Jazmine Mendez P.7 Reproductive System
Major functions of the Reproductive system (male and female)
Gonads: testes and ovaries
Anatomy of male reproductive structures
Ductus (vas) deferens
Urethra
Body of Penis
Gians Penis
Testis
Epididymis
Prostate
Ejaculatory duct
Seminal gland (vesicle)
Bulbo-urethral gland and duct
Ampulla of ductus deferens
Seminiferous tubles
Interstitial cells
Anatomy of female reproductive structures
Hormones of the reproductive system (male and female)
Oogenesis: the process of oocyte production
starts at puberty oocytes stimulate to continue meiosis
Meiosis results in oocytes having half # of chromosomes
egg cell (ovum) and tiny first polar body produce when fertillization occurs and a unequal cytoplasmic division divides
Zygote is the formation fo the end of Meiosis of the chromosomes of the sperm and ovum combine
haploid secondary oocyte and first polar body occurs due to the division of primary occyte under meiosis
Follicle maturation
At puberty, FSH secretion from pituitary increases and cause es ovaries to enlarge
primary follicles are developed by primordial follicles during reproductive years
zona pellucida is clear layer of the primary oocyte
corona radiata is several layers of follicular cells
Primary oocyte +surrounding layer is the egg
Ovulation: process of releasing secondary oocte and polar body from mature antral follicle and surface from ovary
secondary occyte +first polar body
oocyte surrounded by 1-2 layers of follicular cells
brust of LH from anterior pituitary triggers ovulation
oocyte not fertilized within hours it degenerates
Events of the female hormonal cycles
Anterior pituitary gland secretes follicle-stimulating hormone ( FSH ) and luteinizing hormone
FSH stimulates maturation of dominate follicle
Follicular cells become corpus luteum cells that secrete estrogen and progesterone
Follicular cells produce and secrete estrogen
As concentrations of estrogens and progesterone decline, blood vessels in endometrium constrict
Anterior pituitary releases LH that leads to ovulation
Menstrual cycle repeats
uterine lining disintegrates and sloughs off, producing a menstrual flow
Anterior pituitary gland is no longer inhibited and again secretes FSH and LH
If secondary oocyte no fertillized, corpus luteum degenerates and no longer secretes estrogens and progesterone
Disorders associated with the reproductive system (STI)
Methods and classification of contraceptives
