Ответ:

1. Г
4. Б Ретикулярна формація відповідає за емоції людини, рухові реакції, а також за збудження та фільтр несуттєвих сенсорних стимулів

Answer 2

The Brain Region Affected in the Given Symptoms

The brain region that is likely affected when a person experiences respiratory arrest, decreased vascular tone and blood pressure, and irregular heart contractions is the medulla oblongata. The medulla oblongata is located in the brainstem and is responsible for controlling vital functions such as breathing, heart rate, and blood pressure [[1]].

The Role of the Reticular Formation

The reticular formation is a network of neurons located in the brainstem that plays a crucial role in regulating various functions of the central nervous system. However, it does not directly control emotions or motor responses. Instead, it is primarily responsible for arousal, attention, and sleep-wake cycles [[2]].

Functions of the Reticular Formation

The reticular formation is involved in several important functions, including: - Arousal and Consciousness: The reticular formation helps regulate the level of consciousness and alertness. It receives sensory information from various parts of the body and relays it to the cerebral cortex, contributing to wakefulness and maintaining an awake state [[3]]. - Attention: The reticular formation plays a role in filtering sensory information and directing attention to relevant stimuli. It helps to focus on important sensory inputs while filtering out irrelevant or nonessential stimuli [[4]]. - Sleep-Wake Cycles: The reticular formation is involved in the regulation of sleep and wakefulness. It helps to initiate and maintain wakefulness during the day and promotes the transition to sleep during the night [[5]].

Conclusion

In summary, the medulla oblongata is likely the brain region affected in the given symptoms of respiratory arrest, decreased vascular tone and blood pressure, and irregular heart contractions. The reticular formation, on the other hand, is not responsible for emotions or motor responses but plays a crucial role in regulating arousal, attention, and sleep-wake cycles.
