| valvula lymphatica | One of the delicate semilunar valves found in lymphatic vessels; they are usually paired and similar in structure to venous valves and occur at close intervals along the vessel wall. Synonym: valvula lymphatica. (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) |
| valvula pylori | A prominent fold of mucous membrane at the gastroduodenal junction overlying the pyloric sphincter. Synonym: pyloric valve, valvula pylori, valvulae pylori. (05 Mar 2000) |
| valvula semilunaris | <anatomy, cardiology> Refers to a type of valve, aortic or pulmonic valves. (27 Sep 1997) |
| valvula semilunaris anterior valvae trunci pulmonalis | Anterior semilunar cusp of the pulmonary valve. (05 Mar 2000) |
| valvula semilunaris dextra valvae aortae | Right semilunar cusp of the aortic valve. (05 Mar 2000) |
| valvula semilunaris dextra valvae trunci pulmonalis | Right semilunar cusp of the pulmonary valve. (05 Mar 2000) |
| valvula semilunaris posterior valvae aortae | Posterior semilunar cusp of the aortic valve. (05 Mar 2000) |
| valvula semilunaris sinistra valvae aortae | Left semilunar cusp of the aortic valve. (05 Mar 2000) |
| valvula semilunaris sinistra valvae trunci pulmonalis | Left semilunar cusp of the pulmonary valve. (05 Mar 2000) |
| valvula semilunaris tarini | A thin sheet of white matter, hidden by the cerebellar tonsil, attached along the peduncle of the flocculus and, at and near the midline, to the nodulus of the vermis; it is continuous caudally with the epithelial lamina and choroid plexus of the fourth ventricle. Synonym: velum medullare inferius, posterior medullary velum, Tarin's valve, valvula semilunaris tarini, velum semilunare, velum tarini. (05 Mar 2000) |
| valvula sinus coronarii | A delicate fold of endocardium at the opening of the coronary sinus into the right atrium. Synonym: valvula sinus coronarii, coronary valve, thebesian valve. (05 Mar 2000) |
| valvula spiralis | A series of crescentic folds of mucous membrane in the upper part of the cystic duct, arranged in a somewhat spiral manner. Synonym: plica spiralis ductus cystici, Amussat's valve, Heister's valve, spiral valve of cystic duct, valvula spiralis. (05 Mar 2000) |
| valvula tricuspidalis | <anatomy> This heart valve, named for its three cusps (leaflets), divides the right atrium and the right ventricle. When the right atrium contracts blood flows through the tricuspid valve into the right ventricle. On closure, the tricuspid prohibits the backflow of blood into the right atrium. (19 Jan 1998) |
| valvula venosa | In the embryo, one of the pair of valves at the opening from the sinus venosus into the right atrium, Synonym: venous valve. (05 Mar 2000) |
