Q

What foramen in the pelvis does the piriformis pass through?

Q

In males the muscle of the bladders neck is continuous with what structure

27
Q

The mesovarium accomplishes what job?

A

The mesovarium suspends the ovary.

28
Q

The mesosalpinx accomplishes what job?

A

Suspends the uterine tube

29
Q

The Mesometrium accomplishes what job?

A

The mesometrium suspends most of the uterus.

30

32
Q

What is the innervation of the vagina?

A

Th upper 3/4 is autonomically controlled where as the lower 1/4 is somatically controlled and innervated by the deep perineal branch of the pudendal.

33
Q

When the ductus deferens joins the seminal vesicle what does it become?

A

The ejaculatory duct which converges upon the seminal colliculus of the prostatic urethra.

34

What components make up semen?

A

Semen is a mixture of secretions by the testes, seminal vesicles, prostate, and bulbourethral glands.

35
Q
