Which among the following is not a neural action controlled by the part of human brain labelled 'X' in the figure above?
Which among the following is not a neural action controlled by the part of human brain labelled 'X' in the figure above?

Options
The part of the human brain labelled 'X' in the figure above is the hypothalamus. The hypothalamus controls various neural actions such as salivation, vomiting, and blood pressure. However, hunger is controlled by the lateral hypothalamus, which is a different part of the brain. Therefore, the correct answer is option B) Hunger.
Marking Scheme
- 1Salivation
- 2Vomiting
- 3Blood Pressure
Hint
The hypothalamus is a small region at the base of the brain that plays a crucial role in controlling various bodily functions.
Quick Oral Answer
The hypothalamus is a small region at the base of the brain that plays a crucial role in controlling various bodily functions, including hunger, thirst, body temperature, and hormone balance. It also regulates the autonomic nervous system, which controls involuntary actions such as heart rate, blood pressure, and digestion. The lateral hypothalamus is responsible for controlling hunger and satiety, while the ventromedial hypothalamus is involved in regulating body weight and appetite. The hypothalamus also produces several important hormones, including oxytocin and vasopressin, which play roles in social behavior, stress response, and fluid balance. Overall, the hypothalamus is a critical component of the brain's regulatory systems, and its dysfunction can lead to a range of disorders, including obesity, diabetes, and sleep disorders.
Analysis & Explanation
The question requires the student to identify the neural action that is not controlled by the part of the human brain labelled 'X' in the figure above. The correct answer is option B) Hunger, as hunger is controlled by the lateral hypothalamus, which is a different part of the brain. The other options, salivation, vomiting, and blood pressure, are all controlled by the hypothalamus. This question requires the student to have knowledge of the different parts of the brain and their functions, as well as the ability to analyze and interpret the information provided in the figure.
