WebAn exception is with sweat glands, which receive sympathetic innervation but have muscarinic acetylcholine receptors, which are normally characteristic of the parasympathetic nervous system. Another exception is with certain deep muscle blood vessels, which dilate (rather than constrict) with an increase in sympathetic tone.
WebMost of the signals that your sympathetic nervous system sends start in your spinal cord. The signals leave your spinal cord and activate structures called ganglia. Your sympathetic ganglia then send the necessary signals far and wide to different parts of your body. This could include your heart, lungs, arteries, sweat glands and digestive system. WebView 5.

WebMay 17, 2024 · The sympathetic system dilates the pupil of the eye, whereas the parasympathetic system constricts the pupil. In some organs, opposing effects are achieved without dual innervation. For example, the arrector pili muscles, sweat glands, and blood vessels to skeletal muscles and skin are primarily under sympathetic control. WebApocrine sweat glands receive adrenergic sympathetic innervation. Because apocrine sweat glands respond to norepinephrine, they are involved in emotional sweating due to stress, fear, pain, and sexual stimulation. Apocrine sweat glands are larger than eccrine glands, with a 10-fold greater diameter 8).
There are two kinds of neurons involved in the transmission of any signal through the sympathetic system: pre-ganglionic and post-ganglionic. The shorter preganglionic neurons originate in the thoracolumbar division of the spinal cord specifically at T1 to L2~L3, and travel to a ganglion, often one of the paravertebral ganglia, where they synapse with a postganglionic neuron. From there, the long postganglionic neurons extend across most of the body.
