| recessus infundibuliformis | A slitlike depression in the membranous (non-muscular) pharyngeal wall extending posterior to the opening of the auditory (eustachian) tube. Synonym: recessus pharyngeus, recessus infundibuliformis, Rosenmuller's fossa, Rosenmuller's recess. (05 Mar 2000) |

| recessus intersigmoideus | A triangular peritoneal recess behind and below the sigmoid colon created by the attachment of the sigmoid mesocolon ascending across the left psoas then turning sharply to descend into the pelvis; the left ureter (pars tecta ureterica) passes posterior to this recess. Synonym: recessus intersigmoideus. (05 Mar 2000) |
| recessus lateralis ventriculi quarti | The narrow recess of the ventricle that extends laterally over, and down along the side of, the inferior cerebellar peduncle and the overlying cochlear nuclei; at its tip it opens by way of Luschka's foramen into the interopeduncular cistern of the subarachnoid space. By way of this recess, part of the choroid plexus of the fourth ventricle protrudes into the subarachnoid space. Synonym: recessus lateralis ventriculi quarti. (05 Mar 2000) |
| recessus lienalis | The extension of the omental bursa toward the hilum of the spleen. Synonym: recessus splenicus, recessus lienalis. (05 Mar 2000) |
| recessus membranae tympani posterior | A narrow pocket in the tympanic wall between the posterior malleolar fold and the tympanic membrane. Synonym: recessus membranae tympani posterior, Troltsch's pockets, Troltsch's recesses. (05 Mar 2000) |
| recessus membranae tympani superior | A space in the mucous membrane on the inner surface of the tympanic membrane between the flaccid part of the membrane and the neck of the malleus. Synonym: recessus membranae tympani superior, Prussak's pouch, Prussak's space. (05 Mar 2000) |
| recessus opticus | A diverticulum extending forward from the anterior part of the third ventricle above the optic chiasm. Synonym: recessus opticus. (05 Mar 2000) |
| recessus paraduodenalis | An occasional recess in the peritoneum to the left of the terminal portion of the duodenum located behind a fold containing the inferior mesenteric vein. Synonym: recessus paraduodenalis, fossa venosa, paraduodenal fossa. (05 Mar 2000) |
| recessus parotideus | A deep hollow on the side at the sides of the face flanking the posterior aspect of the ramus of the mandible with its attached muscles which is occupied by the parotid gland; it is lined with fascial laminae (the parotid sheath) derived from the investing layer of deep cervical fascia; the structures bounding the space collectively constitute the parotid bed. Surgeons operating in the area take advantage of the fact that the anteroposterior dimensions of the parotid space increase with protrusion of the mandible. Synonym: parotid recess, recessus parotideus. (05 Mar 2000) |
| recessus pharyngeus | A slitlike depression in the membranous (non-muscular) pharyngeal wall extending posterior to the opening of the auditory (eustachian) tube. Synonym: recessus pharyngeus, recessus infundibuliformis, Rosenmuller's fossa, Rosenmuller's recess. (05 Mar 2000) |
| recessus phrenicomediastinalis | The recess of the pleural cavity between the diaphragm and the mediastinum. Synonym: recessus phrenicomediastinalis. (05 Mar 2000) |
| recessus pinealis | A diverticulum from the posterior part of the third ventricle extending back between the posterior commissure and the habenular commissure. Synonym: recessus pinealis. (05 Mar 2000) |
| recessus piriformis | A recess in the anterolateral wall of the nasopharynx on each side of the vestible of the larynx separated from it by the aryepiglottic folds. Synonym: recessus piriformis, piriform recess, piriform sinus. (05 Mar 2000) |
| recessus pleurales | Three recesses of the pleural cavity, one behind the sternum and costal cartilages (costomediastinal recess), one between the diaphragm and chest wall (costodiaphragmatic recess), and one between the diaphragm and mediastinum (phrenicomediastinal recess). Synonym: recessus pleurales, pleural sinuses. (05 Mar 2000) |
| recessus posterior | A deepening of the interpeduncular fossa toward the pons. Synonym: recessus posterior. (05 Mar 2000) |
