25
Where does fimbriae at the end of uterine tube open into?
The peritoneal cavity
26
Why is there a possibility of infection transfer from genitals to peritoneal cavity?
Because the fimbrae have an open communication into the peritoneal cavity
27
What hormones do ovaries secrete?
Oestrogen and progesterone
28
What causes ovaries to secrete hormones?
Response to LH and FSH
29
Where is the ovum released by ovary?
Directly into the peritoneal cavity to be picked up by the fimbriae of uterine tube
30
What is the fornix of vagina?
Superior part of vagina where the walls are held apart by the cervix
31
What are the 4 parts of the fornix?
Anterior Posterior 2 x lateral
32
What can be palpated on vaginal digital examination?
Ischial spines (to find pudendal nerve) Position of uterus Adnexae
33
How can the adnexae be palpated?
Place fingers into lateral fornix Press deeply with other hand into iliac fossa of same side Can detect large masses or tenderness
34
What is the perineum?
Shallow space between pelvic diaphragm and skin
35
What are the 2 pouches of perineum?
Superficial | Deep
36
What are the 2 triangles of perineum?
Urogenital | Anal
37
What nerve supplies perineal muscles?
Pudendal nerve
38
What muscle forms the majority of the pelvic diaphragm?
Levator ani
39
What nerve supplies the pelvic diaphragm?
S3, S4, S5
40
Functions of levator ani (3)
1. Support abdominopelvic organs through their tonic contraction 2. Resist any increases in intrapelvic or abdominal pressure during e.g. coughing 3. Urinary and fecal continence
41
What is the perineal body?
Bundle of collagenous and elastic tissue
42
What attaches to perineal body?
Perineal muscles
43
Why is perineal body important?
Pelvic floor strength
44
Where is perineal body located?
Just deep to skin
45
What does perineal body contain?

46
What do Bartholin's glands secrete?
Lubricant for sexual arousal
47
What is anterior to pubic bone?

What does bed of breast lie on?
Deep fasica
51
What muscles does bed of breast cover?
Pec major and serratus anterior
52
Where does retromammary space lie?
Between fascia and breast

56
What is also assessed during a breast examination?
Axilla | Supraclavicular area
57
Where does 75% of lymph from breast drain to?
