| RA | rectus abdominis |
| TA | transversus abdominis |
| posterior layer of rectus abdominis sheath | The portion of the sheath of the rectus abdominis muscle that lies posterior to the muscle covering only its upper two-thirds; it is formed by contributions from the aponeuroses of the internal oblique and transversus abdominis muscles; its free inferior margin forms the arcuate line; it is deficient below this, the posterior aspect of the muscle being covered only by transversalis fascia and peritoneum. Synonym: lamina posterior vaginae musculi recti abdominis. (05 Mar 2000) |

| transversus abdominis | <anatomy, muscle> Origin, seventh to twelfth costal cartilages, lumbar fascia, iliac crest, and inguinal ligament; insertion, xiphoid cartilage and linea alba and, through the conjoint tendon, pubic tubercle and pecten; action, compresses abdominal contents; nerve supply, lower thoracic. Synonym: musculus transversus abdominis, musculus transversalis abdominis, transverse muscle of abdomen. (05 Mar 2000) |
| fascia triangularis abdominis | <anatomy> A triangular fibrous band extending from the aponeurosis of the external oblique to the pubic tubercle of the opposite side. See: aponeurosis of external abdominal oblique muscle. Synonym: ligamentum reflexum, Colles' ligament, fascia triangularis abdominis, reflex ligament, triangular fascia. (05 Mar 2000) |
| lamina anterior vaginae musculi recti abdominis | The portion of the rectus sheath that lies anterior to the muscle, consisting in its upper two-thirds of contributions from the aponeuroses of the external and internal oblique muscles, and in its lower third (below the arcuralt line) of contributions from the aponeuroses of all three muscles of the anterolateral abdominal wall. Synonym: lamina anterior vaginae musculi recti abdominis. (05 Mar 2000) |
| lamina posterior vaginae musculi recti abdominis | The portion of the sheath of the rectus abdominis muscle that lies posterior to the muscle covering only its upper two-thirds; it is formed by contributions from the aponeuroses of the internal oblique and transversus abdominis muscles; its free inferior margin forms the arcuate line; it is deficient below this, the posterior aspect of the muscle being covered only by transversalis fascia and peritoneum. Synonym: lamina posterior vaginae musculi recti abdominis. (05 Mar 2000) |
| linea arcuata vaginae musculi recti abdominis | A crescentic line, not always clearly defined, which marks the lower limit of the posterior layer of the sheath of the rectus abdominis muscle. Synonym: linea arcuata vaginae musculi recti abdominis, Douglas' line, linea saemicircularis, saemicircular line. (05 Mar 2000) |
| regio | Synonym: region. Origin: L. (05 Mar 2000) |
| regio analis | The posterior portion of the perineal region through which the anal canal opens; bounded by a line through both isehial tuberosities, the sacrotuberous ligaments and the coccyx. Synonym: regio analis, anal region. (05 Mar 2000) |
| regio antebrachialis anterior | The area between the radial and ulnar borders of the forearm anteriorly. Synonym: facies antebrachialis anterior, regio antebrachialis anterior, anterior antebrachial region, anterior surface of forearm, facies anterior antebrachii. (05 Mar 2000) |
| regio antebrachialis posterior | The area between the radial and ulnar borders of the forearm posteriorly. Synonym: regio antebrachialis posterior, facies antebrachialis posterior, posterior antebrachial region, posterior surface of forearm. (05 Mar 2000) |
| regio axillaris | The region of the axilla, including the axillary fossa. Synonym: regio axillaris. (05 Mar 2000) |
| regio brachialis anterior | Area between deltoid region superiorly and anterior region of elbow inferiorly. Synonym: facies brachialis anterior, regio brachialis anterior, anterior surface of arm, facies anterior brachii. (05 Mar 2000) |
| regio brachialis posterior | The back of arm. Synonym: facies brachialis posterior, regio brachialis posterior, posterior brachial region, posterior surface of arm. (05 Mar 2000) |
