Male Essential Organs |
-Testes: produce sperm |
|
|
Male Accessory Organs |
-Ducts -Glands: produce protective and nutrient solution for sperm -External genitals |
3 accessory organs |
|
Testes |
-in scrotum -develop in abdominopelvic cavity then descend into scrotum -interstitial cells produce testosterone |
|
|
Functions of the Testes |
-Production of testosterone -Spermatogenesis: sperm production |
2 functions |
|
Types of Spermatogenesis |
Meiosis: produces 4 spermatids with 23 chromosomes Spermatozoa: mature spermatids |
2 types |
|
Structures of Spermatozoa |
-Head: holds genetic material -Acrosome: contains enzymes to help penetration of egg -Midpiece: contains mitochondria -produces energy for movement |
3 structures |
|
Ducts of Male Reproductive System |
-Epididymis -Vas Deferens -Seminal Vesicle -Ejaculatory Duct |
4 ducts |
|
Epididymis |
-Along the top and behind the testes in the scrotum -Where sperm mature and develop |
|
|
Vas Deferens |
-Receives sperm from epididymis -Joins seminal vesicle to form ejaculatory duct |
|
|
Seminal Vesicle |
-Produces 60% of semen |
|
|
Ejaculatory duct |
passes through prostate |
|
|
Semen |
rich in fructose to provide energy for movement |
|
|
Prostate Gland |
-Male -Shaped like a donut -Urethra passes through -Produces 30% of semen -Activates motility |
|
|
Bulbourethral Gland |
-Resembles a pea -Produces a small amount of semen |
|
|
Genetalia |
Penis and scrotum |
|
|
Female Essential Organs |
Ovaries: produce ova |
|
|
Female Accessory Organs |
-Ducts: fallopian tubes, uterus and vagina -Sex glands: breasts -External genetilia |
3 accessories |
|
Ovaries |
-found in pelvis on either side of uterus -suspended by ligaments called fallopian tubes |
|
|
Ovarian Follicles |
-Contain ooacytes (1 million) -already present @ birth -350 - 500 produced during lifetime menstrual cycles |
|
|
Corpus Luteum |
Forms after ovulation where ovarian follicle was |
|
|
Functions of the Ovaries |
-Oogenesis: meiosis -Production of estrogen and progesterone |
2 functions |
|
Meiosis |
Produces 4 new eggs but only one survives |
|
|
Estrogen |
Development and maintenance of secondary sex characteristics |
|
|
Progesterone |
Stimulates secretory activity of uterine epithelium and helps estrogen initiate mentruation |
|
|
Reproductive Ducts |
-Uterine (fallopian) Tube -Uterus -Vagina |
3 ducts |
|
Fallopian Tubes |
-Extend 10cm from uterus into abdominal cavity -Fimbrae: finger like structures of tubes |
|
|
Uterus |
-Body, fundus, cervix -Just behind bladder -Myometrium: muscle layer -Endometrium: inner tissue layer |
2 layers |
|
Vagina |
Between bladder and rectum |
|
|
Female Reproductive Glands |
-Bartholin's Gland -Breasts |
2 glands |
|
Bartholin's Gland |
-secretes mucous like lubricating fluid -opens between labia minora |
|
|
Breasts |
-AKA mammary glands -over pectoral muscles -size determined by fat quantity -lactiferous ducts drain @ nipple |
|
|
External Female Genitals |
-Vulva -Perineum |
2 genitals |
|
Vulva |
-mons pubis -clitoris -orifice of urethra -bartholin's gland -vagina -labia minora and majora -hymen |
7 parts, name 4 |
|
Perineum |
Between vaginal opening and anus |
|
