Test 5- Reproductive System Flashcards
Encased in tough, white, fibrous CT capsule
Testes
Sac that holds testes outside the body cavity, keeping the temperature at 34C
Scrotum
Cryptorchidism
Testes do not descent into scrotum at the latter part of fetal development
Cone shaped areas that contain interstitial cells and one seminiferous tubule
Lobules
Produce testosterone and androgen
Interstitial cells
Tightly coiled tube in lobule that performs spermatogenesis
Seminiferous tubule
Contains eg penetrating chemicals
Acrosome (head of sperm)
Contains mitochondria that produces energy to run the flagellum
mid sperm
Tail that propels sperm to the ovum in the fallopian tube
flagellum
Formed by the seminiferous tubules join gin together
epididymis
Stores sperm and has muscular walls that move sperm via peristalsis
Epididymis
What does seminal fluid consist of
- liquid of slightly basic pH and fructose
- prostaglandins
- sperm
causes uterus to contact
Prostaglandins
Tube that goes from the epididymis through the spermatic cord through the inguinal canal and over the posterior wall of the bladder
Vas deferens
Has muscular walls to push sperm along via peristalsis during ejaculation
vas deferens
Encloses testicular arteries and veins, nerves, lymphatic vessels and vas deferens
spermatic cord
Spermatic cord passes from the scrotum into the pelvic cavity. Abdominopelvic organs pass through weak spot into scrotum
Inguinal hernia
Posterior to bladder and join with the ejaculatory ducts
seminal vesibles
Short tubes that pass through the prostate gland and going with the urethra
ejaculatory ducts
Produces 30% of seminal fluid, which is somewhat alkaline and helps raise the pH of vagina
Prostate gland
