• B. Brain stem and epithalamus
• C. Corpus callosum and thalamus
• D. Limbic system and hypothalamus

Answer 1

The Correct Option is D

The parts of the human brain involved in the regulation of sexual behavior, expression of excitement, pleasure, rage, fear, etc., are the Limbic system and the hypothalamus. Here is a brief explanation of their roles:

• Limbic System: This system is often referred to as the "emotional brain." It includes structures such as the amygdala, hippocampus, and cingulate gyrus, which are critical in processing emotions, motivation, and memory formation. The limbic system plays a vital role in emotional experiences and behaviors, including pleasure and fear responses.
• Hypothalamus: Positioned below the thalamus, it regulates several essential functions, including endocrine processes via its connection with the pituitary gland. It is directly involved in emotional responses and drives behaviors critical for survival, such as hunger, thirst, and sexual activity. The hypothalamus integrates various signals to control the emotional state and the body's homeostatic balance.
