The division of the ANS that prepares the body for activity and stress is the_____division.
(a) sympathetic
(b) parasympathetic
(c) craniosacral
(d) intramural
(e) somatomotor

Verified step by step guidance

1. Step 1: Understand that the Autonomic Nervous System (ANS) has two main divisions: the sympathetic and parasympathetic divisions, each with distinct roles in regulating body functions.
2. Step 2: Recall that the sympathetic division is responsible for preparing the body for 'fight or flight' responses, which involve increased heart rate, dilated pupils, and energy mobilization during stress or activity.
3. Step 3: Recognize that the parasympathetic division generally promotes 'rest and digest' activities, helping the body conserve energy and maintain homeostasis during restful states.
4. Step 4: Identify that the terms 'craniosacral' and 'intramural' refer to anatomical origins or locations of parasympathetic neurons, not the division responsible for stress response.
5. Step 5: Conclude that the division of the ANS that prepares the body for activity and stress is the sympathetic division.

Key Concepts

Autonomic Nervous System (ANS)

The ANS is a part of the peripheral nervous system that controls involuntary body functions such as heart rate, digestion, and respiratory rate. It operates automatically without conscious control and is divided into two main branches: sympathetic and parasympathetic.

Sympathetic Division

The sympathetic division of the ANS prepares the body for 'fight or flight' responses during stress or physical activity. It increases heart rate, dilates airways, and redirects blood flow to muscles, enabling the body to respond quickly to emergencies.

Parasympathetic Division

The parasympathetic division promotes 'rest and digest' activities, conserving energy by slowing the heart rate and enhancing digestion. It counterbalances the sympathetic division to maintain homeostasis during relaxed states.
