| lenticular astigmatism | Astigmatism due to defect in the curvature, position, or index of refraction of the lens. (05 Mar 2000) |
| lenticular bone | A knob at the tip of the long limb of the incus which articulates with the stapes. Synonym: processus lenticularis incudis, lenticular apophysis, lenticular bone, orbicular bone, orbicular process, orbiculare, os orbiculare, os sylvii. (05 Mar 2000) |
| lenticular capsule | The capsule enclosing the lens of the eye. Synonym: capsula lentis, crystalline capsule, lenticular capsule, phacocyst. (05 Mar 2000) |
| lenticular colony | A bacterial colony shaped like a lentil or a double-convex lens. (05 Mar 2000) |
| lenticular fasciculus | The pallidal efferent fibres that cross the internal capsule and are insinuated between the subthalamic nucleus and zona incerta; they join in the formation of the thalamic fasciculus. See: lenticular loop. Synonym: fasciculus lenticularis. (05 Mar 2000) |
| lenticular fossa | A depression on the anterior surface of the vitreous body in which lies the lens. Synonym: fossa hyaloidea, lenticular fossa, patellar fossa of vitreous. (05 Mar 2000) |
| lenticular ganglion | <anatomy, neurology> Neural crest derived ganglion acting as relay between parasympathetic neurons of the oculomotor nucleus in the midbrain and the muscles regulating the diameter of the pupil of the eye. (18 Nov 1997) |
| lenticular knife | A scraper resembling a sharp spoon. (05 Mar 2000) |
| lenticular loop | The pallidal efferent fibres curving around the medial border of the internal capsule. Synonym: ansa lenticularis, lenticular ansa. (05 Mar 2000) |
| lenticular nucleus | Lentiform nucleus, the large cone-shaped mass of gray matter forming the central core of the cerebral hemisphere. The convex base of the cone, oriented laterally and rostrally, is formed by the putamen which together with the caudate nucleus composes the striatum; the apical part, oriented medially and caudally, consists of the two segments of the globus pallidus. The nucleus is ventral and lateral to the thalamus and caudate nucleus, from which it is separated by the internal capsule, and together with the caudate nucleus composes the striate body. Synonym: nucleus lentiformis, lenticula. (05 Mar 2000) |
| lenticular papillae | Collections of lymphoid tissue in the mucosa of the pharyngeal part of the tongue posterior to the terminal sulcus collectively forming the lingual tonsil. Synonym: lenticular papillae, lingual follicles. (05 Mar 2000) |
| lenticular process of incus | A knob at the tip of the long limb of the incus which articulates with the stapes. Synonym: processus lenticularis incudis, lenticular apophysis, lenticular bone, orbicular bone, orbicular process, orbiculare, os orbiculare, os sylvii. (05 Mar 2000) |
| lenticular progressive degeneration | <gastroenterology, neurology> An inherited (autosomal recessive) disorder where there is excessive quantities of copper in the tissues, particularly the liver and central nervous system. Wilson's disease causes the body to absorb and retain copper. The copper deposits in the liver, brain, kidneys and eyes. Complications include dementia and liver failure. Symptoms include jaundice, vomiting, tremors, weakness and slow stiff movements. Blood tests show serum ceruloplasmin is low. Medications are given to remove the excess copper from the body. Even with life-long treatment, disabling (and life-threatening) side effects are common. Inheritance: autosomal recessive. (27 Sep 1997) |
| lenticular syphilid | Eruption of flattened, dull reddish papules, 5 mm to 1 cm in diameter, occurring in secondary syphilis. Synonym: flat papular syphilid. (05 Mar 2000) |
