The Reproductive System
What are the principle structures of the male reproductive system and
what are they comprised of?
The testes are the principle structure of the male reproductive
system. The testes are comprised of thousands of fine, coiled tubule
in which the sperm are produced.
What other parts of the male reproductive system are they continuous
with?
The tubules in the testis are continuous with the epididymis, where
the sperm matures, and the vas deferens. The vas deferens transports
the sperm from the testis and joins the urethra just below the
bladder.
What part of the system is involved in secreting seminal fluids?
The seminal vesicles and the prostate gland secrete fluids during
ejaculation. These fluids are the sperm make up the semen that is
released via the penis.
What is the purpose of seminal fluid?
The seminal fluids improve the mobility of the sperm, neutralize the
acidity in the female reproductive tract and cause coagulation of the
semen after ejaculation.
What are the ovaries, what are they suspended by and what is their
function?
There are two ovaries which are suspended by ligaments in the upper
pelvic cavity either side of the uterus. Their function is to produce
the hormone oestrogen and progesterone and to produce ova.
What causes follicles to develop and what do they become?
Each immature ovum is encased in a sac and the whole structure is
called a follicle. The follicles develop, usually one at a time, in
response to the various sex hormones until they become primary
follicles.
Describe the fallopian tube and its purpose.
The fallopian tubes connect the ovaries to the uterus. Each fallopian
tube resembles a long, thin funnel that is wider at the ovary and
narrower at the uterus. At the ovary end, the fallopian tube has
finger like projections called fimbriae, these encourage the mature
sperm to enter the fallopian tube. If fertilisation occurs, it usually
takes place in the wider part of the fallopian tube.
The testes produce sperm and sex hormones, testosterone. Surrounding each testis is a coiled tube called the epididymis, which collects and stores sperm, very much similar to that of a human. Before ejaculation a seminal fluid is added by the seminal vesicles, to prevent the sperm from drying out.
In Ruth Gilbert’s At the Border’s of the Human, she discusses society’s interest in hermaphrodites in terms of “people’s desire to examine, scrutinize, and display objects which are alien, strange and other” (6). The anomalous and bizarre spectacle of the hermaphroditic body has drawn the focus of scientists since the early sixteenth century. Hermaphrodites have long evoked a “mixture of disgust and desire, and fear and fascination”(Gilbert 150) that has led to their position as objects of scientific scrutiny. As defined by Random House Webster’s College Dictionary, a hermaphrodite is “an individual in which reproductive organs of both sexes are present”. Besides hermaphrodites challenging society’s physical norms, they challenge and have recently changed its cultural norms as well.
The Female reproduction cycle includes seven key parts; FSH, LH, estrogen progesterone, ovulation, menstruation and pregnancy. When fertilization occurs, the egg will begin to divide through mitosis. After several divisions a cluster of cells surrounding the embryo, called a blastocyst implantation .Where they attach to the uterine wall by the secretion of enzymes. Within a few days of this process the uterus will continually divide , the embryo; Releasing hormones to keep the corpus luteum functioning for a few weeks to allow nourishment and protection to reach and line the uterus. Then membrane like chorionic villi are formed to help with protection. These form an essential organ called the placenta; the connection between mother and embryo. This serves as the embryo’s main source of nourishment.
It is in fact the case that researchers and scientists use gendered language when discussing eggs and sperm. Emily Martin has researched this phenomenon and discussed the implications that can occur. In her paper, “The Egg and the Sperm: How Science Has Constructed a Romance Based on Stereotypical Male-Female Roles”, Martin shed light on the way eggs and sperm are discussed in the science field. She described sperm being discussed as dominant, forceful, and active while eggs were labeled passive, submissive and a damsel in distress. New research has discovered that contrary to popular belief, sperm’s thrust in the egg is actually weak. Rather than forcefully penetrating the egg, the sperm moves
Gender stereotypes have existed since the beginning of modern man. We've all heard them before; male dominance and female weakness, a controlled male and a flustered female, aggression and passion, and many others that all basically boil down to the same thing. Emily Martin, in her essay entitled The Egg and the Sperm, takes this problem of gender stereotype to a new and much more serious level. As an anthropologist, Martin is concerned with the socio-cultural impacts on many different aspects of everyday life, including biology. In doing her research for this article, Martin was trying to uncover suspicions she had about socio-cultural gender stereotypes, and the affects they had on the diction used to describe egg and sperm interactions in numerous biology books and research reports.
The main difference between male and female primates is that female primates are the ones who conceive an offspring. If primate males were the ones to conceive, then the roles would be completely different. There are two different reproduction strategies the male and female follow in the primate world. The male strategy would be to always be ready and wanting to mate, so he can maximize reproductive success. The female reproductive strategy would be to make males compete for her and also to select a quality male (Male with territory and/or ability to protect her and her offspring). Another female reproductive strategy that will benefit her is, sneaky copulation because it creates a confused paternity so, if the transient male takes over the group the offspring will not be killed. The male parental investment is fairly low; mostly all the male does is just give the sperm to the female and take off onto seeking another mate. As for the female parental investment, it’s extremely high; because she must grow the offspring in her body, give birth, nurse and raise the young. The factors of limiting male’s reproductive success would be female access and competition with another male. As for the factors of limiting female’s reproductive success would be food resources, and a predator free space. The male strategies maximize reproductive success because, with males spending less time on parental investment they can seek more mating opportunities; for a chance the female will take care of the offspring so that his genes can be passed on. Another way males maximize their reproductive success would be to eliminate all unfertile females from their mating because there is no way that the male genes could be passed on. Females use their strategy ...
From here, the reproductive system leads into the female, with the semen being inserted. It fertilizes the egg and then a baby is born.
C. malina has grayish-black mycelium. However, no conidia have been observed in this fungus. Researchers have not observed either asexually reproductive or sexually reproductive structures both in the field and in laboratory conditions. The attempt to induce production of reproductive structures by Tomaso-Peterson et al.in 2016 was not successful (Tomaso-Peterson et al. 2016). Other species in the Curvularia genus do produce reproductive structures. Production of conidia and spores has been observed in Curvularia inaquaelis (Kim et al. 2000).
The Reprodructive system or genital system is a system of sex organs within an organism which work together for the purpose of sexual reproductive. A human has 46 chromosomes in each cell except sex cells. A person recieve 23 chromosomes from the mother and 23 chromosomes from the father . The mother has X chromosome and the father has Y chromosome . XY chromosomes are also found in other mammals , some insects and some plants . Now let’s talk about the male reproductive system. The male reproductive system consists two major parts which are testes and penis . The spermatozoa (sperm) includes four main parts of the male body which are the penis , uretha , vas defences , and cowper’s gland . Testes is where the sperm
The prevalence of diagnosed endocrinological disorders has increased during the 20th century and into the 21st century. These disorders interfere in the day to day lives of those who have them. A common disorder of the endocrine system is diabetes, type 1 and type 2. While there have been many treatment methods used of the years the use of biotechnology like recombinant DNA technology has revolutionized and standardized the treatments.
The Female Reproductive System parts are gametes, which is a mature haploid male or female germ cell that is able to unite with another of the opposite sex in several reproductions to form a zygote. Egg is a person possessing a specified quantity. Ovum is a mature female reproductive cell especially of a human or other animal that van divide to give rise to an embryo usually only after fertilization by a male cell. Vaginal is a muscular tube leading from the external genitals to the cervix of the uterus in women and most female mammals. Labia is the inner and outer folds of the vulva, at either side of the vagina. Clitoris is a small sensitive and erectile part of the female genitals at the anterior end of the vulva. Urethra is a duct by which urine is convey out of the body from the bladder and which in male vertebrates also conveys semen. Hymen is a membrane that partially closes the opening of the vagina and whose presence is traditionally taken to be a mark of virginity. Uterus is the organ in the lower body of a women or female mammal where offspring are conceived and in which they gestate before birth; the womb. Cervix is a narrow like passage forming the lower end of the uterus. Fallopian tube is either of a pert of tubes along which eggs travel from the ovaries to the uterus. Ovary is a female reproductive organ in which ova or eggs are produces, present in humans and other vertebrates as a pair. Estrogen is a group of steroid hormones that promote the development and maintained of female characteristics of the body. Progesterone is a steroid hormone released by the corpus lutetium that stimulates the uterus to prepare for pregnancy. The Male Reproductive System parts are testes, which is an organ that produces spermatozo...
The male reproductive system is a set of organs that works together to produce sperm which will later in life fertilize females eggs. The testes are the most important part of the system because it produces sperm cells. It is similar and looks similar to ovaries of a female’s reproductive system because it also holds what they need to reproduce. Its job is to produce the sperm cells needed to reproduce. Due to hormonal imbalances the production of sperm cells may not even be possible in some males. Testosterone is the male the hormone that gives men there manly characteristics. It is made up of hydrogen, carbon, and oxygen with a white color. In the male body it helps develop sex organs, a deeper voice, and facial hair (Khalid, 2013). Cancer or a genetic disorder in males is the most common thing that cause the reductions of testosterone production in the body. Behind the testes is the epididymis which lets sperm go through the vas deferens from the testes (Dictionary, 2014). It looks like leach the way it is position right on the testes but it is thinner. When sperm is produces the ...
The reproductive system is the part of the human body that is necessary to continue the human existent. Reproduction in humans normally would begin by a male and female having sexual intercourse with each other.
The human body is very complex. It is like a job. You have to do a million things in one day to make it through the day. The body uses nine systems to do all of those jobs. They all have separate functions, but some work together. Each system is also made up of organs. There are many ways to care and protect the systems from the many different problems they can have. There are also many interesting facts about each system.
The reproductive systems are based off of the goal to create offspring. Both the male and the female reproductive systems, although fueled by a similar goal, have different components and structures. Both systems are very complex in their own way, making it important for one to understand how each of the systems and their various processes work. Knowing the processes and components of the male and female reproductive systems will aid all people in their life, sometime or another. It’s important to understand how our individual bodies work and how life is produced.
