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
Tube that transports urine from bladder to outside body and semen from ejaculatory duct to outside body
Urethra
Secretes 5% of seminal fluid
Cowper’s gland
Growth of prostate constricts the urethra
BPH
external composure of the penis
2 crop cavernosa
1 corpus spongiosum
Extension of corpus spongiosum that covers the terminal end of the two corpa cavernous at the distal end of the penis
Glans penis
Fold of skin that covers the glans penis
foreskin
Surgical removal or the prepuce
circumcision
Functions in oogenesis and contains eggs within follicles
Ovaries
Number of follicles present at birth and puberty
2,000,000 and 400,000
Ovulation
follicular cell grows and produce fluid inside the folic
the fluid inside the folic causes the follicle to burst and an ovum is released
Trumpet shaped tubes that are connected to the uterus and have cilia on the inner membrane
fallopian tubes
open funnel shaped end of each fallopian tube
infundibulum
finger like projections on the end of the infundibulum
fimbrae
Causes the ovum to move toward the fallopian tube
beating motion of fimbriae and cilia
When zygote implants in the wall of the fallopian tube
ectopic pregnancy
Normal site of zygote implantation
Uterus
3 main parts of uterus
fundus
body
cervix
rounded superior portion where fallopian tubes enter
fundus
main portion of the uterus
body
narrow outlet or neck that projects into the vagina
cervix
3 layers of the uterine wall
endometrium
myometrium
perimetrium
Benign tumors that arise in the myometrium
Uterine fibroids
Portion or all of the uterus is surgically removed
hysterectomy
Endometrium grows on outside of uterus
Endometriosis
Muscular canal lined with mucous membrane
Vagina
pH of the vagina
3.5-4.0
Skin covered fated superficial to the pubic symphysis
mons pubis
2 elongated rounded folds of skin that forms he lateral boundaries of the vulva
labia majora
2 thin fold of skin that lie within the labia majora
labia minora
Analogous with the penis
clitoris
Area where urinary and genital tracts open to the external body
vestibule
