| Savage's perineal body | central tendon of perineum |
| superficial perineal pouch | 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) |

| superficial transverse perineal muscle | <anatomy> An inconstant muscle; origin, ramus of ischium; insertion, central tendon of perineum; action, draws back and fixes the central tendon of the perineum; nerve supply, pudendal (perineal). Synonym: musculus transversus perinei superficialis, superficial transverse muscle of perineum, Theile's muscle. (05 Mar 2000) |
| deep perineal pouch | 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) |

Synonym: spatium perinei profundum, deep perineal pouch. (05 Mar 2000) |
| deep transverse perineal | <anatomy, muscle> Origin, ramus of ischium; insertion, with its fellow in a median raphe; action, assists sphincter urethrae with some sphincteric action on vagina in female; nerve supply, pudendal (dorsal nerve of penis/clitoris). Synonym: musculus transversus perinei profundus, deep transverse muscle of perineum, musculus sphincter vaginae, sphincter vaginae. (05 Mar 2000) |
| transverse perineal ligament | <anatomy> The thickened anterior border of the urogenital diaphragm, formed by the fusion of its two fascial layers. Synonym: ligamentum transversum perinei, Krause's ligament, ligamentum transversum pelvis, transverse ligament of pelvis, transverse ligament of perineum. (05 Mar 2000) |
| anorectal flexure | The anteroposterior curve with convexity anteriorward of the last portion of the rectum. Synonym: flexura perinealis recti, anorectal angle, anorectal flexure. (05 Mar 2000) |
| basicranial flexure | The dorsally concave curvature of the rhombencephalon in the embryo; appearance indicates division of rhombencephalon into myelencephalon and metencephalon. Synonym: basicranial flexure, transverse rhombencephalic flexure. (05 Mar 2000) |
| caudal flexure | The bend in the lumbosacral region of the embryo. Synonym: sacral flexure. (05 Mar 2000) |
| cephalic flexure | The sharp, ventrally concave bend in the developing midbrain of the embryo. Synonym: cerebral flexure, cranial flexure, mesencephalic flexure. (05 Mar 2000) |
| cerebral flexure | The sharp, ventrally concave bend in the developing midbrain of the embryo. Synonym: cerebral flexure, cranial flexure, mesencephalic flexure. (05 Mar 2000) |
| cervical flexure | The ventrally concave bend at the juncture of the brainstem and spinal cord in the embryo. (05 Mar 2000) |
