Question
22. In males, FSH (follicle stimulating hormone) is necessary for normal sperm production 23. While the ovary is in its luteal phase the uterus in its proliferative phase 24. Of the hormones of the adrenal medulla responsible for increasing blood pressure, epinephrine is A. True B. False A. True B. False total most effective in increasing cardiac output while norepinephrine is most effective in increasing peripheral resistance. A. True B. False 25. Prolonged exposure to cold environments may cause an increase in thyroid hormone levels A. True B. False 26. Interstitial cell stimulating hormone (iCSH) promotes an increase in testosterone production in males A. True B. False 27. If an ovum is fertilized, the maternal corpus luteum remains a source of estrogen and progesterone throughout the entire pregnancy. A. True B. False 28. A fertilized ovum will normally implant in the endometrial lining of the uterus within two hours A. True B. False following ovulation 29. Generally, insulin is needed at meal time while glucagon is needed between meals 30. In general, strength exercises promote development of skeletal muscle while endurance exercises A. True B. False promote development of cardiac muscle. A. True B. False ow twitch red muscle fibers are adapted for strength exercises of short duration A. True B. False Radiation refers to the process of heat exchange involving direct contact between two objects A. True B. FalseExplanation / Answer
22.(TRUE): FSH in males is required for the determination of Sertoli cell number, and for induction and maintenance of normal sperm production.
23.FALSE: the ovarian luteal phase is the final phase of the ovarian cycle and it corresponds to the secretory phase of the uterine cycle
24.TRUE
25.True: It has been observed that exposure to cold stimulates the hypothalamic-pituitary-thyroid axis and increases the release of TRH (Thyrotropin-releasing hormone (TRH)) from hypothalamus
26.TRUE In males, interstitial cell-stimulating hormone (ICSH), it stimulates Leydig cell production of testosterone
27FALSE: corpus luteum serves as the source of estrogen and progesterone only for the first seven weeks of pregnancy after which placenta takes over as the corpus luteum regresses
28FALSE: Implantation of the fertilized ovum occurs about 5-6 days after entering the uterine cavity and 7 to 10 days after ovulation.
29. True: during meals as the blood glucose levels rise, insulin is secreted to maintain the blood glucose levels from rising n, whereas between meals when the glucose level begins to drop, glucagon is released to maintain the blood glucose levels from going too low
30.FALSE: Endurance exercises promote growth of skeletal muscles also
31FALSE: Slow-twitch muscles help enable long-endurance activities such as distance running, while fast-twitch muscles are involved with short-term activities like sprinting
32: FALSE: radiation involves emission or transmission of energy in the form of waves or particles through a material medium.Conduction is the process of transmission of heat between two objects in contact
