seminiferous tubules
From the lumen of the ________, the immotile sperm are surrounded by testicular fluid and moved to the epididymis (plural= epididymides), a coiled tube attached to the testis where newly formed sperm continue to mature.
menarche
The first menses after puberty, called ________, can occur either before or after the first ovulation.
sustentacular cells
In males, secretions from ________ trigger a degradation of the female duct, called the Müllerian duct.
spermatogonia
The process that begins with ________ and concludes with the production of sperm is called spermatogenesis.
external female reproductive structures
The ________ are referred to collectively as the vulva.
female gonads
The ovaries are the ________.
Puberty
is the stage of development at which individuals become sexually mature.
Wolffian duct
At the same time, testosterone secretion stimulates growth of the male tract, the
Müllerian duct
In males, secretions from sustentacular cells trigger a degradation of the female duct, called the
menarche
The first menses after puberty, called
cervix
The _ is the narrow inferior portion of the uterus that projects into the vagina.
body of uterus
The middle section of the uterus is called the ___ (or corpus).
fundus
The portion of the uterus superior to the opening of the uterine tubes is called the
ampulla
The middle region of the tube, called the
isthmus
is the narrow medial end of each uterine tube that is connected to the uterus.
uterine tubes
(also called fallopian tubes or oviducts) serve as the conduit of the oocyte from the ovary to the uterus
tertiary follicles (or antral follicles)
Follicles in which the antrum has become large and fully formed are considered
antrum
A thick fluid, called follicular fluid, that has formed between the granulosa cells also begins to collect into one large pool, or
primary follicles
After puberty, a few primordial follicles will respond to a recruitment signal each day, and will join a pool of immature growing follicles called
granulosa cells
Primordial follicles have only a single flat layer of support cells, called
primordial follicles
are present in newborn females and are the prevailing follicle type in the adult ovary
oogonia
The process begins with the ovarian stem cells, or
oogenesis
Gametogenesis in females is called
ovarian cycle
is a set of predictable changes in a female’s oocytes and ovarian follicles.
follicle
This grouping of an oocyte and its supporting cells is called a
corpus cavernosum
Each of the two larger lateral chambers is called a __ (plural = corpora cavernosa).
broad ligament
The ovaries are located within the pelvic cavity, and are supported by the mesovarium, an extension of the peritoneum that connects the ovaries to the
hymen
is a thin membrane that sometimes partially covers the entrance to the vagina.
labia majora
(labia = “lips”; majora = “larger”) are folds of hair-covered skin that begin just posterior to the mons pubis.
mons pubis
is a pad of fat that is located at the anterior, over the pubic bone. After puberty, it becomes covered in pubic hair.
Leydig cells
Testosterone, an androgen, is a steroid hormone produced by
prepuce (or foreskin)
The skin from the shaft extends down over the glans and forms a collar called the
glans penis
, has a high concentration of nerve endings, resulting in very sensitive skin that influences the likelihood of ejaculation.
corpus spongiosum
which can be felt as a raised ridge on the erect penis, is a smaller chamber that surrounds the spongy, or penile, urethra.
spermatic cord
The ductus deferens is a thick, muscular tube that is bundled together inside the scrotum with connective tissue, blood vessels, and nerves into a structure called the
ductus deferens
During ejaculation, sperm exit the tail of the epididymis and are pushed by smooth muscle contraction to the
spermiogenesis
transforms these early spermatids, reducing the cytoplasm, and beginning the formation of the parts of a true sperm.
spermatogenesis
The process that begins with spermatogonia and concludes with the production of sperm is called
spermatogonia
(singular = spermatogonium), line the basement membrane inside the tubule.
Sertoli cells
Surrounding all stages of the developing sperm cells are elongate, branching
gamete
is a specialized sex cell carrying 23 chromosomes one half the number in body cells.
sperm
At fertilization, the chromosomes in one male gamete, called a
scrotum
The testes are located in a skin-covered, highly pigmented, muscular sack called the
thick fluid
A(n) ________, called follicular fluid, that has formed between the granulosa cells also begins to collect into one large pool, or antrum.
testes
(singular = testis) are the male gonads that is, the male reproductive organs.
pregnancy
If no ________ occurs, the lining of the uterus is shed, resulting in a menstrual period.
