Which hormones are present in largest concentration just before ovulation? During which part of the menstrual cycle is the endometrium most prepared to receive an embryo? Which hormones stimulate thickening of the endometrium? Gonadotropic hormones and ovarian hormones regulate the monthly sequence of events that take place within the ovary and uterus. The preovulatory phase begins with menstruation; the postovulatory phase begins after ovulation. Figure 50-14 Endocrine regulation of the menstrual cycle When fertilization does not occur, the menstrual cycle repeats about every 28 days. Note the changes in hormone concentrations that regulate the menstrual cycle.

- The main function of the acrosome reaction is to (a) activate the egg (b) improve sperm motility (c) prevent interspecific fertilization (d) facilitate penetration of the egg coverings by the sperm (e) cause fusion of the sperm and egg pronucleiarrow_forwardAfter ovulation, the secondary oocyte enters the (a) oviduct (b) corpus luteum (c) cervix (d) ovary (e) vaginaarrow_forwardMovement of spermatozoa through this component of the male reproductive pathway (6) occurs during the same phase of sexual activity as which of the following? (A) nitric oxide release (B) movement of sperm through the epididymis (from the head to the tail) (C) release of prostatic secretions (D) movement of sperm through the penile urethra (E) A and B (F) B and C (G) C and D (H) B, C, and Darrow_forward
- Reproductive physiology (human) a) At the time of ovulation, the released ovum (egg) has completed both meiosis I and meiosis II. b) Because the corpus luteum (CL) is rescued from atresia by hCG early in pregnancy, the CL continues to produce progesterone throughout the 9 months of a normal pregnancy. c) Late in the follicular phase, estrogen participates in a positive feedback loop that leads to a surge in luteinizing hormone and ovulation. d) Both (a) and (b) are correct and (c) is incorrect e) Statements (a), (b) and (c) are all correctarrow_forwardQ1 antianxiety drug contain (a)caffeine (b)cocaine (c)amphetamine (d)benzodiazepines Q2 menstrual cycle in primates starts with the (a)menstrual phase (b)luteal phase (c)secretory phase (d)ovulatory phasearrow_forwardIn human beings, the correct sequence of events during reproduction is: (a) gamete formation, fertilisation, zygote, embryo (b) embryo, zygote, fertilisation, gamete formation (c) fertilisation, gamete formation, embryo, zygote (d) gamete formation, fertilisation, embryo, zygotearrow_forward
- Which statement about human reproduction is false?(A) Fertilization occurs in the oviduct.(B) Spermatogenesis and oogenesis require differenttemperatures.(C) An oocyte completes meiosis after a sperm penetrates it.(D) The earliest stages of spermatogenesis occur closest to thelumen of the seminiferous tubules.arrow_forwardIf an egg cell were treated with EDTA, a chemical that bindscalcium and magnesium ions,(A) the acrosomal reaction would be blocked.(B) the fusion of sperm and egg nuclei would be blocked.(C) the fast block to polyspermy would not occur.(D) the fertilization envelope would not form.arrow_forwardWhich of the following statements about reproduction in humans is correct? (a) Fertilisation takes place externally. (b) Fertilisation takes place in the testes. (c) During fertilisation egg moves towards the sperm. (d) Fertilisation takes place in the human female.arrow_forward
