Q

What two joints are included in the pelvic girdle?

A

pubic symphysis- secondary cartilagenous joint
—Usually, there are no movements on this joint, except in pregnancy when the ligaments and cartilage soften, allowing the increase of pelvic diameters during labor.

sacroiliac joint- synovial joint
–limited mobility: gliding and rotation; ligaments of the joint soften during pregnancy –> increase of pelvic diameter during childbirth

Q

sacroiliac ligament- interosseous

A

goes between articular surfaces

a short but very strong band that spans the gap between the sacrum and ilium on the posterior side of the joint by attaching to their tuberosities, just behind the auricular surfaces.

roomy cavity
wide, flat sacrum

22
Q

Characteristics of the rectum

A

smooth walls
5 inches long
surrounded by internal and external anal sphincters

vv.- portal system

aa. - inferior mesenteric artery, internal iliac artery

23
Q

What anatomical structure is the urinary bladder directly posterior to?

A

the pubic symphysis

24
Q

What is the retrouterine pouch?

A

An extension of the peritoneal cavity between the rectum and back wall of the uterus. T

25
Q

What is located posterior-superior to the urinary bladder in a female?

A

the uterus

26
Q

puboprostatic ligaments

A

hold and stabilize the prostate against the pubic bone

27
Q

The pelvic floor muscles are just ____ to the prostate in males

A

inferior

28
Q

What is directly posterior to the urinary bladder in males?

A

the rectovesical pouch

29
Q

function of ductus deferens

A

conveys sperm to ejaculatory duct

sperm flows superior to inferior

30
Q

the function of the seminal glands

A

contributes to 85% of ejaculate

coagulating proteins, fructose, prostaglandins, and other specific proteins

31
Q

Where is the ureter in relation to the ductus deferens?

A

The ureter passes directly posterior and inferior to the ductus deferens.

32
Q

The ductus deferens is positioned posterior to the _____

A

bladder

33
Q

Formation of ejaculatory ducts

A

Seminal glands meet with ductus deferens to form ejaculatory ducts within the prostate

34
Q

Function and location of prostate

A

surrounds prostatic urethra

contributes alkaline fluid - the prostate’s primary function is to produce the fluid that nourishes and transports sperm (seminal fluid).

pyramidal fibromuscular gland

‘shape of walnut’

35
Q

Where do the secretions of the bulbourethral glands go?

A

spongy part of urethra

a. They contribute to the final volume of semen by producing a lubricating mucus secretion.

36
Q

4 parts of the urethra:

A

1.) pre-prostatic (at neck of bladder)
2.) prostatic
3.) membranous in the deep transverse perineal musculature
4.) spongy part

37
Q

The function of the bulbourethral glands

A

lubricating function

lubricate the spongy urethra for the passage of the ejaculate. Due to the alkaline pH of the excreted fluid, they also act to neutralize residual acidic urine that remains in the spongy urethra.

small, round, yellow

38
Q

The cervix

A

The lower, narrow end of the uterus (womb) that connects the uterus to the vagina (birth canal).

39
Q

Parts of the uterus

A
  1. Fundus
  2. Corpus - body
  3. Cervix [L. neck]
  4. Internal and external os–> boundaries of the cervix
40
Q

round ligament of the uterus function

A

the round ligament supports and anchors the uterus.

During pregnancy, the round ligaments stretch.

41
Q

Function of the uterine tubes

A

The uterine tubes, also known as oviducts or fallopian tubes, are the female structures that transport the ova from the ovary to the uterus each month.

direct ovocyte from peritoneal cavity to the uterine cavity

42
Q

Ovary

A

female gonads

composed of dense fibrous tissue in which ova are produced and discharged from follicles (ovulation)

size of almond

43
Q

infundibulum function

A

The infundibulum catches and channels the released eggs

44
Q

What is more lateral to the ovary, the ampulla or the isthmus (uterine tube) ?

A

the ampulla

45
Q

The uterus function

A

fetal development and delivery

thick-walled muscular organ

46
Q

broad ligament of the uterus

A

The mesometrium is the mesentery of the uterus. It constitutes the majority of the broad ligament of the uterus, excluding only the portions adjacent to the uterine tube (the mesosalpinx) and ovary (the mesovarium).

47
Q

What is the endometrium of the uterus?

A

uterine lining

48
Q

Function of vagina and termination of vagina:

A

canal for menstrual fluid

inferior part of birth canal

sexual intercourse

cervical canal (start)–> vaginal vestibule (end)

termination of vagina: vaginal vestibule

49
Q

Peritoneal folds/regions of the broad ligament

A

mesosalpinx- closest to the uterine rube

mesovarium- covering the ovary

mesometrium- layer going inferior around the body of the uterus

50
Q

Collateral circulation to the female internal reproductive organs:

A

ovaries- ovarian vessels in ovarian suspensory ligament

uterus-uterine vessels (through broad ligament)

vagina- uterine, vaginal, and internal pudendal vessels

51
Q

Functions of broad ligament of the uterus:

A

supports ovary
supports uterus
passage for blood supply
