True/False Section Please correcily idensify each of the following statements as tbrue or false Mark "" for srue and h"for false. 1. Impotenc 2. 3. ce means that a male cannot produce "normal" or "physiologically active" spermatozoa Maternal blood actually mixes directly with fetal blood within the placenta during nutrient exchange Both males & females can achieve multiple orgasms if sexual stimulation is maintained or continued beyond the initial orgasm. Ovulated oocytes secrete allurin which functions as a chemotaxic attractant for spermatozosa Females, like males, continue to produce new gametes throughout life -just far less numbers of them. In Prophase I of Meiosis, homologous chromosome pairs line up and can exchange large pieces of 5. 6. DNA in a process called "crossing-over" that increases the variability of gametes. Humans are the only species that use sexual intercourse for more than the production of offspring. Penetration of the oocyte by a sperm cell results immediately in a "wave of depolarization" the spreads 8. around the oocyte knocking off any other spermatozoa this is called a "Fast Block" to polyspermy A developing female fetus retains mesonephric tubules (Wolffian ducts) for her reproductive ducts Pregnancy is maintained initially by hCG (buman chorionic gonadotropin) keeping the Corpues hdcrwm 9. 10. viable and actively secreting progesterone until the placenta can take over. .The largest component of semen is the nutrient secretion (fructose, etc.) from the seminal vesicles 12. 13. Ovulation results from a mid-cycle surge of FSH (Follicle Stimulating Hormone). PSNS mediated release of nitric oxide causes an increase in blood flow into corpus cavernosa bodies within the shaft of the penis creating pressure that essentially closes off venous drainage and makes the penis rigid or erect A female oocyte remains in a state of "suspended animation" (stuck in Metaphase II) and will not finish the process of Meiosis unless fertilized by a sperm. 14. In order to survive, a developing embryo must digest its way into the endometrial lining of the uterus in a process called Implantation 15. 16. 17 18. 19. 20. The extenal genitalia of both genders is identical for almost the first trimester of development. The processes of Capacitation that begins in the epididymis "teaches" sperm to behave like sperm Circumeision is simply the surgical removal of the foreskin (prepuce) from the glans penis The process of Meiosis produces 4 haploid daughter cells that are exactly genetically identical. The Cremaster muscle in gprmaic conds & the Duriar muscl in dhe wall f te crotum play a critical role in maintaining a cooler temperature in the testes for appropriate spermatogenesis.Explanation / Answer
1.(a)The male when not able to produce the normal amount of sperm require to fertilizes ova its called Impotence.
2.(a)The placenta is the only connection between the fetus and the mother so all the nutritional demands of the child is fullfil by the mixture of maternal blood to fetal blood.
3.(b) Female cannot acheive the multiple organism as can male have .
4(a) the Allurin acts as a chemoattractant for spermatozoa.
