Bulbourethral or Cowper’s glandV. Penis**FEMALE ANATOMY**VI. OvaryVII. Oviduct or Fallopian TubeCurrent Lecture: I. Epididymis: Maturation, Storage, and concentration of sperm cellsA. Capot epididymis: head/fluid absorption occursB. Corpus epididymis: bodyC. Caudal epididymis: tail/sperm area concentrated and storedII. Vas Deferens or Ductus Deferens- Transport of sperm from caudal epididymis to urethra- Ampulla (absent in boar): slow boar ejaculation (5-8 minutes), enlarged portion of vas near urethra/accumulation of sperm prior to ejaculationIII. Urethra- Large muscular canal from bladder through penis - Seminal vesicle and prostate glands empty into the urethra near the junction of the bladder IV. Accessory Sex GlandsA. Seminal Vesicle: secretes fluid (citric acid, fructose, sorbitol) into urethra for the sperm – much larger in boar than other species - Boar: produces most ejaculateo More ova in sow needing fertilization than other speciesB. Prostate Gland: secretes fluid containing buffers and minerals- Small in the bull/absent in the ramC. Bulbourethral or Cowper’s gland: (large in boar)- Empties into urethra away from bladder. Secretes the “gel” fraction to semen that helps seal the cervixV. Penis: copulatory organ/ejaculation of seminal fluid/expulsion of urine- Bull, ram, and boar have fibroelastic peniso S shaped (sigmoid flexure) when released (folds)o Retractor penis muscles: reform s-shape following copulation- Stallion-erection through enlargement with blood/NO sigmoid flexure.VI. Ovary: two main function1. Ova production2. Estrogen and progesterone production- Mature follicle – end of cycle… estrogen- Corpus Luteum (CL)… progesterone VII. Oviduct or Fallopian Tube: transports the ova and sperm/ site of fertilization A. Fimbriae: fringe-like end that covers or partially covers ovary (thin membraneB. Infundibulum: funnel-shaped structure that connects to the ampullaC. Ampulla: fertilization occurs near ampulla: isthmus
