| fascicular block | A condition based on the concept that the left branch of the bundle of His provides two of three major fascicles of a system of conduction, of which the right bundle branch constitutes the third, for the transmission of the cardiac impulse from the atrium above to the ventricles below the A-V node; block may occur in any or all fascicles, all three together producing complete A-V block. See: hemiblock. (05 Mar 2000) |
|---|---|
| unidirectional block | Block that prevents passage of an impulse when it approaches from one direction but not from the other, as when block in the A-V node prevents anterograde conduction to the ventricles while retrograde conduction to the atria remains intact. (05 Mar 2000) |
| field block | Regional anaesthesia produced by infiltration of local anaesthetic solution into tissues surrounding an operative field. (05 Mar 2000) |
| field block anaesthesia | Conduction anaesthesia in which small nerves are not anaesthetised individually, as in nerve block anaesthesia, but instead are blocked en masse by local anaesthetic solution injected to form a barrier proximal to the operative site. (05 Mar 2000) |
| first degree A-V block | See: atrioventricular block. (05 Mar 2000) |
| fish-block | See Fish-tackle. Source: Websters Dictionary (01 Mar 1998) |
| local nerve block | Infiltration of a local anesthetic around a peripheral nerve so as to produce anesthesia in the area supplied by the nerve. (16 Dec 1997) |
| accessory portion of spinal accessory nerve | <anatomy, nerve> The roots of the accessory nerve which arise from the medulla; the nerve fibres of the cranial root join the intracranial portion of the vagus nerve and are distributed to the pharyngeal plexus, providing the motor innervation of the soft palate (except the tensor veli palati) and the pharynx. Synonym: pars vagalis nervi accessorii, radices craniales, accessory portion of spinal accessory nerve, cranial roots, vagal part of accessory nerve, vagal part. (05 Mar 2000) |
| acute spinal cord compression | <radiology> Signs and symptoms of cord compression show progression within 24 hours or less: pain, weakness, autonomic dysfunction, sensory loss, ataxia Diagnostic considerations: Primary or secondary malignancy of epidural space or vertebrae, Trauma, Inflammatory process, Osteoarthritis REF: MacNeil BJ, Abrams HL. Brigham and Women's Hospital Handbook of Diagnostic Imaging. Chapter 35. (12 Dec 1998) |
| anterior median fissure of spinal cord | A deep median fissure on the anterior surface of the spinal cord. Synonym: fissura mediana anterior medullae spinalis, anteromedian groove, sulcus ventralis. (05 Mar 2000) |
| anterior spinal artery | <anatomy, artery> Origin, intracranial part of vertebral; distribution, spinal cord and pia mater; anastomoses, spinal of intercostal and lumbar arteries. Synonym: arteria spinalis anterior. (05 Mar 2000) |
| anterolateral column of spinal cord | The lateral white column of the spinal cord between the lines of exit and entrance of the anterior and posterior nerve roots. Synonym: funiculus lateralis, anterolateral column of spinal cord, lateral funiculus of spinal cord. (05 Mar 2000) |
| arachnoid of spinal cord | That portion of the arachnoid which lies within the vertebral canal and surrounds the spinal cord and the vertebral portion of the subarachnoid space. It extends from the foramen magnum above to the S-2 vertebral level. Since the spinal cord ends at the L-2 vertebral level, a wide separation occurs between the arachnoid and pia mater, the lumbar cistern, filled with cerebrospinal fluid in which the cauda equina is suspended. Synonym: arachnoidea mater spinalis, spinal part of arachnoid. (05 Mar 2000) |
| ganglia, spinal | Sensory ganglia located on the dorsal spinal roots within the vertebral column. The spinal ganglion cells are pseudounipolar. The single primary branch bifurcates sending a peripheral process to carry sensory information from the periphery and a central branch which relays that information to the spinal cord or brain. (12 Dec 1998) |
| ganglion cells of dorsal spinal root | Pseudounipolar nerve cell bodies in the ganglia of the dorsal spinal nerve roots; the sensory spinal nerves are composed of the peripheral axon branches of these sensory ganglion cell's, whereas the central axon branch of each such cell enters the spinal cord as a component of the dorsal root.
