiology> Benign, non-specific sequela of diffuse, severe mucosal inflammation, UC, Crohn's, XR: thin, straight filling defects, resembles stalks of polyps without heads (12 Dec 1998) |
| filiform wart | A wart composed of a single or many greatly elongated papillae; appears more commonly on the face and neck. Synonym: filiform wart. (05 Mar 2000) |
| abdominal pulse | The soft, compressible aortic pulse occurring in certain abdominal disorders. Synonym: pulsus abdominalis. (05 Mar 2000) |
| alternating pulse | Mechanical alternation, a pulse regular in time but with alternate beats stronger and weaker, often detectable only with the sphygmomanometer and usually indicating serious myocardial disease. Synonym: pulsus alternans. (05 Mar 2000) |
| amplitude of pulse | See: average pulse magnitude, peak magnitude. (05 Mar 2000) |
| anacrotic pulse | A pulse wave showing one or more notches or indentations on its rising limb that are sometimes detectable by palpation. Synonym: pulsus anadicrotus. (05 Mar 2000) |
| asynchronous pulse generator | A generator in which the rate of discharge is independent of the natural activity of the heart. Synonym: fixed rate pulse generator. (05 Mar 2000) |
| atrial synchronous pulse generator | A ventricular stimulating pulse whose rate of discharge is directly determined by the atrial rate. Synonym: atrial triggered pulse generator. (05 Mar 2000) |
| atrial triggered pulse generator | A ventricular stimulating pulse whose rate of discharge is directly determined by the atrial rate. Synonym: atrial triggered pulse generator. (05 Mar 2000) |
| average pulse magnitude | <physics> The amplitude of pulse averaged throughout its duration; identical with peak amplitude for a square wave or pulse without droop. (05 Mar 2000) |
