Name: neuromast hair cell
Synonyms: neuromast hair cells
Definition: Neuromast hair cell is a hair cell that acts as a sensory receptor of the neuromast; it is morphologically polarized as a result of the relative position of the single kinocilium and the clusters of stereocilia on its apical surface.

Name: synapse
Synonyms: electrotonic synapse, mixed synapse, synaptic junction
Definition: The junction between a nerve fiber of one neuron and another neuron, muscle fiber or glial cell. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane.
