Bowman's space  capsular s.

bregmatic space  the anterior fontanelle, situated at the junction of the frontal, coronal, and sagittal sutures.

capsular space  a narrow chalice-shaped cavity between the glomerular and capsular epithelium of the glomerular capsule of the kidney.

cartilage spaces  the spaces in hyaline cartilage containing the cartilage cells.

cupular space  the part of the attic above the malleus.

danger space  a subdivision of the retropharyngeal space, extending from the base of the skull to the level of the diaphragm; it provides a route for the spread of infection from the pharynx to the mediastinum.

dead space 

1. the space remaining after incomplete closure of surgical or other wounds, permitting accumulation of blood or serum and resultant delay in healing.

2. in the respiratory tract: (1) anatomical dead s., those portions, from the nose and mouth to the terminal bronchioles, not participating in oxygen–carbon dioxide exchange, and (2) physiologic dead s., which reflects nonuniformity of ventilation and perfusion in the lung, is the anatomical dead space plus the space in the alveoli occupied by air that does not participate in oxygen–carbon dioxide exchange.

epidural space  the space between the dura mater and the lining of the vertebral canal.

episcleral space  the space between the bulbar fascia and the eyeball.

haversian space  see under canal.

iliocostal space  the area between the twelfth rib and the crest of the ilium.

intercostal space  the space between two adjacent ribs.

interglobular spaces  small irregular spaces on the outer surface of the dentin in the tooth root.

interpleural space  mediastinum.

interproximal space  the space between the proximal surfaces of adjoining teeth.

intervillous space  the space of the placenta into which the chorionic villi project and through which the maternal blood circulates.

Kiernan's spaces  the triangular spaces bounded by invaginated Glisson's capsule between the liver lobules, containing the larger interlobular branches of the portal vein, hepatic artery, and hepatic duct.

lymph space  any space in tissue occupied by lymph.

Meckel's space  a recess in the dura mater which lodges the gasserian ganglion.

mediastinal space  mediastinum.

medullary space  the central cavity and the intervals between the trabeculae of bone which contain the marrow.

palmar space  a large fascial space in the hand, divided by a fibrous septum into a midpalmar and a thenar space.

parasinoidal spaces  lateral lacunae.

perforated space  see under substance.

periaxial space  a fluid-filled cavity surrounding the nuclear bag and myotubule regions of a muscle spindle.

perilymphatic space  the fluid-filled space separating the membranous from the osseous labyrinth.

perineal spaces  spaces on either side of the inferior fascia of the urogenital diaphragm, the deep between it and the superior fascia, the superficial between it and the superficial perineal fascia.

periplasmic space  a zone between the plasma membrane and the outer membrane of the cell wall of gram-negative bacteria.

perivascular spaces  spaces, often only potential, that surround blood vessels for a short distance as they enter the brain.

perivitelline space  a space between the oocyte and the zona pellucida.

pneumatic space  a portion of bone occupied by air-containing cells, especially the spaces constituting the paranasal sinuses.

Poiseuille's space  that part of the lumen of a tube, at its periphery, where no flow of liquid occurs.

Reinke's space  a potential space between the vocal ligament and the overlying mucosa.

retroperitoneal space  the space between the peritoneum and the posterior abdominal wall.

retropharyngeal space  the space behind the pharynx, containing areolar tissue.

retropubic space  the areolar space bounded by the reflection of peritoneum, symphysis pubis, and bladder.

Retzius space 

1. retropubic s.

2. perilymphatic s.

subarachnoid space  the space between the arachnoid and the pia mater.

subdural space  the space between the dura mater and the arachnoid.

subgingival space  gingival crevice.

subphrenic space  the space between the diaphragm and subjacent organs.

subumbilical space  a somewhat triangular space in the body cavity beneath the umbilicus.

Tenon's space  episcleral s.

thenar space  the palmar space lying between the middle metacarpal bone and the tendon of the flexor pollicis longus.

zonular spaces  the lymph-filled spaces between the fibers of the ciliary zonule.
