Reproductive System
Sperm become motile in the
epididymis
The function of the pampiniform plexus of veins is to
help cool blood
This layer of the uterus contracts during parturition to expel the baby.
myometrium
Tubules that connect testicular lobules with the efferent ductules of the epididymis
rete testis
In cows, the nipples (teats) are in the groin region, not in the midthorax as in humans. What is the most logical reason for this difference between cows and people
Cows' mammary glands arise from a different part of the milk line.
The usual site of embryo implantation is the
uterus.
Fingerlike placental structures where oxygen and nutrients from the maternal blood supply diffuse into the embryonic blood
chorionic villi
A woman has developed a cancerous lump in each breast, and the skin of the breasts is dimpled. What structure(s) is (are) causing the dimpling
suspensory ligaments of the breast
This multinucleate embryonic structure invades the uterus, digesting cells and maternal blood vessels to make way for development of the placenta.
syncytiotrophoblast
At what point during fetal development is the decidua basalis/chorionic villi collectively referred to as the placenta?
the start of fourth month
Which of the following is the primary sex organ in the male?
the testis
Type of cell in the testes that produces testosterone.
interstitial
A woman's sex cells (germ cells) originate embryologically
from yolk sac endoderm.
The opening of the oviduct is surrounded by these structures.
fimbriae
Fertilization of the ovum normally occurs in this region of the oviduct.
ampulla
The fluid-filled cavity in a mature ovarian follicle is known as
antrum.
nvoluntary contraction of this smooth muscle layer wrinkles and thickens the walls of the scrotum to prevent heat loss
dartos muscle
Tubular organ that is transected during a vasectomy.
ductus deferens
The female homologue of the male scrotum is the
labia majora
The correct sequence of sperm-transporting tubules that transport spermatozoa to the epididymis is the
seminiferous tubule to straight tubule to rete testis to efferent ductule
A factor that propels an oocyte through the uterine tube is
smooth muscle contraction (peristalsis).
