| pleural cavity | The potential space which lies in between the visceral pleura and the parietal pleura. (27 Sep 1997) |
|---|---|
| pleuroperitoneal cavity | That part of the embryonic celom later partitioned to give rise to the pleural and peritoneal cavity's. (05 Mar 2000) |
| cotyloid cavity | <anatomy> The hollow, cuplike portion of the pelvis into which the head of the thigh bone (femur) fits. <zoology> Also, in entomology, the leg socket on an insect's abdomen or thorax. (12 Mar 1998) |
| cranial cavity | <anatomy> The skull. (16 Dec 1997) |
| crown cavity | The space within the crown of a tooth continuous with the root canal. Synonym: cavitas coronalis, cavum coronale. (05 Mar 2000) |
| head cavity | The cephalic region in the embryos of vertebrates containing the modified somites that give rise to the extrinsic eye muscles. (05 Mar 2000) |
| primitive perivisceral cavity | The space between the ectoderm and endoderm in the gastrula. Synonym: primitive perivisceral cavity. (05 Mar 2000) |
| segmentation cavity | The cavity in the blastula of a developing embryo. Synonym: blastocoele, cleavage cavity, segmentation cavity. Origin: blasto-+ G. Koilos, hollow (05 Mar 2000) |
| pulmonary cavity | The portion of the thoracic cavity lying on either side of the mediastinum and occupied by a lung; the space existing when a lung is removed. (05 Mar 2000) |
| pulp cavity | The central hollow of a tooth consisting of the crown cavity and the root canal; it contains the fibrovascular dental pulp and is lined throughout by odontoblasts. Synonym: cavitas dentis, cavity of tooth, cavum dentis. (05 Mar 2000) |
| somite cavity | 1. Protrusion of muscle substance through a rent in its sheath. Origin: myo-+ G. Kele, hernia 2. The small cavity that appears in somites. Synonym: somite cavity. Origin: myo-+ G. Koilia, a cavity (05 Mar 2000) |
| splanchnic cavity | The celom or one of the body cavity's derived from it. Synonym: visceral cavity. (05 Mar 2000) |
| nasal cavity | The proximal portion of the respiratory passages on either side of the nasal septum, lined with ciliated mucosa, extending from the nares to the pharynx. (12 Dec 1998) |
| nephrotomic cavity | 1. Hernial displacement of a kidney. Origin: nephro-+ G. Kele, hernia 2. In lower vertebrates, the developmental cavity connecting the myocele with the celom. Synonym: nephrotomic cavity. Origin: nephro-+ G. Koiloma, a hollow (celom) (05 Mar 2000) |
| subarachnoid cavity | The space between the arachnoidea and pia mater, traversed by delicate fibrous trabeculae and filled with cerebrospinal fluid. Since the pia mater immediately adheres to the surface of the brain and spinal cord, the space is greatly widened wherever the brain surface exhibits a deep depression (for example, between the cerebellum and medulla); such widenings are called cisternae. The large blood vessels supplying the brain and spinal cord lie in the subarachnoid space. Synonym: cavum subarachnoideum, subarachnoid cavity. (05 Mar 2000) |
