Lab 8: Reproductive System I. Anatomy of the male & female reproductive systems A. The Female Reproductive System For practice – fill in the blanks (to reinforce visible body work). Highlight the structures that you can see on the models available to you. Word bank: uterine tube, infundibulum, ovary, fundus, vagina, ovarian ligament, uterus, cervix, fimbriae, perimetrium, myometrium, endometrium Word bank : bladder, urethra, clitoris, uterus, ovary, cervix, rectum, vagina, labium minora, labium majora
Word bank: Primordial follicles, primary follicle, secondary follicle, Mature (Graafian) follicle, Secondary oocyte, degenerating follicle (corpus luteum), corpus albicans Q1) Circle the step that represents ovulation in the diagram above. Q2) Endometriosis is a relatively common disease, affecting about 10% of reproductive females world- wide. What is endometriosis? Where do the cells that grow abnormally originate from?Q Q3) Examine the ovary slide. Which structures can you identify from above on this slide? List them: B. The Male Reproductive System Word bank: Vas deferens, bladder, seminal vesicle, ejaculatory duct, urethra (prostatic), perineal muscles surrounding anus, spongy urethra, membranous urethra, testis, epididymis, scrotum, corpus cavernosum, corpus spongiosum
Tracing the journey of a sperm. Draw arrows on the diagrams below to trace the journey of sperm from the site of spermatogenesis in the testes to the point of fertilization in the female reproductive tract. List the organs and structures that the sperm travels through below the diagrams. Q9) List the organs the sperm travels through from the testes until it leaves the male reproductive tract: Draw arrows on the diagram below to trace the journey of the sperm as it enters the female reproductive tract until it reaches the egg. Next, use a contrasting color to trace the journey of the fertilized egg from fertilization to implantation in the uterine wall.
Q10) List the organs the sperm travels through on its journey through the female reproductive tract. Circle where fertilization occurs: Q11) List the organs the fertilized egg travels through on its journey to implantation: II. Contraceptive Methods Note that there are a variety of devices including barrier methods, hormonal methods, spermicidal methods, and even methods that prevent embryo implantation. Take a look at each contraceptive device (you may need to read the instructions), determine how the device prevents pregnancy, and locate the point in the human reproductive tract where it stops the process of reproduction (it may be in the male or female system!). Use contrasting colored pencils to indicate on the diagrams in activity 5 where the sperm, egg, or zygote would be stopped. Contraceptive How it Location in the Advantages Disadvantages Potential Device prevents human Side pregnancy. reproductive Effects tract where it takes effect. ** If you have questions or concerns about contraception or prevention of sexually transmitted diseases, visit the Health Services in room 2126 (near the Bookstore) or call (650) 949-7243.
- Imagine you are a physician working with a patient. What might you consider when advising your patient on contraceptive options?
- Read the following case-studies and with your group, decide which birth control method would be the best choice for each patient. Why did you pick that method? a. Stacy is in a mutually monogamous relationship. Because of an underlying medical condition, she cannot use any hormonal birth control method. She is looking for a method that will protect her from pregnancy for the next 5 years, minimum. What would be a good method for her? b.
