| musculus gracilis | <anatomy, muscle> Origin, ramus of pubis near symphysis; insertion, shaft of tibia below medial tuberosity (see pes anserinus); action, adducts thigh, flexes knee, rotates leg medially; nerve supply, obturator. Synonym: musculus gracilis, gracilis. (05 Mar 2000) |
| musculus tibialis gracilis | <anatomy, muscle> Origin, lateral supracondylar ridge; insertion, medial margin of tendo achillis and deep fascia of ankle; action, traditionally described as plantar flexion of foot; many investigators now believe the plantaris muscle to be primarily a proprioceptive organ; nerve supply, tibial nerve. Synonym: musculus plantaris, musculus tibialis gracilis, plantar muscle. (05 Mar 2000) |
| nucleus fasciculi gracilis | The medial one of the three nuclei of the dorsal column, the remaining two being the cuneate nucleus and the accessory cuneate nucleus, which corresponds to the clava; it receives dorsal-root fibres conveying sensory innervation of the leg, and lower trunk, and projects, by way of the medial lemniscus, to the ventral nucleus posterior nucleus of the thalamus. Synonym: nucleus gracilis, nucleus fasciculi gracilis, nucleus funiculi gracilis, nucleus of Goll. (05 Mar 2000) |
| nucleus funiculi gracilis | The medial one of the three nuclei of the dorsal column, the remaining two being the cuneate nucleus and the accessory cuneate nucleus, which corresponds to the clava; it receives dorsal-root fibres conveying sensory innervation of the leg, and lower trunk, and projects, by way of the medial lemniscus, to the ventral nucleus posterior nucleus of the thalamus. Synonym: nucleus gracilis, nucleus fasciculi gracilis, nucleus funiculi gracilis, nucleus of Goll. (05 Mar 2000) |

| tubercle of nucleus gracilis | tubercle of gracile nucleus |
| tuberculum nuclei gracilis | tubercle of gracile nucleus |
| Euglena gracilis | <protozoa> Phytoflagellate protozoon of the algal order Euglenophyta (zoological order Euglenida). An elongate cell with two flagella, one emerging from a pocket at the anterior end. The organism exhibits positive phototaxis, determined by a photoreceptive spot on the basal part of the flagellum shaft being shielded by a carotenoid containing stigma (eyespot) in the wall of the pocket. (18 Nov 1997) |
| fasciculus gracilis | The smaller medial subdivision of the posterior funiculus. Synonym: fasciculus gracilis. (05 Mar 2000) |
| funiculus gracilis | gracile fasciculus |
| lobulus gracilis | The anterior portion of the posteroinferior lobule of the cerebellum, the posterior portion being the semilunar lobule inferior; the two correspond to the tuber of the vermis. Synonym: lobulus gracilis, slender lobule. (05 Mar 2000) |
| vagina processus styloidei | A crest of bone (edge of the tympanic portion of the temporal bone) running from the front and medial side of the mastoid process to the spine of the sphenoid; it splits to ensheath the base of the styloid process. Synonym: vagina processus styloidei, vaginal process. (05 Mar 2000) |
| valvula processus vermiformis | A fold of mucous membrane, simulating a valve, sometimes found at the origin of the vermiform appendix. Synonym: Gerlach's valve, valvula processus vermiformis. (05 Mar 2000) |
