BIO108 Reproductive
| Question | Answer |
|---|---|
| Describe the main purpose of the reproductive system | to accomplish reproduction which is the creation of a new individual. |
| Name the functional reproductive cells of male | spermatozoa |
| Name the functional reproductive cells of female | oocyte |
| What are the organs that produce reproductive cells called | testes and ovaries |
| Explain what hormone is produced by the testes | testosterone |
| Explain what hormone is produced by the ovaries | estrogen and progesterone |
| gamete | Reproductive cells |
| zygote | Fertilized egg cell |
| seminiferous tubules | Located in the testicular lobule and highly convoluted. As sperm develop, they are released into the tubules. |
| epididymus | The embryonic Müllerian ducts degenerate and the Wolffian ducts become the epididymis. |
| bulbourethral glands | Add an alkaline secretion to the semen |
| ovaries | Primary sex organs of the female |
| fallopian tubes | Curves over the top edge of each ovary and opens into the abdominal cavity. They transport the ova from the ovary to the uterus. |
| uterus | The uterus greatly expands during pregnancy to accommodate the growing embryo and a large among of fluid. |
| endometrium | Inner mucous later of the uterine wall. |
| myometrium | Extremely thick, smooth, muscular middle layer, of the uterine wall. |
| vestibule | Opening or region between the labia minora |
| aureole | Ring of tissue that surrounds the nipple of the breast. |
| menarche | When the reproduction years start. This is the initial menstrual discharge of blood. |
| Describe the correct sequence of sperm travelling through the reproductive tract | After sperm leaves the testes, it passes through the epididymis, ductus deferens, ejaculatory duct, and urethra. |
| Semen exits the penis through what structure? | Urethra |
| What does diploid mean? | Diploid is two complete sets of chromosomes, one from each parent. |
| What does Haploid mean? | Haploid is a single set of unpaired chromosomes. |
| What is the function of the prostate? | To prevent the passage of urine through the urethra and aids in expulsion of semen during ejaculation. |
| Name the male organ of copulation | Penis |
| Explain the role of FSH and LH in Males? | FSH stimulates the production of sperm. |
| Explain the role of FSH and LH in Females? | FSH promotes the secretion of estrogen to the ovary. |
| What is the mass of erectile tissue located at the anterior region of the labia minora? What is it analogous to? | Clitoris. Penis |
| Name the portion of the uterus that extends into the vagina: | Cervix |
| What are the labia majora? Labia minora? | Folds of skin that surround your vagina opening. Labia majora is the outer and labia minora is the inner. |
| In what glands does milk production occur? | Mammary glands. |
| How many functional gametes are produced at the end of spermatogenesis? Oogenesis? | 4 1 |
| What happens during menses? | Blood and dead cells pass through and out the vagina. |
| What surrounds the proximal urethra in the male? | Prostate gland |
| The ??? provides a passageway for delivery of offspring as well as for uterine secretions. | vagina |
| What makes a fluid that lubricates the penis for sexual intercourse? _. | Bulbourethral glands |
| Inflammation of the vaginal wall is called | vaginitis |
| Which structure secretes a fluid rich in sugars and prostaglandins? | Seminal vesicles |
| Inflammation of the epididymis is called | epididymitis |
| Severe painful cramps during menstruation is called | dysmenorrhea |
| The ??? produces an alkaline fluid and secretes this fluid into the urethra just before ejaculation to protect the sperm when they enter the acidic environment of the female vagina. | prostate gland |
| Absence of a menstrual cycle is called | amenorrhea |
| Another name for the prepuce is | foreskin |
| The primordial follicle is composed of an ovum and the surrounding | granulosa cells |
| After ovulation, the follicular cells become | granulosa cells |
| What covers the inner wall of the fallopian tubes. | Peritoneum |
| The three phases of the uterine cycle include: | menses proliferative phase secretory |
| The process of gamete formation is called | meiosis |
| Another name for the ductus deferens is | vas deferens |
| The top of the sperm head is covered by an | acrosome |
| Which organ structures secretes estrogen and progesterone? | ovaries |
| Ovulation occurs ??? | around day 14 of your menstrual cycle. |
| The body of the sperm contains ??? These are necessary to generate energy used for? | mitochondria reaching the egg |
| During the ovarian cycle, the increase in leutanizing hormone occurs at the same time that levels of estrogen decrease. | True |
| The acrosomal cap contains enzyme necessary for the sperm to enter the ovum during fertilization. | True |
| The primary sex organ(s) for the male reproductive system is/are the | testes |
| ??? is the sugar that provides energy to immature sperm. | Fructose |
| Explain why prostaglandins are present in semen. | To influence sperm density and sperm function. |
| Which component of the testes is affected by LH? | Testosterone production |
| The erectile tissue(s) that is/are found in both the clitoris and the penis | corpora cavernosa |
| Name the process that results in the final number of chromosomes in the egg cell: | meiosis |
| Which part of the sperm cell contains the most mitochondria? | Middle piece |
| ??? is secreted by the hypothalamus to regulate male and female reproductive cycles. | Anterior pituitary |
| The anterior pituitary secretes ??? to regulate female reproductive cycles. | FSH and LH |
| The ??? is the site of implantation. | uterine wall |
| The layer of the uterus that is shed during menstruation is the | endometrium |
| How many chromosomes are found in the zygote? | two sets of 23 totaling 46 |
| This hormone maintains the uterine lining after three months of pregnancy | progesterone |
| A decline in which hormone leads to contractions of the uterus? | progesterone |
| Inflammation of the uterine tube is | salpingitis |
| The word root that means “middle” is | medi |
| This hormone maintains the glandular structure in the ovary that helps maintain pregnancy. | Progesterone |
| The ball of cells in early embryonic development that contains three distinct layers is the | blastula |
| Pregnancy tests detect | pregnancy |
| The hormone from the posterior pituitary that leads to increased uterine contractions during labor and delivery is | oxytocin |
| ??? stimulates the development of glandular tissue in the breast. | Estrogen |
