Question
Chapter 16, Problem 1TY
Summary Introduction
Introduction:
A male sperm has a flagellum that gives the sperm the ability to move forward. The midpiece of the sperm contains mitochondria that provide power to the tail to move forward. The acrosome is that part of the sperm that penetrates the ovum during fertilization.

Which of the following structures from the male reproductive system has no comparable structure in the female reproductive system? Select one: a. Sertoli cells b. Testes c. Seminal vesicles d. Vas deferensarrow_forwardHow can PID (pelvic inflammatory disease) lead to infertility in women? Select one: a. PID can lead to scar tissue developing on the Fallopian tube. This prevents the egg and the sperm from meeting, causing infertility. b. PID prevents the endometrium from forming. There is not enough material for the fertilized egg to implant itself. c. PID leads to scar tissue on the corpus luteum. This disrupts ovulation. d. PID affects the cervix. This causes the cervix to swell, decreasing the chance a sperm could pass into the uterus.arrow_forwardWhich of the following statements about oocytes and ovulation is correct? a. The production of primary oocytes continues in women from the onset of puberty until the onset of menopause. b. Meiotic divisions are complete at the time of ovulation. c. At ovulation, the structure released from the follicle includes a secondary oocyte and polar body. d. All of these statements are correctarrow_forward
- Which of the following statements does NOT correctly describe the similarities and differences between male and female reproductive systems? Select one: a. Millions of mature sperm are produced on a daily basis, whereas single mature ovum is released every 28 days. b. Meiosis is completed in eggs after fertilization begins, whereas a mature sperm has completed meiosis prior to fertilization. c. Eggs and sperm contain exactly half of the genetic material of a normal somatic cell. Many zygotes with an abnormal number of genetic material often do not successfully implant. d. Eggs and sperm can survive for 3 to 5 days in the Fallopian tubes.arrow_forwardthe barrier seperates the spermatocytes dividing by meiosis from exposing their unique antigens to the immune system. a. blood-brain barrier b. blood-testes barrier c. blood-vas deferens barrierarrow_forwardWhich of the following statements is NOT a role of follicle stimulating hormone (FSH) in the male reproductive system? a.
