April-October (High Season): you need at least 5 nights in Santorini as you will spend lots of time on the beaches. November-March (Low Season): you need at least 3 nights in Santorini and do other things. Ideal: 10 days in Santorini during the best time of the year for the island. Over 3 nights in Greece: at least 50% of your time in Greece should be spent in Santorini and at least 25% in Mykonos. Less than 3 nights in Greece: 2 nights Santorini and 1 night Athens if you are flying through Athens or 3 nights only in Santorini if you are flying directly to Santorini.
The postganglionic neurons of sweat glands release acetylcholine for the activation of muscarinic receptors. The chromaffin cells of the adrenal medulla are analogous to post-ganglionic neuronsâthe adrenal medulla develops in tandem with the sympathetic nervous system and acts as a modified sympathetic ganglion.
In the sympathetic nervous system and other components of the peripheral nervous system, these synapses are made at sites called ganglia. The cell that sends its fiber is called a preganglionic cell, while the cell whose fiber leaves the ganglion is called a postganglionic cell.he first cell (the presynaptic cell) sends a neurotransmitter across the synaptic cleft where it activates the second cell (the postsynaptic cell). The message is then carried to the final destination. Presynaptic nerves' axons terminate in either the paravertebral ganglia or prevertebral ganglia.
