| lacunar tonsillitis | Inflammation of the mucous membrane lining the tonsillar crypts. (05 Mar 2000) |
| vascular lacuna | <anatomy> The medial compartment beneath the inguinal ligament, for the passage to the femoral vessels; it is separated from the muscular lacuna by the iliopectineal arch. Synonym: lacuna vasorum. (05 Mar 2000) |
|---|---|
| cartilage lacuna | A cavity within the matrix of cartilage, occupied by a chondrocyte. Synonym: cartilage space. (05 Mar 2000) |

| muscular lacuna | The lateral compartment beneath the inguinal (Poupart's) ligament, for the passage of the iliopsoas muscle and femoral nerve; it is separated by the iliopectineal arch from the vascular lacuna. Synonym: lacuna musculorum. (05 Mar 2000) |

| osseous lacuna | A cavity in bony tissue occupied by an osteocyte. (05 Mar 2000) |
| trophoblastic lacuna | One of the spaces in the early syncytiotrophoblastic layer of the chorion before the formation of villi; in human embryos maternal blood enters these spaces by the 10th day; with the differentiation of the chorionic villi they become intervillous spaces, sometimes called intervillous lacunae. (05 Mar 2000) |
| urethral lacuna | One of a number of little recesses in the mucous membrane of the spongy urethra into which empty the ducts of the urethral glands. Synonym: lacuna urethralis, Morgagni's lacuna. (05 Mar 2000) |
