Question 1 of 5

Which of the following neurotransmitters is associated with the feeling of happiness and well-being?

Correct Answer: B

Rationale: The correct answer is B: Serotonin. Serotonin is associated with feelings of happiness and well-being because it helps regulate mood, emotions, and sleep. Low levels of serotonin have been linked to depression and anxiety. Dopamine (A) is associated with pleasure and reward, GABA (C) is an inhibitory neurotransmitter that helps reduce anxiety, and Acetylcholine (D) is involved in muscle movement and memory. Serotonin is the most relevant neurotransmitter for happiness and well-being due to its specific role in regulating mood and emotions.

Question 2 of 5

Which structure in the body is responsible for detecting light and converting it into signals for the brain?

Correct Answer: B

Rationale: The correct answer is B: Retina. The retina is a layer of light-sensitive cells located at the back of the eye that detects light and converts it into signals for the brain through the optic nerve. The iris (A) controls the amount of light entering the eye, the lens (C) helps to focus light onto the retina, and the pupil (D) regulates the amount of light entering the eye, but they do not convert light into signals for the brain like the retina does.

Question 3 of 5

Which of the following neurotransmitters is associated with the feeling of happiness and well-being?

Correct Answer: B

Rationale: The correct answer is B: Serotonin. Serotonin is associated with feelings of happiness and well-being because it helps regulate mood, emotions, and sleep. Low levels of serotonin have been linked to depression and anxiety. Dopamine (A) is associated with pleasure and reward, GABA (C) is an inhibitory neurotransmitter that helps reduce anxiety, and Acetylcholine (D) is involved in muscle movement and memory. Serotonin is the most relevant neurotransmitter for happiness and well-being due to its specific role in regulating mood and emotions.

Question 4 of 5

Which of the following organs is responsible for producing digestive enzymes?

Correct Answer: B

Rationale: The correct answer is B: Pancreas. The pancreas produces digestive enzymes such as amylase, lipase, and proteases that help break down carbohydrates, fats, and proteins in the small intestine. The liver (A) produces bile but not digestive enzymes. The gallbladder (C) stores bile produced by the liver. The esophagus (D) is responsible for transporting food from the mouth to the stomach, not for producing digestive enzymes.

Question 5 of 5

Which part of the brain is responsible for voluntary muscle movements?

Correct Answer: B

Rationale: The correct answer is B: Cerebrum. The cerebrum is responsible for voluntary muscle movements as it houses the motor cortex, which controls voluntary movements. The medulla oblongata (A) controls involuntary functions like breathing and heart rate. The hypothalamus (C) regulates body temperature, hunger, and thirst. The thalamus (D) serves as a relay station for sensory information. Therefore, the cerebrum is the correct choice for voluntary muscle movements.
