- Which of the following statements is NOT true regarding maternal alcohol consumption, cigarette smoking, and use of illicit drugs during lactation? a. Alcohol passes into breast milk and causes sleepiness in the infant. b. Infants drink slightly more breast milk when the mother consumes up to one alcoholic drink per day. c. To minimize the effects of an occasional alcoholic drink, women should drink after breastfeeding, eat a meal with the drink to reduce alcohol absorption, and wait to breastfeed for several hours after drinking. d. Illicit drugs can be delivered through breast milk and cause irritability, tremors, hallucinations, and even death in infants.arrow_forwardWhich of the following statements about gender development is NOT correct?

To be genetically male, one X chromosome and one Y chromosome are required. d.

Select one: a. Only the inner cell mass cells in a blastocyst are pluripotent. b. The trophoblast has an important role in maintaining the pregnancy, as it prevents the endometrium from shedding. c. As hCG takes over maintaining the endometrium immediately after implantation, the corpus luteum degenerates into the corpus albican. d. All 16 cells in a morula are truly totipotent, meaning that they can become any cells in the human body.arrow_forward

- When the fetus is fully developed and takes up the maximum amount of space in the uterus, the pressure that it inflicts upon the cervix activates stretch receptors to send a signal to the hypothalamus (a structure within the brain). The brain responds by producing oxytocin, which is then released by the pituitary gland (an endocrine organ in the brain). Oxytocin travels through the bloodstream; when it reaches the uterus, it signals through myometrial (uterine smooth muscle) oxytocin receptors. Activation of the oxytocin receptors on myometrial tissue causes a signaling cascade that results in the cell producing prostaglandins that facilitate myometrial contraction (Figure 2).. Contraction of myometrial tissue then reduces the intrauterine space, causing the fully developed fetus to inflict more pressure on the cervix, thus repeating this process until the fetus is delivered. a) Fetal delivery is an example of which type of feedback loop? b) What type of sensory receptor is the…arrow_forwardWhich of the following rows indicates this pregnancy hormone and the correct location of production?
