What is a Synapse?
A synapse is a connection which allows for the transmission of nerve impulses. Synapses can be found at the points where nerve cells meet other nerve cells, and where nerve cells interface with glandular and muscular cells. In all cases, this connection allows for the one-way movement of data. The human body contains trillions of synapses, and at any given time, huge numbers of these connections are active. Understanding the anatomy of a nerve cell can be helpful when learning about synapses. Each nerve cell consists of a cell body, with attached axons and dendrites. These branching structures carry information to and from the cell body. Dendrites bring information in, with the use of receptors on their tips which collect information from other cells. Axons bring information away by sending signals across the synapse between the nerve cell and another cell. In most cases, a synapse is chemical, which means that neurotransmitters are passed along the connection, in contrast with an elec
