Q

Uterus function

A

Supports development of infant from embryo to neonate

Note: Highly muscular and composed of numerous parts-fundus, body, and cervix. Endometrial lining proliferates and sheds regularly due to the actions of ovarian hormones. Pathway for pain innervation dependent on position relative to pelvic pain line-highly relevant for anesthesia

Q

Labia majora innervation

A

Pudendal nerve, genitofemoral nerve

19
Q

Labia minora function

A

Provides mechanical protection and secretes oils/mucus to protect the clitoris/urethral/vaginal openings

Note: Medial to labia majora-hairless. Surrounds the vestibule of the vagina, where the clitoris, urethral opening, and vaginal opening are located. Corpus spongiosum erectile tissue is deep to these structures

20
Q

Labia Minora blood supply

A

Internal pudendal artery

21
Q

Labia minora innervation

A

Pudendal nerve

22
Q

Clitoris function

A

Sexual arousal, sexual functioning

Note: Female analogue of penis. Made up of only corpus cavernosum (unlike penis which has 3 erectile bodies)-located at anterior apex of labia minora

23
Q

Clitoris blood supply

A

Internal pudendal artery

24
Q

Clitoris innervation

A

dorsal nerve of clitoris (via pudendal nerve)

25
Q

Testis function

A

Produce sperm

26
Q

Testis blood supply

A

Testicular artery

27
Q

Testis innervation

A

Possible vagus innervation and pelvic splanchnic nerves (S2-S4; parasympathetic); thoracic sympathetic chain (T10-T11; sympathetic); sensation pathways: unconcious/reflex (pelvic splanchnic or vagal), pain (sympathetic & genitofemoral nerve)

28
Q

Epididymis function

A

Site of sperm maturation

Note: Lies on posterior testis

29
Q

Ductus deferens function

A

Transports sperm from epididymis of testis to the ejaculatory duct and prostatic urethra

Note:Turns immediately medially when exiting deep ring

30
Q

Ductus deferens blood supply

A

Testicular artery and internal iliac artery

31
Q

Ductus deferens innervation

A

Pelvic splanchnic nerves (S2-4; parasympathetic), Abdominal sympathetic chain (L1-L2; sympathetic); unconcious/reflex (pelvic splanchnic), pain (pelvic splanchnic, genitofemoral)

32
Q

Prostate function

A

Produces components of semen

Note: Surrounds urethra immediately inferior to bladder (prostatic urethra)

33
Q

Prostate blood supply

A

Branches of internal iliac artery to bladder

34
Q

Prostate innervation

A

Pelvic splanchnic nerves (S2-4; parasympathetic), Abdominal sympathetic chain (L1-L2; sympathetic); sensory pathways: unconcious/reflex (pelvic splanchnic), pain (pelvic splanchnic)

35
Q

Seminal vesicle function

A

Produces components of semen

Note: Duct of seminal vesicle joins with ductus deferens to form ejaculatory duct, which exits into the prostatic urethra

36
Q

Seminal vesicle blood supply

A

Branches of internal iliac artery to bladder

37
Q

Seminal vesicle innervation

A

Pelvic splanchnic nerves (S2-4; parasympathetic), Abdominal sympathetic chain (L1-L2; sympathetic); sensory pathways: unconcious/reflex (pelvic splanchnic), pain (pelvic splanchnic)

38
Q

Scrotum function

A

Contains, supports, protects testes

39
Q

Scrotum blood supply

A

Branches of internal pudendal artery

40
Q

Scrotum innervation

A

Genitofemoral nerve, pudendal nerve

41
Q

Penis function

A

Delivery of sperm into vagina, sexual arousal/functioning, elimination of urine

Note: Male analogue of clitoris. Contains 3 erectile bodies (2 corpora cavernosa, corpus spongiosum) which surround urethra. Base of penis is muscular (called the bulb) which contracts during ejaculation

42
Q

Penis blood supply

A

Internal pudendal artery

43
Q

Penis innervation

A

dorsal nerve of clitoris (via pudendal nerve)
