Final answer:
Autonomic motor neurons are divided into the sympathetic and parasympathetic divisions, which are responsible for the body's 'fight-or-flight' and 'rest-and-digest' responses, respectively.Option 1 is the correct answer.
Step-by-step explanation:
The autonomic motor neurons are subdivided into the sympathetic and parasympathetic divisions. These two divisions are key components of the autonomic nervous system (ANS), which is part of the peripheral nervous system (PNS). The sympathetic division is responsible for the body's 'fight-or-flight' response during stressful situations, increasing heart rate, blood pressure, and energy supplies. Conversely, the parasympathetic division promotes the 'rest-and-digest' state, conserving energy and lowering the heart rate and blood pressure. Both divisions work together to maintain homeostasis in the body's involuntary functions such as heart rate, digestion, and respiratory rate.
The autonomic nervous system (ANS), a component of the peripheral nervous system (PNS), intricately governs involuntary physiological functions. This system comprises two divisions—the sympathetic and parasympathetic—which collectively regulate the body's responses to varying stimuli, contributing to overall homeostasis. The sympathetic division, often associated with the 'fight-or-flight' response, orchestrates physiological changes like heightened heart rate, increased blood pressure, and elevated energy mobilization during stress. In contrast, the parasympathetic division induces the 'rest-and-digest' state, fostering energy conservation and reducing heart rate and blood pressure.
Together, these divisions harmonize to sustain equilibrium in essential functions such as heart rate, digestion, and respiratory rate, ensuring adaptive responses to diverse environmental and internal cues.
