Answer 1

Key regions of the brain responsible for controlling the autonomic nervous system include the hypothalamus, which serves as the main control center for homeostasis, and parts of the brainstem like the medulla and the pons, which regulate cardiovascular and respiratory activities.

Step-by-step explanation:

The areas of the brain that exert control over the autonomic nervous system are primarily the hypothalamus, medulla, and the pons. The hypothalamus is the main control center for many homeostatic mechanisms in the body, regulating both autonomic and endocrine functions. It is intricately connected with other brain regions, especially through the medial forebrain bundle and the dorsal longitudinal fasciculus, to coordinate sympathetic and parasympathetic pathways. The medulla and the pons, parts of the brainstem, contain control centers for the cardiovascular and respiratory systems, and are also crucial for regulating vital autonomic functions.
