| conjunctival cul-de-sac | The space formed by the junction of the bulbar and palpebral portions of the conjunctiva, that of the upper lid being the fornix conjunctivae superior and that of the lower lid the fornix conjunctivae inferior. Synonym: fornix conjunctivae, conjunctival cul-de-sac, retrotarsal fold. (05 Mar 2000) |
| conjunctival sac | The space bound by the conjunctival membrane between the palpebral and bulbar conjunctiva; into which the lacrimal fluid is secreted; it opens anteriorly between the eyelids. Synonym: saccus conjunctivae. (05 Mar 2000) |
| cul-de-sac | 1. A blind pouch or tubular cavity closed at one end; e.g., diverticulum; caecum. Synonym: rectouterine pouch. Origin: Fr. Bottom of a sack (05 Mar 2000) |
| cul-de-sac smear | A cytologic specimen of material obtained by aspirating the pouch of Douglas from the posterior vaginal fornix and prepared by smearing, centrifuging, or filtering; used principally for ovarian cancer. (05 Mar 2000) |

| dental sac | Dense fibrous layer formed from mesodermal tissue that surrounds the epithelial enamel organ. The cells eventually migrate to the external surface of the newly formed root dentin and give rise to the cementoblasts that deposit cementum on the developing root, fibroblasts of the developing periodontal ligament, and osteoblasts of the developing alveolar bone.
