Female reproductive system
(major parts)
Ovaries
oogenesis
uterine (fallopian) tubes
uterus
vagina
vulva (pudendum) or ext. female genitalia
mammary glands
Ovaries
produce secondary oocytes and hormones, including progesterone and estrogens (female sex hormone), inhibin, and relaxin
Ovaries
(location)
one on either side of the uterus
descend to the brim of the sup. portion of the pelvic cavity during the third month of development.
Support (ligaments) of ovaries
Mesovarium
Ovarian ligaments
Suspensory ligaments
Mesovarium
attaches ovaries to broad ligament of uterus
Ovarian ligaments
attach ovaries to uterus
Suspensory ligaments
attach ovaries to pelvic wall
Hilus
Each ovary contains the point of entrance and exit for blood vessels and nerves along which the mesovarium is attached
Germinal epithelium
sprout or bud
a layer of simple epithelium that covers the surface of the ovary. continuous w/ mesothelium that covers the mesovarium
is a misnomer
Tunica albuginea
a whitish capsule of dese, irr. conn. tisure immediately deep to the germinal epithelium
Stroma of ovaries
Cortex
Medulla
Cortex
contains ovarian follicles
Medulla
deep to ovarian cortex
middle layer
Ovarian follicles
consist of oocytes (immature ova) and their surrounding tissues
Primordial follicles
consists of "primary oocytes" and a layer of squamous epithelium epithelial cells
atretic follicles
many primordial follicles degenerate before birth
Primary follicles
consist of "primary oocytes" and a layer of cuboidal epithelial (follicle) cells
Primordial follicles
at puberty, some primordial follicles respond to F.S.H. each month and form primary follicles
Secondary (growing) follicles
consist of "secondary oocytes" and several layers of epithelial (follicular) cells
Vesicular ovarian (graafian) follicles or mature follicles
contain secondary oocytes that will eventually be released
Corpus hemorrhagicum
refers to the blood clot formed within the collapsed graafian follicle
Corpus luteum (yellow body)
secretes hormones
Corpus albicans (white body)
remains of once-functional corpus luteum
Oogenesis
formation of gametes in ovaries
begins in females before they are even born
meiosis takes place and the resulting germ cells undergo maturation
in the ovaries
Oogenesis
(LOCATION)
Oogenesis
(FUNCTION)
Formation and development of female gametes
Primary oocytes
first appear in primordial follicles
Secondary oocytes
are derived from primary oocytes and reporesent the end products of meiosis I (reduction division)
First polar body
derived from primary oocyte
represents discarded genetic material may or may not divide during meiosis II (equatorial division)
Ovum
is derived from primary oocyte
is the mature egg and end product of meiosis II (equatorial division)
Meiosis II
occurs in the secondary oocyte - is initiated - only if sperm penetration occurs
Secondary polar body
derived from the secondary oocyte
is the end product of meiosis II
represents discarded genetic material
Uterine (fallopian) tubes
transports secondary oocytes and fertilized ova from the ovaries to the uterus
Uterine (fallopian) tubes
(LOCATION)
extend laterally from uterus
lies btwn. the folds of broad ligaments of the uterus
Uterine (fallopian) tubes
(LENGTH)
ap. 4"
Structure of Uterine (fallopian) tubes
Infundibulum
Ampulla
Isthmus
Fimbriae
Infundibulum
(Structure)
Infundibulum
funnel shaped porion of each tube is close to the ovary but open to the pelvic cavity
Fimbriae
fringelike projections attached to the lateral end of the ovary
Ampulla
expanded distal end (2/3) of fallopian tube
is usual site of fertilization and zygote formation
Isthmus
part of uterine tube is the more medial, short, narrow, thick-walled portion that joins the uterus
What is the function of the uterine (fallopian tubes)?
transport or movement of secondary oocyte/developing embyro to uterus
based on:
Ciliated columnar and secretory cells of mucosa
Peristaltic contraction of muscularis (middle coat).
Infundibulum
Fimbriae
Ampulla
Isthmus
Uterine (fallopian) tubes structure?
