1. What is the term for a fluid-filled sac in which the baby floats until just before it is born?

• A. Amnion
• B. Placenta
• C. Umbilical cord
• D. Embryo

Correct answer: A

Rationale: The correct answer is A: Amnion. The amnion is a fluid-filled sac that surrounds and protects the developing fetus in the womb. It acts as a cushion, maintaining a stable temperature and protecting the fetus from external pressure. Choices B, C, and D are incorrect because the placenta is an organ that provides nutrients and oxygen to the fetus and removes waste products, the umbilical cord connects the fetus to the placenta to facilitate nutrient exchange, and an embryo is an early stage of development before it becomes a fetus.

2. Freud's psychosexual stage that occurs between the ages of 3 and 5 and includes the Oedipal period is the _________ stage.

• A. Oral
• B. Anal
• C. Phallic
• D. Genital

Correct answer: C

Rationale: The correct answer is C: Phallic. Freud's psychosexual stage that occurs between ages 3 and 5 and includes the Oedipal period is the phallic stage. This stage is characterized by the Oedipus complex for boys and the Electra complex for girls. Choices A, B, and D are incorrect because the oral stage typically occurs during the first year of life, the anal stage occurs around ages 2 to 3, and the genital stage is the final stage in Freud's theory of psychosexual development.

3. The site of chemical communication in the brain is the ________.

• A. neuron
• B. synapse
• C. axon
• D. dendrite

Correct answer: B

Rationale: The synapse is the correct answer. It is the site where communication between neurons occurs through the release and reception of neurotransmitters. Choice A, neuron, is incorrect as it is the cell itself rather than a specific site of communication. Choice C, axon, is also incorrect as it is a part of the neuron that transmits signals away from the cell body. Choice D, dendrite, is not the correct answer either, as dendrites receive signals from other neurons but do not release neurotransmitters for communication.

4. How does the concept of neural plasticity relate to recovery from brain injuries?

• A. Neural plasticity means the brain cannot recover from injuries.
• B. Neural plasticity allows the brain to recover and reorganize after injuries.
• C. Neural plasticity refers to the brain's inability to change after injury.
• D. Neural plasticity is a myth.

Correct answer: B

Rationale: Neural plasticity allows the brain to recover and reorganize after injuries. It is the brain's ability to adapt and change, forming new connections or reorganizing existing ones to compensate for damage. Choice A is incorrect as neural plasticity enables recovery. Choice C is incorrect as neural plasticity involves the brain's capacity to change. Choice D is incorrect as neural plasticity is a well-established phenomenon in neuroscience.

5. Defense mechanisms ________.

• A. make a person feel more anxious and have more problems, as they begin to act defensively.
• B. are strategies the id uses to try to achieve its desires.
• C. are conscious, intentional attempts to cope effectively with an anxiety-producing event.
• D. help a person feel less anxious, but because they usually work by distorting reality, they are not always adaptive.

Correct answer: D

Rationale: The correct answer is D because defense mechanisms aim to reduce anxiety but can lead to distortion of reality, making them not always beneficial. Choice A is incorrect as defense mechanisms are meant to reduce anxiety, not increase it. Choice B is incorrect because defense mechanisms are not strategies of the id specifically. Choice C is incorrect as defense mechanisms are often unconscious and not always intentional.
