the human reproductive system produces, nourishes, and transports functional male and female reproductive cells called

gametes

fertilisation, also known as conception, is where a male gamete and a female gamete…

unite

a ? is the term used for the single cell created by the fusion of a male gamete with a female gamete

zygote

the gradual transformation of a single cell into a functional adult is the process of ? which is directed by hormones of the reproductive system

development

the reproductive system includes each of the following components excepr

pineal structures

in both male and females, the reproductive system ducts are connected to chambers and passageways, constituting the ? that open to the exterior of the body

reproductive tract

in adult males, the testes secrete sex hormones called

androgens

during emission, mature spermatozoa travel along a lengthy duct system where they are mixed with secretions of accessory glands forming

semen

in adult human females, the ovaries typically release only one immature gamete called an oocyte per

month

the immature oocyte travels along short uterine tubes, ending in a uterus, and a short passageway called the ? connects the iterus with the exterior

vagina

during sexual intercourse, ejaculation of the male introduces semen into the vagina and the ? ascend the female reproductive tract

spermatozoa

after initialising of fertilisation, the oocyte matured into an ovum, and the uterus is enclosed to support the next step of development into a

embryo

proceeding from a make testis, spermatozoa travel within each of the following except

vas efferens

accessory organs of the male reproductive system, which secrete various fluids into the ejaculatory ducts and urethra, include each of the following excepr

bladder

the male external genitalia consist of the

scrotum and penis

in the testes, ? are responsible for the produyof androgens, the dominant sex hormones in males

interstitial (leydig) cells

spermatozoa are generated by the process of spermatogenesis, which involved three integrated processes in the following order

mitosis, meiosis, spermiogenesis

spermatogonia (stem cells) divide by ? to produce daughter cells, some of which differentiate into primary spermatocytes

mitosis

meiosis is a special form of cell division involved in gamete production, where gametes contain

23 chromosomes (half the normal set)

in the semniferous tubules, meiotic divisions that begin witj primary spermatocytes produce

spermatids

spermatozoa are

among the most highly specialised cells in the body

the principle organs of the female reproductive system include each of the following excepr

urethra

which of the following functions do the ovaries not perform

secretion of follicle stimulating hormone (FSH)

the interior tissues, or ? of the ovary can be divided into superficial cortex and deeper medulla

stroma

oogenesis begins before a woman’s birth, accelerates at puberty, and ends at menopause, oogensis occurs monthly as part of the

ovarian cycle

the female stem cells, oogonia, complete their ? divisions before birth

Mitotic

between the ? if the female fetal development, the daughter cells prepare to undergo meiosis

third and seventh month

after undergoing first steps of meiosis the process comes to a halt and tbf primary oocytes remain in a state of suspended development until the individual reaches puberty when rising levels of ? trigger start of ovulation

FSH

not all primary oocyte produced during development will survive until puberty and while the ovaries have around 2 million primordial follicles at birth degeneration by a process called ? results in a drop in this number to around 400,000 by puberty

atresia

the follicular phase is known as

preovulatory phase

which step occurs after ovulation

formation of the corpus luteum

the menstrual cycle averages 28 days and can be divided into three stages on which order

menses, proliferative phase, secretory phase

during menses, there is a degeneration of the functional zone of the endometrium, which is sloughed by a process called

menstruation

In the days after mensus, there is a functions reorganisation for restoration of the functional zone of the endometrium, stimulated and sustained by

estrogens

the secretory phase of the uterine cycle lasts around

14 days

the activity of th femal reproductive tract is under hormonal control, involving an inter-play between secretions of both the ? and the gonads to coordinate the ovarian and uterine cycles

pituitary glands

which of the following is not an estrogens circulating in the bloodstream

estragone

each of the estrogens have similar effects on target tissues and these include each of the following except

initiating shedding of the endometrium

mammary glands are specialised organs that are controlled mainly by hormones of the reproductive system and by the ?, a temporary structure that provides nutrient for embryo

placenta

? usually defined as time of ovulation and menstruation ceases

menopause

how many spermatozoa are produced from each spermatogonium

what is the main role of progesterone during the luteal phase of the ovarian cycle

prepare the endometrium for implantation of the embryo

which is the common precursor for all sex hormones

cholesterol

sertoil cells perform all of the following functions except

secretion of androgens

at which stage of life are testosterone levels highest

puberty

what is the main stimulus for ovulation

release of LH from pituitary gland
