MEDICAL PHYSIOLOGY

Detailed explanation-1: -Activation of the sympathetic nervous system increases heart rate and blood pressure and decreases digestion and blood flow to the skin. Activation of the parasympathetic nervous system decreases heart rate and blood pressure and increases digestion and blood flow to the skin.

Detailed explanation-2: -Doctors often call the parasympathetic nervous system the “rest and digest” side, while the sympathetic is the “fight or flight.”

Detailed explanation-3: -Your brain needs your peripheral nervous system to control those functions. Examples of these processes include your heart rate, breathing, blood pressure and your gut’s digestion of food.

Detailed explanation-4: -Enteric nervous system-is the intrinsic nervous system of the GI tract, containing a mesh-like system of neurons. This system coordinates digestion, secretion, and motility to achieve adequate nutrient absorption.

Detailed explanation-5: -The peripheral nervous system is divided into two main parts: Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands. Somatic nervous system (SNS): Controls muscle movement and relays information from ears, eyes and skin to the central nervous system.
