During an accident, the hypothalamus of a person is damaged. Which of the following function/s will be impaired in such a person?

Options

A. Decision making and memory
B. Speech and voluntary movements
C. Regulation of sexual behaviour and synthesis of vasopressin
D. Motor functions and hormonal release of the pineal gland.

Answer

To solve the question regarding the functions that will be impaired in a person with a damaged hypothalamus, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Role of the Hypothalamus**:
- The hypothalamus is a crucial part of the brain that regulates many bodily functions, including the release of hormones from the pituitary gland. It plays a significant role in maintaining homeostasis, regulating temperature, hunger, thirst, sleep, and emotional responses.

2. **Identify Functions Affected by Hypothalamus Damage**:
- The hypothalamus is involved in the regulation of various hormones, including those related to reproductive functions and behaviors. It also synthesizes vasopressin (also known as antidiuretic hormone), which is important for water balance in the body.

3. **Evaluate the Options Provided**:
- **Option 1**: Impaired decision making and memory - This function is primarily associated with the cerebral cortex and not directly with the hypothalamus.
- **Option 2**: Impaired speech and voluntary movements - These functions are controlled by other areas of the brain, such as the Broca's area for speech and the motor cortex for voluntary movements.
- **Option 3**: Regulation of sexual behavior and synthesis of vasopressin - This is directly related to the functions of the hypothalamus, making this option likely correct.

4. **Conclude the Correct Answer**:
- Based on the analysis, the correct answer is **Option 3**: Regulation of sexual behavior and synthesis of vasopressin would be impaired in a person with a damaged hypothalamus.

### Final Answer:
The functions that will be impaired in a person with a damaged hypothalamus include the regulation of sexual behavior and the synthesis of vasopressin.
