GELVOSA]* *SECTION:[BSN-1B] DATE: [SEPTEMBER 16,2024]* *Fill in the blank or provide a short answer.* 1. The gonads produce sex cells, also known as [gametes.] 2. The first portion of the duct system of the male reproductive system is the [epididymis.] 3. The glands that produce a thick, yellowish secretion which nourishes and activates sperm are the [seminal vesicles]. 4. The type of sugar that is found in semen and provides essentially all the energy fuel for sperm is called [fructose]. 5. The enlarged tip of the penis is called the glans penis. 6. The sac of skin that houses the testes outside the body is the [scrotum.] 7. The helmet-like region of the sperm that is similar to a large lysosome and assists in penetration of the egg is called the [acrosome.] 8. The process that streamlines spermatids into sperm is known as [spermiogenesis.] 9. The hormone testosterone is produced by the [Leydig (or interstitial)] cells of the testes. 10. Tiny saclike structures within the ovaries in which oocytes are found are called [follicles.] 11. A mature ovarian follicle that is ready to be ejected from an ovary is called a Graafian follicle. 12. The ducts or tubes responsible for receiving the ovulated oocyte and providing the site for fertilization are the [fallopian (or uterine) tubes.] 13. The finger-like projections that partially surround the ovary at the distal end of each uterine tube are called fimbriae. 14. The narrow outlet of the uterus that protrudes into the vagina is the [cervix.] 15. The ligament that anchors the anterior portion of the uterus is called the [round ligament.] 16. The innermost layer of the uterus is a mucosa layer called the [endometrium]. 17. Burrowing of the fertilized egg into the endometrium lining of the uterus is called [implantation.] 18. The fatty, rounded area overlying the pubic symphysis is the [mons pubis.] 19. The labia majora enclose the region known as the [vestibule,] which contains the external opening of the urethra. 20. The process of creating female gametes is called [oogenesis.] 21. The hormone that promotes a small number of primary follicles within the ovary to grow and mature each month is [follicle-stimulating hormone (FSH).] 22. The ovum has chromosomes. 23. The follicle-cell capsule surrounding an ovulated secondary oocyte is called the [corona radiata.] 24. The hormone produced by the corpus luteum that helps maintain pregnancy is called progesterone. 25. Days 1-5 of the menstrual cycle are the first phase known as the [menstrual phase.] 26. Mammary glands are modified [sweat] glands. 27. The process by which the acrosome membranes of sperm break down is known as the [acrosomal reaction.] 28. A fertilized egg, which represents the first cell of a new individual, is called a [zygote.] 29. The early stage of embryonic development during which rapid mitotic cell divisions occur as the zygote travels down the uterine tube is called [cleavage.] 30. The primary germ layer that gives rise to the nervous system and epidermis of the skin is called the [ectoderm.] 31. The hormone that causes pelvic ligaments and the pubic symphysis to relax, widen, and become more flexible is called [relaxin.] 32. The series of events that expel the infant from the uterus are referred to collectively as [labor.] 33. The first stage of labor is known as the [dilation] stage. 34. The placenta and its attached fetal membranes, expelled from the uterus during the placental stage of labor, are collectively referred to as the [afterbirth.] 35. Individuals who possess both ovarian and testicular tissues are called [hermaphrodites.] 36. The cessation of ovulation and menses for an entire year is called [menopause.] **Alternate Response.

Explain what he should expect after his vasectomy.** 2. **What hormones promote ovulation? Describe how the levels of these hormones change in the days before ovulation.** 3. **List and describe the three stages of labor.** [Dilation: The cervix dilates to 10 cm, contractions increase, and the amnion ruptures. This is the longest stage, lasting 6 to 12 hours.] [Expulsion: The infant passes through the cervix and vagina. This stage lasts up to 2 hours, typically 50 minutes for a first birth and 20 minutes for subsequent births. The normal delivery position is head-first.] [Placental Stage: The placenta is delivered within 15 minutes after birth. All placental fragments must be removed to avoid postpartum bleeding.]
