Sympathetic: Swedish translation, definition, meaning

The interaction of the postganglionic neurons with the effector organs responsible for creating different activity changes within the organ PREGANGLIONIC AND POSTGANGLIONIC NEURONS. The autonomic pathway, for innervation of smooth muscle or gland always consists of two neurons that synapse in a ganglion (Fig. 3.2). The first neuron carries the nerve impulse from the CNS to the ganglion and is called the preganglionic neuron.
