Synapse meaning

The definition of a synapse is the junction between two neurons or nerve cells where there is a small gap that neurotransmitters help nerve impulses to cross.

The junction across which a nerve impulse passes from an axon terminal to a neuron, muscle cell, or gland cell.

The minute space between a nerve cell and another nerve cell, a muscle cell, etc., through which nerve impulses are transmitted from one to the other.

The junction across which a nerve impulse passes from an axon terminal to a neuron, muscle cell, or gland cell.

The small junction across which a nerve impulse passes from one nerve cell to another nerve cell, a muscle cell, or a gland cell. The synapse consists of the synaptic terminal , or presynaptic ending, of a sending neuron, a postsynaptic ending of the receiving cell that contains receptor sites, and the space between them (the synaptic cleft ). The synaptic terminal contains neurotransmitters and cell organelles including mitochondria. An electrical impulse in the sending neuron triggers the migration of vesicles containing neurotransmitters toward the membrane of the synaptic terminal. The vesicle membrane fuses with the presynaptic membrane, and the neurotransmitters are released into the synaptic cleft and bind to receptors of the connecting cell where they excite or inhibit electrical impulses.
