repo Flashcards
gonads
-primary sex organs
-ovaries/testes
-produce gametes
-secrete steroids
accessory sex organs
-ducts -gamete transport
-glands -fluid secretion
-external genitalia
-organ/tissues involved in embryo nurture
-organs/tissues involved in new-born nurture
seminal vesicles
-produce 70% semen volume [fructose, ascorbic acid, vesiculase [cogulation], prostaglandins]
prostate
-produces 30% semen volume [citrate, enzymes, PSA]
bulbourethral glands
-produces thick clear mucous [lubrication, neutralises residual urine in urethra]
seminiferous tubules
-sperm factories
-immature sperm leave testis via efferent ducts
interstitial cells
-leydig cells
-produce androgens [testosterone]
sperm regions
-head [genetic material, acrosome [contains enzymes required for penetration of oocyte]]
-mid piece [mitochondria]
-tail/flagellum [provides sperm motility]
ovaries
-store eggs
-ovulate one egg per cycle
-produces sex hormones
oviducts
-uterine [fallopian tubes][fimbriae, infundibulum, ampulla, isthmus]
-receive ovulated egg
-site of fertilization
uterus
-site of embryo implantation
-cervix projects into vagina
-perimetrium or serosa [simple squamous epithelium and areolar connective tissue]
-myometrium [longitudinal, circular and oblique layers of smooth muscle]
-endometrium
mammary glands
-15-20 lobes [separated by connective tissue and fat
-lobules [smaller units within lobes, compound alveolar glands that produce milk, pass milk into lactiferous ducts [nipple]]
-lactiferous sinus [dilated region of lactiferous ducts, accumulates milk during nursing]
meiosis produces
haploid cells
hypothalamic-pituitary-gonadal-axis
-hypothalamus secretes gonadotropin releasing hormone [GnRH]
key anterior pituitary gonadotropic hormones
-follicle stimulating hormone [FSH]
-luteinising hormone [LH]
