| fibrous ring of intervertebral disc | The ring of fibrocartilage and fibrous tissue forming the circumference of the intervertebral disc; surrounds the nucleus pulposus, which is prone to herniation when the annulus fibrosus is compromised. Synonym: annulus fibrosus disci intervertebralis, annulus fibrosus, fibrous ring of intervertebral disc, fibrous ring. (05 Mar 2000) |

| fibrous sheaths | See: fibrous tendon sheath, fibrous digital sheaths of hand, fibrous digital sheaths of foot. (05 Mar 2000) |
| fibrous skeleton of heart | A complex framework of dense collagen forming four fibrous rings (annuli fibrosi), which surround the ostia of the valves, a right and left fibrous trigone, formed by connecting the rings, and the membranous portions of the interatrial and interventricular septa; it is found in association with the base of the ventricles, i.e., at the level of the coronary sulcus; its functions include: 1) contributing reinforcement of the valvular ostia while providing attachment for the leaflets and cusps of the valves; 2) providing origin and insertion for the myocardium; and 3) serving as a sort of electrical "insulator," separating the electrically conducted impulses of the atria and ventricles and providing passage for the common atrioventricular bundle of conductive tissue through the right fibrous trigone and membranous interventricular septum. Synonym: cardiac fibrous skeleton, cardiac skeleton, skeleton of heart. (05 Mar 2000) |
| fibrous tissue | Although most connective tissue has fibrillar elements, the term usually refers to tissue laid down at a wound site well vascularised at first (granulation tissue) but later avascular and dominated by collagen rich extracellular matrix, forming a scar. Excessive contraction and hyperplasia leads to formation of a keloid. (18 Nov 1997) |
| fibrous trigones of heart | See: right fibrous trigone, left fibrous trigone. (05 Mar 2000) |
| fibrous tubercle | A tubercle in which fibroblasts proliferate about the periphery (and into the cellular zones), eventually resulting in a rim or wall of cellular fibrous tissue or collagenous material around the tubercle. (05 Mar 2000) |
| fibrous tunic of corpus spongiosum | <anatomy> The thick layer of fibrous tissue surrounding the corpus spongiosum penis. It is thinner than the corresponding layer around each corpus cavernosum. Synonym: tunica albuginea corporis spongiosi, fibrous tunic of corpus spongiosum. (05 Mar 2000) |
| fibrous tunic of eye | The outer layer of the eyeball composed of the sclera and cornea. Synonym: tunica fibrosa bulbi, tunica externa oculi. (05 Mar 2000) |
| fibrous union | Union of fracture by fibrous tissue. See: nonunion. Synonym: faulty union. (05 Mar 2000) |
| fibrous xanthoma | <tumour> A fibrohistiocytic neoplasm. (05 Mar 2000) |
| lateral column of spinal cord | A slight protrusion of the gray matter of the spinal cord into the lateral funiculus of either side, especially marked in the thoracic region where it encloses preganglionic motor neurons of the sympathetic division of the autonomic nervous system; it corresponds to the lateral horn appearing in transverse sections of the spinal cord. See: gray columns. Synonym: columna lateralis, lateral column of spinal cord. (05 Mar 2000) |
| lateral cord of brachial plexus | In the brachial plexus, the bundle of nerve fibres formed by the anterior divisions of the superior and middle trunks which is located lateral to the axillary artery. This cord gives off the lateral pectoral nerve and terminates by dividing into the musculocutaneous nerve and the lateral root of the median nerve. Synonym: fasciculus lateralis plexus brachialis. (05 Mar 2000) |
| lateral funiculus 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) |
| left fibrous trigone | The part of the fibrous skeleton of the heart located in the interval between the left side of the left atrioventricular ring and the aortic ring. Synonym: trigonum fibrosum sinistrum. (05 Mar 2000) |
| lumbar cord | That part of the cord that consists of the five lumbar segments and gives rise to the five pairs of lumbar nerves. Synonym: pars lumbalis medullae spinalis. (05 Mar 2000) |
