anatomical structure difference between sympathetic nervous system and parasympathetic
The parasympathetic nervous system is one of the two main divisions of the autonomic nervous system (ANS). Its general function is to control homeostasis and the body's rest-and-digest response. The sympathetic nervous system (SNS) is one of two main divisions of the autonomic nervous system (ANS). The sympathetic nervous system is one of the three parts of the ANS. The main purpose of the SNS is to activate the response of the body during stressful situations, including the fight-or-flight mechanism of the body. It is also responsible for regulating many homeostatic mechanisms in the body. 1 Autonomic ganglia can be classified as either sympathetic ganglia and parasympathetic ganglia.  A dorsal root ganglion (or spinal ganglion) is a nodule on a dorsal root of the spine that contains cell bodies of nerve cells (neurons) that carry signals from sensory organs toward the appropriate integration center. The sympathetic nervous system, also part of the autonomic nervous system, originates in the spinal cord; specifically in the thoracic and lumbar regions. It controls the body's fight or flight responses, or how the body reacts to perceived danger. Difference between Sympathetic and Parasympathetic. Tweet. Both the sympathetic nervous system (SNS) and parasympathetic nervous system (PSNS, or occasionally PNS) are part of the autonomic nervous system (ANS or visceral nervous system or involuntary nervous system). Parasympathetic vs. Sympathetic Nervous System. 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 (SNS) controls the body's responses to a perceived threat and is responsible for the fight or flight response. Diffen › Science › Biology › Anatomy. 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 (SNS) controls the body's responses to a perceived threat and is responsible for the fight or flight response. The parasympathetic nervous system is one of the three parts of the ANS. It is responsible for stimulation of rest-and-digest or feed and breed activities that occur when the body is at rest. These activities include sexual arousal, salivation, tearing up, urination, digestion, and defecation. Parasympathetic ganglia are the autonomic ganglia of the parasympathetic nervous system. Most are small terminal ganglia or intramural ganglia, so named because they lie near or within (respectively) the organs they innervate. The exceptions are the four paired parasympathetic ganglia of the head and neck. Parasympathetic ganglia are the autonomic ganglia of the parasympathetic nervous system. Most are small terminal ganglia or intramural ganglia, so named because they lie near or within (respectively) the organs they innervate. Sympathetic ganglia are the ganglia of the sympathetic nervous system. They deliver information to the body about stress and impending danger, and are responsible for the familiar fight-or-flight response.
