Learning aim C: Understand the role of hormones in the regulation and control
of the reproductive system
Title: Hormonal control of reproduction
Fallopian tubes - The female structures that transport the ova from the ovary
to the uterus each month are known as uterine tubes, oviducts, or fallopian
tubes. The uterine tubes transfer the fertilised egg to the uterus for
implantation in the presence of sperm for fertilisation.
Ovary - The ovaries are little oval-shaped glands on either side of the uterus
that produce eggs. The ovaries produce eggs and hormones. They also produce
oestrogen and progesterone which are important female reproductive
hormones. The ovaries release eggs during the menstruation cycle (ovulation).
Uterus - After leaving the ovary, the egg can be fertilised and implanted in the
uterus. The uterus' primary purpose is to nourish the developing foetus prior
to birth. The uterus also offers protection to avoid damage to the fetus.
,Fimbriae - The uterine tube fimbriae, also known as fimbriae tubae, are short,
finger like extensions at the end of the fallopian tubes that transport eggs from
the ovaries to the uterus. The ovary is attached to the fimbriae.
Endometrium - The endometrium is the uterus's innermost lining layer, which
is mostly made up of mucosal tissue. The tissue that makes up the uterus, or
womb, the pear-shaped organ that holds a developing baby, acts as
"wallpaper."
Cervix - Cervical mucus is produced by the cervix and changes in consistency
throughout the menstrual cycle to prevent or promote conception. The cervix
dilates dramatically during childbirth to allow the baby to pass through. During
menstruation, the cervix opens a small amount to allow menstrual flow to pass
through.
Vagina - The vagina is a muscular tube in front of the rectum and behind the
bladder that is lined with nerves and mucus membranes. Furthermore, the
uterus and cervix are joined by the top portion of the vagina. The bottom
section of the vagina, on the other hand, opens to the outside of the body. As a
result, the vagina can perform three essential roles. provide a gateway for
childbirth, accept penis during intercourse, and provide a pathway for blood
from the uterus during monthly menstruation. The vagina can enlarge,
broaden, and swell up with blood as it prepares to take the penis or as it
prepares for birthing, even though it is only approximately 9cm long.
Labia - The labia minora are two thick cutaneous folds that comprise a
component of a woman's vulva. Pigmented skin, oil-secreting glands, and
coarse hair termed pubes cover the outer sides of the labia folds following
puberty. The inner sides of the labia folds, however, are smoother, with less
hair and some sweat traces. The labia minora's primary role is to protect and
surround the external genital organs.
, Epididymis - The epididymis is a long, coiled tube that delivers sperm from the
testes and stores it. On the posterior (rear) margin of each testis, it appears as
a curved structure. It is divided into three parts. The head, body, and tail. The
head's function is to secrete sperm until they are mature enough to undergo
maturation. The epididymis' body appears like a lengthy, twisted tube that
permits sperm to mature properly. The epididymis' tail attaches to the vas
deferens, which serves as a doorway for sperm cells to travel to the ejaculatory
duct.
Seminal vesicle - Seminal vesicle, one of two elongated saclike glands in male
mammals that secrete their fluid contents into the ejaculatory ducts. The
seminal fluid is mostly made up of the secretion of the seminal vesicles. The
seminal vesicles' primary role is to produce and store a fluid in the proper
environment for each sperm cell's proper functioning and survival.
Cowper's gland - Cowper's glands are pea-sized glands found in the male
reproductive system below the prostate gland. Prior to ejaculation, they create
a thick, clear mucus that drains into the spongy urethra. Furthermore, the
Cowper's gland is in charge of producing a prostate antigen.
