| subarachnoid space | 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) |
| subchorial space | The part of the placenta adjacently beneath the chorionic plate; it joins with irregular channels to form the marginal lakes. Synonym: subchorial lake. (05 Mar 2000) |
| subdural space | Originally thought to be a narrow fluid-filled interval between the dural and arachnoid; now known to be an artificial space created by the separation of the arachnoid from the dura as the result of trauma or some ongoing pathologic process; in the healthy state, the arachnoid is attached to the dura and a naturally occurring subdural space is not present. Synonym: spatium subdurale, cavum subdurale, subdural cavity, subdural cleavage, subdural cleft. (05 Mar 2000) |
| subgingival space | The space between the surface of the tooth and the free gingiva. Synonym: sulcus gingivalis, gingival crevice, gingival space, subgingival space. (05 Mar 2000) |
| Nuel's space | An interval in the spiral organ (of Corti) between the outer pillar cells on one side and the phalangeal cells and hair cells on the other. (05 Mar 2000) |
| superficial perineal space | The superficial compartment of the perineum; the space bounded above by the perineal membrane (inferior fascia of the urogenital diaphragm) and below by the superficial perineal (Colles') fascia; it contains the root structure of the penis or clitoris and associated musculature, plus the superficial transverse perineal muscle and, in the female only, the greater vestibular glands. Synonym: spatium perinei superficiale, Colles' space, superficial perineal pouch. (05 Mar 2000) |
| dead space | A cavity, potential or real, remaining after the closure of a wound which is not obliterated by the operative technique. See: anatomical dead space, physiologic dead space. (05 Mar 2000) |
| deep perineal space | The region between the perineal membrane and the endopelvic fascia of the floor of the pelvis occupied by the membranous part of the urethra, the bulbourethral gland (in the male), the deep transverse perineal and sphincter urethrae muscles, and the dorsal nerve and artery of the penis or clitoris. Synonym: spatium perinei profundum, deep perineal pouch. (05 Mar 2000) |
| suprasternal space | A narrow interval between the deep and superficial layers of the cervical fascia above the manubrium of the sternum through which pass the anterior jugular veins. Synonym: Burns' space. (05 Mar 2000) |
| denture space | That portion of the oral cavity which is, or may be, occupied by maxillary and/or mandibular denture(s), the space between the residual ridges which is available for dentures. See: interarch distance. (05 Mar 2000) |
| disk space | On radiographs of the spine, the radiolucent region between each pair of vertebral bodies. (05 Mar 2000) |
| Disse's space | The potential extravascular space between the liver sinusoids and liver parenchymal cells. Synonym: Disse's space. (05 Mar 2000) |
| image space | <microscopy> The space about an optical system each point of which is conjugate to some point in the object space. (05 Aug 1998) |
| quadrangular space | Musculotendinous formation providing passageway for the axillary nerve, posterior humeral circumflex artery and accompanying veins as they run from the axilla to the superior posterior arm; as the neurovascular structures enter the formation anteriorly, it is bounded superiorly by the shoulder joint, medially by the lateral border of subscapularis, laterally by the surgical neck of the humerus, and inferiorly by the tendon of latissimus dorsi; as the vessels exit the formation posteriorly, it is bounded superiorly by the teres minor, medially by the long head of the triceps, laterally by the lateral head of the triceps and inferiorly by the teres major muscle or tendon; as they emerge, most of the neurovascular structures run on the deep surface of the deltoid muscle, which they supply. Synonym: quadrilateral space. (05 Mar 2000) |
