Q

how many layers of the vaginal wall

A

The vaginal walls have three layers

  1. The inner lining, or vaginal mucosa
  • can be seen by opening the labia minora
  • mucous membrane similar to the skin that lines the inside of the mouth
  • feels fleshy, soft, and corrugated
  • may vary from very dry (especially if the woman is anxious about something, such as exams) to very wet
  1. The middle layer of the vaginal wall is muscular.
  2. The outer or deeper layer
    * a fibrous covering that connects the vagina to other pelvic structures.

A
  • small pair of glands that lie to the right and left of the vagina
  • function is unknown, may contribute to vaginal lubrication just before orgasm
  • vestibular bulbs of the clitoris have erectile tissue similar to the spongy bodies of the penis

Q

the G-spot

A
  • the Grafenberg spot
  • a large area located on the front vaginal wall

Q

the ovaries

A
  • two ovaries at the end of the fallopian tubes on each side of the uterus
  • endocrine glands that produce both estrogrens and progestins
  • usually a woman ovulates an ova (egg) alternately from one ovary then the other

Q

Uterus

A

3 layers

  1. Endometrium
  • innermost layer
  • shed during menstruation
  1. Myometrium
  • muscular
  • middle layer
  1. Perimetrium
    * smooth outer layer
18
Q

cancer of the cervix

A
  • 3rd most common form of cancer
  • cause: human papilloma virus
  • if detected early, is curable
  • Pap test: highly accurate test
  • hysterectomy sometimes used as treatment
19
Q

HPV

A

Girls and Women

  • HPV2 vaccine is indicated in females 9 to 45 years of age for the prevention of cervical cancer
  • HPV4 and HPV9 vaccines are for the prevention of the following diseases:

In females 9 to 45 years of age

  • Cervical, vulvar, vaginal cancers and pre-cancerous lesions

In females 9 to 26 years of age

  • Anal cancer and pre-cancerous lesions

Boys and Men

  • HPV4 and HPV9 vaccines are indicated in all males 9 to 26 years of age for the prevention of anal cancers, pre-cancerous lesions and AGWs
  • HPV2 vaccine is not indicated in males at this time.
20
Q

HPV vaccines are not indicated in

A

HPV vaccines are not indicated in:

females or males < 9 years of age

  • as no immunogenicity or efficacy data are available in these groups
21
Q

The fallopian tubes

A
  • the two oviducts or uterine tubes that carry the ova from the ovaries to the uterus
  • 10 cm long, on either side of the uterus
  • fertilization occurs in the infundibulum or part of the tube closest to the ovary
22
Q

Male external organs

A

consist of:

  • the penis
  • scrotum with testes inside
23
Q

the penis

A

Functions:

  • sexual pleasure
  • urination
  • reproduction

Sections of the penis

  • the root: base of penis, extends into the pelvis, attached to the pelvic bones by leg-like structures called crura
  • the shaft: body of the penis, free swinging
  • the glans

The most sensitive area

  • the glans at the head of the penis

contains no bones or muscles, made up of 3 cylindrical spongy bodies

24
Q

the copora cavernosa

A
  • two cylinders covered with a fibrous sleeve that pulls tight when filled with blood and stiffens the penis
  • The two larger cylinders
  • lie side by side
  • function like the cavernous bodies in the clitoris, filling with blood and stiffening during sexual arousal
25
Q

corpus spongiosum

A
  • cylinder that remains soft and spongy during an erection
  • the spongy body
  • runs along the lower (ventral) surface of the penis
26
Q

the scrotum

A

made up of two layers

  1. outer layer: a little hair
  2. inner layer: involuntary muscle called dartos
  • since the testes were formed in the abdomen, they respond to injury or compression like other innervated abdominal tissue
  • thus an injury in the scrotum is felt deep in the abdominal cavity.
27
Q

dartos

A
  • inner layer of involuntary muscle of the scrotum
  • makes the testes contract with cold
28
Q

the testes

A
  • male reproductive organs that secrete male sex hormones (androgens) and produce sperm
  • spermatic cord suspends each testis in the scrotum and contains the vas deferens, blood vessels, and nerves
  • surrounded by layer of muscle called the cremaster muscle that lifts the testicles as they contract
29
Q

the seminiferous tubules

A
  • live inside the testes
  • along with the interstitial cells, produce and store sperm
30
Q

the epididymis

A
  • covers part of each testicle
  • matures and stores sperm
31
Q

vas deferens

A
  • carries sperm to the prostate gland where they enter the urethra
32
Q

the seminal vesicles

A
  • contribute up to 70% of the ejacuate fluid
33
Q

the prostate gland

A
  • secretes a thick, milky, alkaline fluid
  • resulting in a chemically safe environment to maintain sperm
34
Q

cowper’s glands

A
  • secrete a pre-ejaculate fluid (pre-cum) that prepares the urethra for the ejaculate
35
Q

semen

A
  • made up of fluid from the seminal vesicles and the prostate gland
  • each ejaculate contains about 1 teaspoon of semen
  • 200-500 million sperm
  • each sperm has 23 chromosomes
36
Q

Circumcision

A
  • surgical cutting away or removal of the foreskin
  • originally done for cultural and religous reasons
  • world: 30% of men
  • canadian medicare does not cover
37
Q

Phimosis

A
  • condition in which the foreskin of the penis cannot be pulled back past the glans
38
Q

Pros of male circumcision

A
  • decrease in infant UTIs
  • decrease in some STI’s (HIV and genital warts)
  • decrease in adult penile cancer
  • prevents or corrects phimosis
39
Q

Cons of male circumcision

A
  • procedure entails risks such as infection, hemorrhage, shock, and penile mutilation
  • heightened pain response to vaccinations
  • current studies at McGill report no differences in penile sensitivity or arousal response in circumcised or uncircumcised males
40
Q

testicular cancer

A
  • a disease of young men
  • first sign: painless lump in the testes, or slight enlargement or change in consistency of the testes, pain in the lower abdomen or groin
  • diagnosis: physician exam or testicular self-exam and ultrasound
  • cause: unknown
