  1. Epididymis
    • Receives sperm from testis 
    • Transports sperm to urethra 
    • 3 parts: Head, Body, and Tail
  2. Head of Epididymis
    • Receives sperm from testis
    • Concentrates sperm
  3. Body of Epididymis
    Sperm Maturation
  4. Tail of Epididymis
    Sperm Storage
  5. Spermatic Cord Functions
    • Provide attachment and support of testis to the body 
    • Provide vascular, nervous, and lymphatic connection to body
    • Heat exchange 
    • Pulse pressure eliminator
  6. Spermatic Cord consists of
    • Pampiniform Plexus 
    • Cremaster Muscle 
    • Vas Deferens 
    • Nerves and Lymphatics
  7. Pampiniform Plexus
    • Majority of spermatic cord 
    • Testicular artery 
    • Testicular vein
  8. Functions of Pampiniform Plexus
    • Heat exchange 
    • Hormone exchange
  9. Cremaster Muscle
    • Primary muscle supporting the testis 
    • Striated (skeletal) muscle 
    • Aid in temperature control (blood movement in pampiniform plexus)
  10. Vas Deferens
    • From tail of the epididymis to the urethra 
    • Transport sperm
    • Thick muscular layer: 
    • Nonexcited- steady smooth contractions
    • Excited- increase contractions(strength and number)
  11. Urethra
    Transport of sperm from vas deferens to the outside environment
  12. Glands
    • Produce Seminal Fluid:
    • Aids in transport of sperm through urethra 
    • Adds volume ti ejaculate 
    • Aids in viability/motility in female tract
    • -->Contains hormones that stimulate female contractions
  13. Vesicular Glands (Seminal Vesicles)
    • Paired, lobed glands, by junction of bladder and urethra 
    • Empty into urethra 
    • Add volume to ejaculate
  14. Prostate Gland
    • Variation in shape and location
    • Secrete fluid to clean and lubricate urethra during stimulation
    • Add small amount of volume to semen
  15. Corpus Prostate
    • Lobe of glandular tissue
    • Dog, tom, stallion, boar, bull
  16. Disseminate Prostate
    • Glandular tissue spread along pelvic urethra 
    • Ram, boar, bull
  17. Bulbourethral Glands
    • Paired glands on either side of pelvis urethra 
    • Bull, ram, stallion: smaller
    • Boar: larger
    • Produce viscous secretin that will cause seminal plasma to coagulate following ejaculation
  18. Penis
    • Male organ of copulation 
    • 3 parts: Root, Body(shaft), Glans
    • 2 Types: Fibroelastic, Musculovascular
  19. Body(Shaft) of Penis
    • Makes up most of length
    • Corpus Cavernosum: majority of shaft
    • Corpus Spongiosum: Surrounds urethra
  20. Glans of Penis
    • Terminal portion, deposits sperm in female at copulation 
    • Prepuce(foreskin) - covers and protects glans
  21. Fibroelastic Penis
    • Found in boars, bulls, rams
    • Encased by connective tissue
    • Sigmoid Flexure
  22. Sigmoid Flexure
    • S-shaped configuration of the shaft 
    • Retractor penile muscle 
    • Relaxed state-contracted
    • Excited state-extended, relaxed
  23. Musculovascular Penis
    • Found in stallions, primates, dog, tom
    • not enclosed by connective tissue
    • Large sinusoids that fill with blood
  24. Ischiocavernosus Muscles
    At root of penis
  25. Pelvic Urethral Muscle
    • Surrounds Urethral Muscle 
    • Sperm Transport
  26. Bulbospongiosis
    • Ventral side of shaft 
    • Empties urethra
  27. Goal of Reproduction Steps
    • Sperm production, maturation, transport 
    • Reproductive Behavior 
    • Copulation
    • Ovulation
    • Fertilization 
    • Implantation 
    • Placentation 
    • Gestation 
    • Parturition 
    • Lactation
  28. Sperm Production
    Occurs in the seminiferous tubules in the testes
  29. Sperm Maturation
    Occurs in the body of the epididymis
  30. Sperm Transport
    Occurs in the seminiferous tubules to the oviduct
  31. Reproductive Behavior
    • Vocalization 
    • Locomotion 
    • Mounting
    • Urinating 
    • Standing Estrous
  32. Copulation
    • Way to move sperm from male to female 
    • Penis 
    • Vagina
  33. Ovulation
    • Females have reproductive cyclicity 
    • Ovaries-follicle
  34. Cyclicity
    Release/ovulate one-many oocytes per cycle
  35. Fertilization
    • Spermatazoa and oocyte fuse together
    • Oviduct (ampullary-isthmic junction or ampulla)
  36. Implantation
    • Embryo migrates from oviduct to uterus 
    • Implants into uterine wall
  37. Placentation
    • Embryo builds placenta
    • Uterus 
    • Placenta: organ that transports nutrients and wastes between dam and fetus
  38. Gestation
    • Fetus grows in placenta, attached to uterine wall 
    • Uterus and placenta
  39. Parturition
    • Birthing process
    • Uterus, Vagina, vulva, cervix, vestibule, placenta
  40. Lactation
    • Provides nutrients/immunity to offspring 
    • Mammary gland
  41. Sperm Transport
    • Seminiferous Tubules
    • Rete tubules 
    • Efferent ducts
    • Head
    • Body 
    • Tail 
    • Vas Deferens
    • Urethra 
    • Vagina
    • Cervix
    • Uterus

    • Ampulla
  42. Oocyte Transport
    • Follicle 
    • Infundibulum 
    • Ampulla
  43. Embryo Transport
    • Ampulla
    • Isthmus 
    • Uterus
  44. Fetal Transport
    • Uterus 
    • Cervix 
    • Vagina 
    • Vestibule 
    • Vulva
