SpermIOgenesis (final stage of development)
The secretion of the seminal vesicles makes up about __________% of the volume of semen, and the secretion contains __________
60 / fructose, prostaglandins, substances that enhance sperm motility
Graafian Follicle
contains a secondary oocyte surrounded by zona pellucida and corona radiata
The ovarian cortex consists of
follicles and connective tissue
Involuntary contraction of this smooth muscle layer wrinkles and thickens the walls of the scrotum to prevent heat loss.
Dartos muscle
In which part of breast tissue does breast cancer typically arise?
Duct System
Tubular organ that is transected during a vasectomy.
Ductus Deferens (vas deferens)
Which hormone stimulates the development of the endometrium during the proliferative phase of the uterine?
Estrogens secreted by the follicle stimulate development of the functional layer of the endometrium.
The ejaculatory ducts are formed by the union of the ductus deferens and urethra.
FALSE
The spermatic cord is another name for the ductus deferens.
FALSE
Seminiferous tubules are the site of sperm storage.
FALSE, the answer is Epididymis
Which hormone stimulates the growth and development of the ovarian follicle?
FSH
The opening of the oviduct is surrounded by these structures.
Fimbriae
By undergoing meiosis, each primary spermatocyte ultimately gives rise to how many sperm cells?
Four

Helps regulate temperature
Oogenesis takes years to complete.
from birth to puberty
Name of the organ that directs sperm toward the seminal vesicles during ejaculation.
Vas Deferens
In an adult woman who has never been pregnant, the breasts have poorly developed or no

The largest macroscopic region of the uterus is its
Body
The__________ is homologous to the penis, having both a glans and a body.
Clitoris
The female homologue of the male scrotum is the
Labia Majora
The seminal vesicles
are glands that secrete most of the volume of the semen.
Thecal Folliculi
connective tissue layer that condenses around a primary follicle; outer layer cells resemble smooth muscle cells and inner layer secretes hormones
Secondary Follicle
first follicle to have a well-defined antrum; comprised of stratified epithelium
A factor that propels an oocyte through the uterine tube is
smooth muscle contraction (peristalsis)

surrounds the tip of the cervix.
Which of the following is the primary sex organ in the male?
testis
A difference between a primary follicle and a primordial follicle is that
the primordial follicle has only a single layer of flat follicular cells, whereas the primary follicle is comprised of cuboidal follicle cells.

where ectopic pregnancies commonly occur.
In the fallopian tubes
Type of cell in the testes that produces testosterone.

What cells are located in the seminiferous tubules?
The stem cells, spermatogonia, are located in the basal compartment. Some cells move toward the adluminal compartment to begin meiosis I and become primary spermatocytes.
