Boutan however described a "glande annexe" in the internal wall of the genital duct in F.
A gland of unknown function associated with the genital duct like that described by these authors is also found in F.
Those that play direct roles include the gonads, genital ducts, and external genitalia.
In the first step of sexual differentiation, the differentiated gonad directs development of the genital ducts and external genitalia.
In addition, two sets of genital ducts (Wolffian and Mullerian) are readily apparent and extend from the mesonephros to the urogenital sinus.
The genital ducts of the female include the vagina, uterus, and oviducts.
Microscopically, the cervix resembles the other portions of the genital ducts, but with some notable exceptions (Figure 5-29).
Gonadal hormones act on the genital ducts, external genitalia, mammary glands, brain, anterior pituitary gland, and other tissues not directly involved with reproduction.
As noted earlier, the activity of the reproductive system proper (i.e., the gonads, genital ducts, and external genitalia) is regulated by the pituitary gland, which is regulated by the brain.
In June the follicles contained a quantity of sperm, which in many males was flooding into the genital ducts
The ducts of the genitals (epididymis and ductus deferens in males, and vagina, uterus, and oviducts in females).
