2 Νοε 2023 · The sympathetic nervous system is part of the autonomic nervous system, along with its counterpart, parasympathetic nervous system. The origin of the sympathetic nervous system is found within the thoracic and lumbar segments of the spinal cord also known as the thoracolumbar division (T1 to L2,3).
The autonomic nervous system itself consists of two parts: the sympathetic nervous system and the parasympathetic nervous system. Some authors also include sensory neurons whose cell bodies lie in the periphery (for senses such as hearing) as part of the PNS; others, however, omit them.
The sympathetic nervous system is a part of the autonomic nervous system (ANS) that helps regulate the body's involuntary functions such as breathing, digestion, heart rate, and blood pressure.

It increases heart rate, dilates pupils, and inhibits digestion, among other functions, to mobilize the body’s resources for immediate action.
1 Μαΐ 2022 · The sympathetic nervous system has long served as a paradigm for neurobiologists to understand the molecular and cellular mechanisms governing neuron survival, axon growth and innervation of peripheral targets during development.
