C14 analyse the functional inter-relationships of the structures of the male reproductive system

C15 analyse the functional inter-relationships of the structures of the female reproductive system

1. identify and give functions for each of the following:

|Letter on Diagram |Structure |Function |

|Not shown on |scrotum | |

|diagram | | |

| |urethra | |

| |epididymis | |

| |ductus (vas) deferens | |

| |prostate gland | |

| |Cowper’s glands | |

| |seminal vesicles | |

|Not labeled on |penis | |

|diagram | | |

| |Testes (testicle) | |

| |seminiferous tubules | |

|Not shown on |interstitial cells |(between the seminiferous tubules) |

|diagram | | |

[pic][pic]

2. describe the path of sperm from the seminiferous tubules to the urethral opening.

3. list the components seminal fluid (as contributed by the Cowper’s glands, prostate gland, and seminal vesicles), and describe the functions of each component

|Gland |Component of Seminal Fluid |Function |

|Cowper’s (Bulbourethral) | | |

|Prostate | | |

|Seminal Vesicles | | |

4. identify the tail (flagellum), midpiece, head, and acrosome of a mature sperm and state their functions

|Letter on diagram |Structure |Function |

| |Tail (flagellum) | |

| |Midpiece | |

| |Head | |

| |Acrosome | |

5. describe the functions of testosterone.

6. describe the homeostatic regulation of testosterone levels by the hypothalamus, anterior pituitary, and testes and complete the flow chart below.

7. identify and give functions for each of the following – you will not have to use all the letters on the diagram

|Letter on Diagram |Structure |Function |

| |ovaries | |

| |follicles | |

| |corpus luteum | |

| |oviducts (fallopian tubes) | |

| |uterus | |

|Not shown |endometrium |Where is it? |

| | |What does it do? |

| |cervix | |

| |vagina | |

| |clitoris | |

[pic]

8. describe the functions of estrogen

9. describe the sequence of events in the ovarian cycle, with reference the follicular phase, ovulation, and the luteal phase

OVARIAN CYCLE: REMEMBER: DAY 1 is the FIRST day of woman’s period.

|Stage |Day (s) |What are the hypothalamus and a.pituitary doing? |What is happening in the ovary and what is it producing? |

|Follicular phase |1 ( | | |

| | | | |

| | | | |

| | | | |

| | | | |

|Ovulation | | | |

| | | | |

| | | | |

|Luteal Phase | | | |

| | | | |

| | | | |

| | | | |

| | | | |

10. describe the sequence of events in the uterine cycle, with reference to menstruation, the proliferative phase, and the secretory phase

UTERINE CYCLE:

|Stage |Day (s) |What are the hypothalamus and a.pituitary doing? |What is happening in the uterus and what is it producing? |

|Menstruation |1 ( | | |

| | | | |

| | | | |

| | | | |

| | | | |

|Proliferative Phase | | | |

| | | | |

| | | | |

| | | | |

| | | | |

| | | | |

|Secretory Phase (assume | | | |

|NO PREGNANCY) | | | |

| | | | |

| | | | |

| | | | |

| | | | |

11. describe the control of the ovarian and uterine cycles by hormones including gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen, and progesterone and complete the flow chart to the right.

12. describe the hormonal changes that occur as a result of implantation, including production of human chorionic gonadotropin (HCG) to maintain the corpus luteum and increased production of progesterone by the corpus luteum

13. describe a positive feedback mechanism involving oxytocin
