13060610778 | pudendal nerve | found 2 cm lateral to anal canal | 154 | |
13060610779 | urachus | structure that joins the apex of the fetal bladder to the ubilicus -after birth is becomes the median umbilical ligament | 155 | |
13060610780 | notable pouches in females and males | males only: - rectovesical: rectum & bladder females: - rectouterine - vesicouterine (pouches caused by uterus draping the peritoneum) | 156 | |
13060610781 | lymph rectum | above pectinate line: - drains inferior mesenteric and internal iliac nodes below pectinate line - cutaneous(skin) region: - flows to *superficial inguinal nodes* (cutaneous portion of anal canal - these nodes would be the first place of metastases) | 157 | |
13060610782 | where do sacral splanchnic nerves come from | sacral sympathetic ganglia & connect to the spinal cord @ level T1-L2 so anesthesia bathing sacral nerve roots would not affect theses nerves | 158 | |
13060610783 | blood supply to the superior portions of the bladder typically arises from the _______ arteries | umbilical (gives off superior vesical arteries which supply superior bladder) >> artery of the ductus deferens in males | 159 | |
13060610784 | pelvic splanchnic nerves primarily carry _____________ to the ___________ plexus | preganglionic parasympathetics inferior hypogastric (all other splanchnic nerves carry sympathetic fibers) | 160 | |
13060610785 | arcus tendineus levator ani is a thickening of fascia of the.... | obturator internus | 161 | |
13060610786 | boundaries of perineum | anterior: pubic symphysis anterolateral: ischiopubic rami lateral: ischial tuberosity posterolateral: sacrotuberous ligament posterior: tip of coccyx | 162 | |
13060610787 | perineal body | irregular fibromuscular mass located at center of posterior border of perineal membrane | 163 | |
13060610788 | artery which supplies blood to major erectile body in both male and female is the | deep artery of the penis/clitoris | 164 | |
13060610789 | four portal - caval anastomoses | hemorrhoids: superior rectal veins (p) & middle and inferior rectal veins (c) esophageal: left gastric vein (p) & azygos (c) caput medusae: paraumbilical veins (p) & veins of anterior abdominal wall draining into IVC 4th: colic veins (p) & retroperitoneal veins (c) | 165 | |
13060610790 | posterior recess | part of the ischioanal (ischiorectal) fossa extending deep to sacrotuberous ligament | 166 | |
13060610791 | main source of blood for superficial palmar arterial arch | ulnar artery (completed on the radial side by the superficial palmar branch of radial artery) radial artery is main source to deep palmar arterial arch (completed by deep branch ulnar) | 167 | |
13060610792 | anatomical snuff box is bounded on ulnar side by tendon of | extensor pollicis longus (radially by tendons of tendons of abductor pollicis longs and extensor pollicis brevis) | 168 | |
13060610793 | muscle tendon which has its own synovial sheath (called radial bursa) in carpal canal | flexor pollicis longus | 169 | |
13060610794 | what is contained in the ulnar bursa | tendons of flexor digitorum profundus and flexor digitorum superficialis | 170 | |

13060610796 | lateral to medial femoral canal | nerve, artery, vein, canal | 172 | |
13060610797 | femoral canal contains | deep inguinal lymph nodes | 173 |
