25
runs the length of the penis to the external urethral orifice
Spongy (penile) urethra
26
Located at the base of the bladder Produce a thick, yellowish secretion (60% of semen)
Seminal vesicles
27
Encircles the upper (prostatic) part of the urethra
Prostate
28
Secretes a milky fluid
Prostate
29
Pea-sized glands inferior to the prostate Produce a thick, clear mucus
Bulbourethral glands
30
Milky white mixture of sperm and accessory gland secretions
Semen
31
Divided sac of skin outside the abdomen that houses the testes Viable sperm cannot be produced at normal body temperature Maintains testes at 3°C lower than normal body temperature
Scrotum
32
Male organ of copulation that delivers sperm into the female reproductive tract
Penis
33
Regions of the penis
Shaft Glans penis (enlarged tip) Prepuce (foreskin)
34
it is also known as Sperm production and begins at puberty and continues throughout life Millions of sperm are made every day
Spermatogenesis
35
Anatomy of the Female Reproductive System
Ovaries Duct system external genitalia
36
Produce eggs (ova) and hormones (estrogen and progesterone)
Ovaries
37
Each ovary houses ovarian follicles consisting of:
Oocyte (immature egg) Follicle cells—layers of different cells that surround the oocyte
38
contains an immature oocyte
Primary follicle
39
growing follicle with a maturing oocyte
Vesicular (Graafian) follicle
40
the follicle ruptures when the egg is mature and ready to be ejected from the ovary; occurs about every 28 days
Ovulation
41
Suspensory ligaments secure the ovaries to the lateral walls of the pelvis
Ovary Support
42
Form the initial part of the duct system Receive the ovulated oocyte from the ovaries Provide a site for fertilization Empty into the uterus Little or no contact between ovaries and uterine tubes Supported and enclosed by the broad ligament
Uterine (fallopian) tubes (continued)
43
also known as the Uterine (fallopian) tube structure
- Infundibulum
44
Fingerlike projections of the infundibulum
Fimbriae
45
Situated between the urinary bladder and rectum Size and shape of a pear, in a woman who has never been pregnant Receives, retains, nourishes a fertilized eggBol
Uterus
46
Broad ligament suspends the uterus in the pelvis Round ligament anchors the uterus anteriorly Uterosacral ligament anchors the uterus posteriorly
Uterine support
47
Regions of the uterus
Body Fundus Cervix
48
Layers of the uterus
Endometrium Myometrium Perimetrium
49
main portion of the uterus
body
50
superior rounded region above where uterine tube enters of the uterus
Fundus
51
narrow outlet that protrudes into the vagina
Cervix
52
Layer of the uterus that: Inner layer (mucosa) Site of implantation of a fertilized egg Sloughs off if no pregnancy occurs (menstruation or menses)
Endometrium
53
is the middle layer of smooth muscle that contracts during labor
Myometrium
54
(visceral peritoneum) is the outermost serous layer of the uterus
Perimetrium
55
Passageway that extends from cervix to exterior of body and is located between urinary bladder and rectum
Vagina
56
The female external genitalia, or vulva, includes:
Mons pubis Labia Clitoris Urethral orifice Vaginal orifice Greater vestibular glands
57
Fatty area overlying the pubic symphysis Covered with pubic hair after puberty
Mons Pubis
58
skin folds of the vagina
Labia
59
Hair-covered skin folds, Enclose the labia minora,Also encloses the vestibule of the vagina
Labia majora
60
delicate, hair-free folds of skin
Labia minora
61
Enclosed by labia majora Contains external openings of the urethra and vagina
Vestibule
62
One is found on each side of the vagina Secretions lubricate vagina during intercourse
Greater vestibular glands
63
Contains erectile tissue Corresponds to the male penis
Clitoris
64
Diamond-shaped region between the anterior ends of the labial folds, anus posteriorly, and ischial tuberosities laterally
Perineum
