Flashcards in Pelvic/Reproductive System Deck (12):
1

What is the function of the pelvis?

-Withstand weight-bearing
-Strength/stability
-Protect organs of reproduction/digestion/urination
-Link trunk/lower limb

2

What are the major bones of the pelvis?

Ilium, Ischium, Pubis

3

What are the joints of the pelvis?

Sacroiliac Joint
-Synovial joints
-Reinforced anteriorly and posteriorly
Pubic Symphysis Joint
-No movement
-Reinforced superiorly and inferiorly

4

What is the difference between male and female pelvic outlets?

Female:
-Childbearing
-Enlarged pelvic outlet
-Broader pubic angle, > 100 degrees
-Less curvature of sacrum and coccyx
-Broader pelvis
-Ilia wider and shorter

5

Describe the kidneys

-Bean shaped
-Regulate electrolytes
-Maintain pH
-Regulate blood pressure by salt: water
-Excrete wastes, e.g urea, ammonium
-Reabsorb water, glucose, amino-acid
-Adrenal glands produce hormones to regulate water and metabolism

6

Describe the ureter

-Hollow muscular tube that transports urine form the renal pelvis to urinary bladder
-Bladder fills= back flow discouraged

7

Describe the urinary bladder

-Smooth muscle walls
-Autonomic control of internal sphincter
-Voluntary control of external sphincter

8

Describe urethra

-Passage of urine and semen (males)

9

What are the muscles of the pelvic diaphragm?

Leavtor Ani and Coccygeus

10

What is the perineum?

-Inferior to pelvic diaphragm between thighs
-Diamond shaped
-Women have 3 outlets, men have 2
-pubic symphysis anteriorly, coccyx posteriorly, ischial tuberosities laterally

11

Describe the pelvic floor

1) Support position of pelvic organs
2) Resists intrabdominal pressure
3) Supports rectum: closes it
4) Made up of muscles

12

Where is the perineum?

The perineum is between the pubic symphysis, two ischial tuberosities and coccyx. It is a diamond shaped area between the legs and is external, or superficial to the pelvic floor.
