Q

Male penile nerve involment:
1.Erection
2.Emmision
3.Expulsion.

A

1.Erection parasympathetic nervous system (pelvic splanchnic nerves,S2-S4):
* NO–>Incr cGMP–>smooth muscle relaxation–> vasodilation–> pro-erectile.

*Norepinephrine–>Incr[Ca2+] –>in smooth muscle contraction–> vasoconstriction –>antierectile.

2.Emission—sympathetic nervous system (hypogastric nerve,T11-L2).

3.Expulsion—visceral and somatic nerves (pudendal nerve).

59
Q

Cystadenocarcinomas are common ovarian tumors
that are often bilateral. The serous type occurs more frequently than the mucinous type and is typically unilocular,
whereas mucinous tumors are multilocular. Serous cystadenocarcinomas account for more than half of ovarian cancers. As the name indicates, they are cystic in appearance.
They may be benign, borderline, or malignant. Benign
tumors have a smooth cyst wall with small or absent papillary projections. Borderline tumors have increasing amounts
of papillary projections. Endometrioid tumors resemble
endometrial carcinomas and may arise in foci of endometriosis.

A
60
Q

Immature teratoma

A

-Presence of all mature embryological tissues,except one–>usually is nerual tissues (explains the name).

61
Q

Immature teratoma

CA-125 is specific for what type of ovarian tumor and how is the commonest way to present?

-Where does gonads (both sexes) drain?

A

-Presence of all mature embryological tissues,except one–>usually is nerual tissues (explains the name).

-Epithelial ovarian tumors+ with ascitis

-Para-Aortic lymph nodes–>first site of metastasis of ovarian and testicular cancer. They develop in abdominal cavity.

62
Q

Mitterlschmerz

A

Mittelschmerz is a unilateral, dull achy pain (seldom severe), initiated after rupture of the mature follicle during ovulation in the middle of the menstrual cycle.
The rupture of the mature follicle during ovulation may cause bleeding and release of prostaglandins that, in turn, irritates the peritoneum, causing pain
-Everything else should be normal

63
Q
