Formed by tight junctions between adjacent sustentacular cells 19. Smooth muscle that wrinkles scrotal skin; in superficial scrotal fascia 20. Skeletal muscle that raises the testes against the body wall Question 21: Write the correct answer in the space: 21. In mitosis, (two or four) daughter cells are produced. Correct Answer These daughter cells are (haploid or diploid). In meiosis, (two or four) daughter cells are produced. These daughter cells are (haploid or diploid). 22. Correct pathway for flow of sperm from point of origin to outside the body Put the following structures in correct order, using the numbers: 1. Body of epididymis 2. Ductus deferens 3. Efferent ductules 4, Ejaculatory duct 5. External urethral orifice 6. Head of epididymis 7. Membranous urethra 8. Prostatic urethra 9. Rete testis 10. Seminiferous tubule 11. Straight tubule 12.

Q. bulb of vestibule clitoris greater vestibular glands hymen labia majora labia minora mons pubis oogonia ovary oviducts perineum prepuce stratum basalis stratum functionalis vagina vestibule vulva 23. Mucus-producing glands homologous to bulbourethral glands in males 24. Erectile tissue homologous to corpus spongiosum in males 25. Erectile tissue homologous to corpora cavernosa in males 26. Receives penis during sexual intercourse or serves as birth canal 27. Collective name for female external genitalia 28. Site of ova and hormone (estrogens & progesterone) production 29. Membrane that partially closes the vaginal canal 30. Space between labia minora with external urethral & vaginal orifices 31. Fold of skin that covers the glans clitoris 32. Rounded fatty pad that overlies the pubic symphysis in females 33. Site where fertilization normally occurs 34. Diamond-shaped region located between pubic arch anteriorly, coccyx posteriorly, and ischial tuberosities laterally 35. Fetal stem cells that give rise to oocytes 36. Layer of uterine lining that sloughs during menstruation 37. Two outer skin folds covered with hair; homologous to the scrotum 38. Two inner hairless skin folds that enclose the vestibule Matching. A. B. C. D. E. F. G. H. I. J. K. L. corpus luteum estrogens estrogens and progesterones FSH and LH follicular phase luteal phase LH ovulation or ovulatory phase menstrual phase progesterones proliferative phase secretory phase 39. During this phase, an ovum is released from the ovary. 40. This ovarian phase is named for the corpus luteum. 41. This ovarian phase is characterized by the growth of 6-12 primordial follicles, culminating in the formation of one vesicular follicle. 42. The ruptured follicle turns into this endocrine structure. 43. The vesicular follicle ruptures in response to a surge in the levels of this hormone. 44. During the follicular phase, the ovarian follicles produce this hormone. 45. These hormones are produced by the corpus luteum. 46. Growth of ovarian follicles is stimulated by these hormones from the anterior pituitary. 47. This phase of the uterine cycle is characterized by increased vascularization of the functional layer and secretion by the uterine glands. These effects are stimulated by ovarian progesterones. 48. This phase of the uterine cycle is characterized by the sloughing of the functional layer of the endometrium. It is caused by a drop in the levels of the ovarian hormone, progesterone. 49. During this phase of the uterine cycle, the regrowth of the functional endometrium is stimulated by rising levels of ovarian estrogens. Matching. A. alveoli B. areola C. lactiferous sinus D. lobes E. lobules F. nipple 50. Milk is produced in this part of the mammary gland. 51. Mammary gland divided internally into 15-20 of these structures; each is compound alveolar gland with duct opening at nipple 52. Dilated region of lactiferous duct; milk accumulates here during nursing 53. Subdivision of a lobe; composed of clusters of tiny alveoli 54. Dark pigmented ring of skin that surrounds a nipple
