Q

What is the bulb of the vestibule?

A

Erectile tissue that flanks the vestibule

18
Q

What muscle covers the bulb of the vestibule?

A

the bulbospongiosus muscle

19
Q

What provides parasympathetic innervation of erectile tissue?

A

the pelvic splanchnic nerves (S2-S4)

20
Q

What is the function of the Greater vestibular glands (Bartholin glands)?

A

To secrete mucus into the vestibule to lubricate the vagina during sexual arousal

21
Q

What innervates the female perineal muscles?

A

perineal nerve branches of the pudendal nerve

22
Q

What does the ischiocavernosus muscle surround in female anatomy?

A

the crus and corpus cavernosum of the clitoris

23
Q

What is the primary function of the Superficial transverse perineal muscle?

A

to support the perineal body

24
Q

What is the perineal body?

A

A fibromuscular mass located in the center of the perineum between the anus and vagina

25
Q

What is the attachment site for the superficial and deep perineal muscles, the levator ani muscle as well as the external anal sphincter?

A

the perineal body

26
Q

What is the origin of the pudendal nerve?

A

S2-S4 ventral rami

27
Q

The perineal and pelvic muscles receive voluntary motor innervation from which nerve?

A

the Pudendal nerve (S2-S4)

28
Q

Which artery supplies the perineum?

A

the Internal pudendal artery

29
Q

From which artery does the Internal pudendal artery branch?

A

the anterior division of the Internal iliac artery

30
Q

During the female sexual response, which nerve dilates blood vessels in erectile tissue and stimulates vestibular gland secretions?

A

Pelvic splanchnic nerve (parasympathetic)

31
Q

Which plexus of nerves does the pelvic splanchnic nerve transmit signals through?

A

the inferior hypogastric plexus of nerves

32
Q

During male and female sexual responses, which nerve causes rythmic contraction of the pelvic and perineal muscles?

A

the Pudendal nerve

33
Q

In the female sexual response, what role does sympathetic tone play?

A

rhythmic contraction of the pelvic organs and dilation of the cervical canal

34
Q

Which spinal cord levels are responsible for sympathetic tone during sexual arousal?

A

T10-L2

35
Q

Without FSH, how far can a ovarian follicle develop?

A

primary follicle

36
Q

Which hormone is responsible for an increase in body temperature during the ovarian cycle?

A

progesterone

37
Q

What is Priapism?

A

a prolonged, often painful erection that lasts longer than 4 hours without sexual stimulation

38
Q

What are 3 potential causes of priapism?

A

Sickle-cell disease, venemous insect bites, certain medications

39
Q

In treatment of priapism, what type of adrenergic receptor will phenylephrine bind? What is the intended effect?

A

alpha-2 adrenergic receptor; vasoconstriction, and decreased blood flow

40
Q

What is the spermatic cord?

A

A cord-like structure that contains blood vessels, lymphatic vessels, nerves, and the ductus deferens

41
Q

the frenulum of the penis receives innervation from both the dorsal penile nerves as well as what other nerve?

A

the perineal nerve
