_________and ____________are involved in regulation of sexual behaviour,

Options

A. Cerebral cortex and posterior pituitary
B. Corpora quadrigemina and pons
C. Hypothalamus and limbic system
D. Hypothalamus and medulla oblongta

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks for two parts of the nervous system that are involved in the regulation of sexual behavior.

2. **Analyze the Options**: The options provided include:
- Cerebral cortex and posterior pituitary
- Corporeal quadrigemina and pons
- Hypothalamus and limbic system
- Medulla oblongata

3. **Evaluate Each Option**:
- **Cerebral Cortex and Posterior Pituitary**: The cerebral cortex is involved in higher-order brain functions and neuron integration, while the posterior pituitary mainly releases hormones like oxytocin related to childbirth, not sexual behavior.
- **Corporeal Quadrigemina and Pons**: These structures are primarily involved in visual reflexes and are not directly related to sexual behavior.
- **Hypothalamus and Limbic System**: The hypothalamus is known as the master gland and plays a crucial role in regulating various hormones, including those related to sexual behavior. The limbic system is associated with emotions and sexual excitement.
- **Medulla Oblongata**: This part of the brain is responsible for autonomic functions such as heartbeat and breathing, and is not involved in sexual behavior.

4. **Select the Correct Answer**: Based on the analysis, the correct answer is the **hypothalamus and limbic system**, as they are directly involved in the regulation of sexual behavior.

5. **Final Answer**: Hypothalamus and limbic system are involved in regulation of sexual behavior.
