Sympathetic and parasympathetic nervous system are two main parts of the autonomic nervous system. Parasympathetic nervous system has no effect on the glycogen breakdown. The parasympathetic nervous system function is to respond to the body s relaxation resting and feeding state. The parasympathetic nervous system pns controls homeostasis and the body at rest and is responsible for the body s rest and digest function.
The sympathetic nervous system function is to prepare the body to deal with conditions of fear and stress that respond through a network of interconnected neurons. Difference between sympathetic and parasympathetic nervous system the sympathetic nervous system prepares the body for the fight or flight response during any potential danger. The sympathetic nervous system releases the hormones epinephrine and nor epinephrine that accelerate the heart rate while the parasympathetic nervous system releases acetylcholine the hormone that slows down the heart rate. Nervous system consists of central nervous system and peripheral nervous system.
The parasympathetic nervous system is composed of cranial and spinal nerves. The main difference between sympathetic and parasympathetic nervous system is that sympathetic nervous system prepares the body for an intense physical activity whereas parasympathetic nervous system relaxes the body by inhibiting high energy functions. Peripheral nervous system is divided into somatic and autonomic nervous system. On the other hand the parasympathetic nervous system inhibits the body from overworking and restores the body to a calm and composed state.
