Human Growth and Development Exam 1
1. What is the function of the corpus luteum?
- A. is where fertilization usually takes place
- B. secretes hormones that prepare the lining of the uterus to receive a fertilized ovum
- C. is one of two long, thin structures that lead to the hollow, softly lined uterus
- D. is one of two walnut-sized organs located deep inside a woman's abdomen
Correct answer: B
Rationale: The correct answer is B. The corpus luteum is a temporary endocrine structure in the ovary that forms after ovulation. It secretes hormones, particularly progesterone, which help prepare the uterine lining for possible implantation of a fertilized ovum. This process is crucial for maintaining a potential pregnancy. Choices A, C, and D are incorrect. Choice A is inaccurate as fertilization typically occurs in the fallopian tubes. Choice C describes the fallopian tubes, not the corpus luteum. Choice D refers to the ovaries, not specifically the corpus luteum.
2. Sigmund Freud constructed his psychosexual theory __________.
- A. on the basis of his adult patients' memories of painful childhood events
- B. by conducting studies of animal behavior
- C. on the basis of interviews with institutionalized children and adolescents
- D. by carefully observing his own children
Correct answer: A
Rationale: Sigmund Freud constructed his psychosexual theory on the basis of his adult patients' memories of painful childhood events. Freud believed that events in early childhood had a significant impact on an individual's development and personality. He used his patients' recollections of childhood experiences to develop his theories on psychosexual development. Choice B is incorrect as Freud did not base his theory on studies of animal behavior. Choice C is incorrect as Freud's theory was not solely based on interviews with institutionalized children and adolescents. Choice D is incorrect as Freud did not construct his theory by observing his own children.
3. According to Erikson, if the psychological conflict of adolescence is resolved negatively, a young person experiences __________.
- A. mistrust
- B. isolation
- C. inferiority
- D. role confusion
Correct answer: D
Rationale: Erikson's theory of psychosocial development states that during adolescence, individuals face the conflict of identity vs. role confusion. If this conflict is resolved negatively, adolescents experience role confusion. Role confusion occurs when adolescents fail to develop a clear sense of identity, leading to uncertainty about their future roles. Choices A, B, and C are incorrect because they correspond to earlier stages of Erikson's stages of psychosocial development (mistrust corresponds to infancy, isolation to early adulthood, and inferiority to middle childhood), not adolescence.
4. Which Apgar criterion can be more difficult to apply to newborns of all races?
- A. pink color
- B. reflex irritability
- C. limp muscle tone
- D. strong breathing
Correct answer: D
Rationale: Among the Apgar criteria, the pink color (choice A), reflex irritability (choice B), and limp muscle tone (choice C) are relatively easy to assess in newborns of all races. However, the criterion that can be more difficult to apply to newborns of all races is strong breathing (choice D). This is because evaluating the strength of a newborn's breathing can be more subjective and require careful observation. Unlike the other criteria that have more visible and objective indicators, assessing the strength of breathing might vary based on the observer's interpretation, making it more challenging to apply universally.
5. By the end of Greta's first month of pregnancy, her embryo __________.
- A. can sense its world
- B. is about ¼ inch long
- C. can suck its thumb
- D. can curl its toes
Correct answer: B
Rationale: By the end of Greta's first month of pregnancy, her embryo is about ¼ inch long. During the first month of pregnancy, the embryo is in the very early stages of development, and its size is typically around ¼ inch as it continues to grow and develop in the uterus. Choices A, C, and D are incorrect because sensory abilities like sensing the world, sucking thumb, and curling toes develop later in the pregnancy as the embryo progresses through different stages of development.
