Synapse
Nervous System Structural feature of unique importance in the nervous tissue is the synapse. A synapse is the anatomical site at which axon terminal processes of one nerve cell establish a functional contact with another nerve cell. At this contact site the membranes of the two cells in contact are separated by a physical space. Special mechanisms operate to transmit signal from one i.e. presynaptic to the other i.e. postpynaptic.
