1.
Which of these do the Ovaries produce?
Correct Answer(s)
A. Oestrogen
B. Progresterone
D. Oocytes
E. Female Sex Hormones
Explanation
The ovaries produce oestrogen, progesterone, oocytes, and female sex hormones. Oestrogen and progesterone are two important hormones involved in regulating the menstrual cycle and maintaining pregnancy. Oocytes are immature eggs that are produced by the ovaries and eventually develop into mature eggs for fertilization. Female sex hormones, including oestrogen and progesterone, play a crucial role in the development and functioning of female reproductive organs and secondary sexual characteristics.
2.
Where do Oocytes mature?
Correct Answer
A. In follicles in the ovaries.
Explanation
Oocytes, or immature eggs, mature in follicles within the ovaries. The ovaries contain numerous follicles, each containing an oocyte. During each menstrual cycle, one follicle will mature and release a mature egg through the process of ovulation. The oocyte undergoes a series of complex changes within the follicle, including growth and development, until it is ready to be released and potentially fertilized. The fallopian tubes and the ampulla are not sites of oocyte maturation, but rather play a role in the transport and fertilization of the mature egg.
3.
Fallopian Tubes are also called the Oviducts and they receive and transport mature oocytes from the ovary.
Correct Answer
A. True
Explanation
The statement is true because the fallopian tubes, also known as oviducts, play a crucial role in the reproductive system of females. They receive the mature eggs (oocytes) from the ovary and provide a pathway for them to travel towards the uterus. This is where fertilization typically occurs if sperm is present. Therefore, it is correct to say that the fallopian tubes receive and transport mature oocytes from the ovary.
4.
What role does the Oviduct play in the transportation of Spermatazoa?
Correct Answer
A. Transports them from the Uterus to the Ampulla.
Explanation
The oviduct, also known as the fallopian tube, plays a crucial role in the transportation of spermatozoa. It serves as a pathway for the sperm to travel from the uterus to the ampulla, which is the widest part of the fallopian tube. This transportation is necessary for fertilization to occur, as the sperm needs to reach the egg in the ampulla for fertilization to take place. Therefore, the correct answer is that the oviduct transports spermatozoa from the uterus to the ampulla.
5.
What features of the Ovidcut facilitate the transport of spermatozoa from the Uterus to the Ampulla?
Correct Answer(s)
A. Smooth muscle contraction
B. Ciliated Epithelia
Explanation
Smooth muscle contraction and ciliated epithelia are the features of the Oviduct that facilitate the transport of spermatozoa from the Uterus to the Ampulla. Smooth muscle contraction helps in the movement of spermatozoa through peristaltic contractions, while ciliated epithelia create a wave-like motion that propels the spermatozoa forward. These features work together to ensure the efficient transport of spermatozoa along the oviduct towards the site of fertilization.
6.
The Oviduct provides a nutrient-rich environment for both the spermatozoa and the zygote - facilitates fertilization. It also transports the embryo to the uterus where it develops.
Correct Answer
A. True
Explanation
The Oviduct, also known as the fallopian tube, plays a crucial role in the reproductive process. It provides a nutrient-rich environment for both the spermatozoa and the zygote, which enhances the chances of successful fertilization. Additionally, the oviduct transports the developing embryo to the uterus where it can implant and further develop. Therefore, the statement that the oviduct provides a nutrient-rich environment for both the spermatozoa and the zygote, and facilitates fertilization, as well as transports the embryo to the uterus, is true.
7.
What if these are features of the inner lining of the oviduct?
Correct Answer(s)
A. Concentric layers of smooth muscle
B. Ciliated Epithelium
C. Mucus Producing cells
Explanation
The features listed are all characteristics of the inner lining of the oviduct. The concentric layers of smooth muscle allow for the contraction and movement of the oviduct, aiding in the transport of eggs. The ciliated epithelium helps to move the eggs along the oviduct through coordinated beating motions. Mucus-producing cells secrete mucus, which provides lubrication and protection for the eggs. Connective tissue provides support and structure to the oviduct.
8.
The uterus is situated between the____________ , and is where the embryo develops.
Correct Answer(s)
rectum and the bladder
Explanation
The correct answer is rectum and the bladder. The uterus is located between these two organs and serves as the site for embryo development.
9.
Which of these is true about the uterus?
Correct Answer(s)
A. Held in place by uterine ligaments attached to the pelvic cavity.
B. Transports spermatazoa to the oviduct.
D. Supplies fetus with nutrients and removes waste products.
E. Protects and transports fetus at birth.
Explanation
Consists of Endometrium, Myometrium and PeriMETRIUM
10.
It is a mucosal layer than contains endocrine glands that produce nutritive secretions. Regulated by ovarian hormones and varies in thickness during menstruation.
Correct Answer
A. Endometrium
Explanation
The endometrium is a mucosal layer that lines the uterus and contains endocrine glands. These glands produce secretions that nourish a developing embryo if fertilization occurs. The thickness of the endometrium varies during the menstrual cycle and is regulated by ovarian hormones. This layer is shed and regenerated during menstruation. The other options, myometrium and perimetrium, refer to different layers of the uterus but do not produce nutritive secretions like the endometrium does.
11.
Is a muscular layer that is regulated by ovarian hormones and oxytocin which causes increased force and rate of uterine contractions
Correct Answer
B. Myometrium
Explanation
The myometrium is the correct answer because it is a muscular layer of the uterus that is regulated by ovarian hormones and oxytocin. Ovarian hormones, such as estrogen and progesterone, play a role in the growth and development of the myometrium. Oxytocin, a hormone released during labor, stimulates the myometrium to contract, causing increased force and rate of uterine contractions. The myometrium's muscular contractions are essential for various reproductive functions, including menstruation, childbirth, and the expulsion of the placenta after delivery.
12.
Is a serosal outer layer
Correct Answer
C. Perimetrium
Explanation
The perimetrium is the outer layer of the uterus, consisting of a serosal covering. It acts as a protective layer and helps to keep the uterus in place within the pelvic cavity. The endometrium is the innermost layer of the uterus, which undergoes changes during the menstrual cycle to prepare for implantation of a fertilized egg. The myometrium is the middle layer of the uterus, composed of smooth muscle tissue that contracts during labor and menstruation. Therefore, the correct answer is perimetrium.
13.
Which of these does the cervix contain?
Correct Answer(s)
A. Collagen
B. Elastin fibres
C. Mucus glands
Explanation
The cervix contains collagen, elastin fibers, and mucus glands. Collagen provides structural support and helps maintain the shape of the cervix. Elastin fibers allow the cervix to stretch and contract during childbirth. Mucus glands produce mucus, which helps to keep the cervix moist and lubricated. These components work together to ensure the proper functioning of the cervix.
14.
What is the function of the mucus produced in the cervix?
Correct Answer(s)
A. Lubricates the vagina during sex.
B. Transports bacteria and foreign particles away from the reproductive tract.
Explanation
The mucus produced in the cervix serves multiple functions. One of its functions is to lubricate the vagina during sexual intercourse, which helps to reduce friction and enhance comfort. Additionally, the mucus acts as a protective barrier by transporting bacteria and foreign particles away from the reproductive tract, helping to prevent infections and maintain overall reproductive health.
15.
What type of epithelium is found in the vagina, which may be keratinised during oestrus?
Correct Answer
A. Stratified squamous
Explanation
The correct answer is stratified squamous. The vagina is lined with a stratified squamous epithelium, which means that it is made up of multiple layers of flattened cells. During oestrus, the cells in the vagina may become keratinized, meaning that they develop a tough, protective layer of keratin. This helps to protect the vaginal tissue during the reproductive process.
16.
What structure are found external to the vagina?
Correct Answer(s)
B. Vestibulum
C. Clitoris
D. Labia
Explanation
The structures that are found external to the vagina are the vestibulum, clitoris, and labia. The vestibulum is the area surrounding the vaginal opening and contains the openings of the urethra and the Bartholin's glands. The clitoris is a highly sensitive organ located at the top of the vulva, responsible for sexual pleasure. The labia are the folds of skin that protect the vaginal and urethral openings. The g-spot, although mentioned in the options, is not external to the vagina but rather an internal erogenous zone.
17.
Where does the egg develop in the avian repro system?
Correct Answer
A. Shell gland
Explanation
The shell gland, also known as the uterus, is where the egg develops in the avian reproductive system. This gland is responsible for the secretion of the shell material that surrounds the developing egg, providing protection and support. The egg moves through the oviduct, with the shell gland being the final stage before the egg is laid.
