Tube that carries sperm from the scrotum to the abdominopelvic cavity
Where is the Epididymis found?
Gland located just inferior to the urinary bladder
Portion of the penis containing the urethra
Which of the following is not an accessory gland that contributes fluid to the semen?
A. Bulbourethral gland
B. Prostate Gland
C. Seminal Vesicle
Where sperm is stored
Where do sperm aquire their motility?
Spermatogenisis requires what hormones?
LH, FSH, Testosterone
Erection in the male is controlled by the________ nervous system, while ejaculation is controlled by the ________ nervous system
Superior portion of the uterus
Where are fimbriae found?
The labia minora is part of the:
In a breastfeeding mother, milk is stored In the:
What anchors the uterus to the anterior body wall?
Hormone that stimulates ovulation
LH (luteinizing hormone)
Where fertilization occurs
Immediately after ovulation, estrogen, and progesterone are secreted by the
During part of them normal menstrual cycle, when the levels of progesterone and estrogen decrease, what will occur?
When in the uterine cycle are the progesterone levels the highest?
During the secretory phase
True in both males and female reproductive system
The gametes are formed by meiosis
Areola is an area found on the
A corpus albicans can be found
In the ovary
Which has a very acidic pH out of the Testis,Vagina, Uterus, and ejaculatory duct?
Testes fail to descend
The structure in the female which is homologous to the scrotum
Primary function of the reproduction system
To produce gametes
A mature haploid (male or female) germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote
Single set of unpaired chromosomes
Two complete sets of chromosomes, one from each parent
Testes are housed in the______ which_______.
Scrotum; Lowers sperm development temperature.
What metabolic effect would you expect if someone developed an autoimmune disease in which the person's interstitial cells were destroyed?
Testosterone production would plummet
The______ of a penis fill(s) with blood during arousal causing an erection.
The main sperm carrying duct that deposits sperm into the female reproductive tract
Responsible for producing semen
About how much sperm can be released with each ejaculation
The component in semen that stimulates the uterus to contract in reverse peristalsis
Meiosis results in sperm formation in males. The critical meiotic steps that will ensure proper chromosome number in the resulting offspring is/are__________.
The separation of homologous chromosomes.
The separation of sister chromatids.
Unlike females, males produce gametes throughout life due to the presence of________ in their seminiferous tubes.
Hormones that males secrete
If testosterone were ineffective during development of a males brain, what might be the outcome?
The brain might have female orientation.
Gender identity might be ambiguous.
Houses the oocytes in females
Produce female reproductive hormones
Ovulated oocytes enter the fallopian tubes via________.
Undulations of the fimbriae that draw in the oocytes.
The_______ of the uterus receives the embryo and provides nourishment until the placenta is formed.
The pH of the vagina is normally very acidic, which keeps bacterial growth in check, but the vagina is still home to many bacteria and yeast in balance with each other. Occasionally when a female takes antibiotics for a bacterial infection, a secondary yeast infection results. Why might this happen?
The removal of bacteria from the vagina allows yeast to grow at a faster rate than normal.
In females, the________is the homologous structure to the glans penis in males.
If a non pregnant woman begins taking high levels of progesterone and estrogen supplements followed by high doses of prolactin supplements, what would be the result?
The woman's mammary glands would begin lactating
Risk factors of development of breast cancer
History of no, or short periods of, breast feeding
Early onset of menses and late menopause
Family history of breast cancer
Testis are surrounded by two tunics
Tunica Vaginalis (derived from peritoneum)
Tunica Albuginea (the fibrous capsule)
The blood supplying the Testes comes from________.
The testicular veins and testicular arteries.
What does the spermatic chord enclose?
(all these supply the testes)
Interstitial (Leydig) cells outside the seminiferous tublues produce
Androgens (in males)
Surgical removal of the foreskin
1.) Corpus Spongiosum
2.) Corpora Cavernosa
1.) Surrounds the urethra and expands to form the glans and bulb.
2.) Paired dorsal erectile bodies.
The male duct system
Head: contains efferent tubules
Duct of the epididymis- microvilli absorb testicular fluid and pass nutrients to stored sperm
Non-motile sperm enter, pass slowly through, and become motile
During ejaculation the epididymis contracts, expelling sperm into the ductus deferens.
Ductus deferens and ejaculatory duct
Passes through the inguinal canal
Expands to form the ampulla and then joins the duct of the seminal vesicle to form the ejaculatory duct.
Propels sperm from epididymis to the urethra
Cutting and ligating the ductus deferens, which is nearly 100% effective form of birth control.
Urethra in males
Conveys both urine and semen (at different times)
Has three regions
1) Prostatic urethra
2) Membranous urethra
3) Spongy (penile) urethra
Produces viscous alkaline seminal fluid
Fructose, ascorbic acid, coagulating enzyme(Vesiculase), and prostaglandins
70% of the volume of semen.
Duct of seminal vesicle joins the ductus deferens to form ejaculatory duct.
Bulbourethral glands (Cowper's glands)
Pea-sized glands inferior to prostate
Prior to ejaculation, produces thick, clear mucus
(lubricates glans penis, neutralizes traces of acidic urine in the urethra)
Sequence of events that produces sperm in the seminiferous tubules of the testes.
Is sperm Haploid(n) or Diploid(2n)
Sperm is haploid a single set of 23 chromosomes
