BIOL 2255 1st EditionExam # 4 Study Guide Duodenum= serous digestion...Jejunum=chemical digestionVagina is innervated by internal pudendal N…All contribute to seminal fluid: bulbourethral, seminel vesicles, prostate gland.. Retroperitoneal=Suprarenal Gland, Abdominal Aorta, Ascending/Descending Colon, Pancreas, Ureters, Kidneys, IVC . Intraperitoneal= Stomach & Spleen, Small Intestine, Cecum, Appendix, Transverse & Sigmoid ColonPeritoneal folds: 2 lateral(covers epigastric A), 2 medial (covers medial umbilica), 1 median umbilical (covers median umbilical) Sinusoid: super leaky capillaries ..Erection=ishiocavernosus MSpermatic Cord Contents: ductus deferens, testicular A, ductus deferens A, pampiniform plexus, genital branch of genitofemoral N (supplies cremaster) Broad lig of uterus. Mesovarian/Mesosalpinx ligaments, contents: ovaries, uterine tube, ovarian AA/VV, suspensory lig. of ovary, ligament of ovary&round ligament. Round ligament of Uterus- through iguinal canal! Temp, regulation= pampiniform plexus, dartos m and cremasteric m Prostate: rich in enzymes Seminal vesicles : fluid for sperm, protein and sugars, 60% of ejaculatory fluid Bulbourethral/Cowpers: neutralizes urinary acids, lubes tip of penis Testis descent: 3mo: migrate to pelvis, 7mo:close to inguinal ring, 3 days later: thru inguinal canal, 8mo: entered scrotum. Gubernaculum= CT, Male:scrotal ligament Female: upperovarian ligament, lower round ligament of uterus. Processus vaginalis= outpouching of peritoneum, Male: tunica vaginalis Female: becomes labia majora. Homologous Structures: clitoris=glans penis, labia majora=scrotum, greater vestibular bulb= bulborethral gland, paraurethral gland= prostate INTERNAL ILIAC V= drains pelvisPEVLIC JOINTS Lumbosacral joints --- Iliolumbar ligament – unites ilia and L5 vertebra Sacrococcygeal joints –reinforces joint: Sacroccygeal ligaments Sacroiliac joints – Between auricular surface of sacrum and ileum, Movement limited, Anterior sacroiliac ligament, Post. sacroiliac ligament, Interosseus sacroiliac ligament. Pubic symphysis – secondary cartilaginous joint, Sacrotuberous ligament & Sacrospinous ligament - allows only limited upward movement Levator ani muscle – forms muscular sling – three parts: Pubococcygeus, Puborectalic, These notes represent a detailed interpretation of the professor’s lecture.
