Check Point g Synapse is a small gap separating neurones Synapses consist of: presynaptic ending (where neurotransmitters are made) post synaptic ending (has neuroreceptors in the membrane) synaptic cleft Action potentials cannot cross the synaptic cleft Nerve impulse is carried by neurotransmitters.
The synapse is a small gap separating neurons. The synapse consists of: a presynaptic ending that contains neurotransmitters, mitochondria and other cell organelles, a postsynaptic ending that contains receptor sites for neurotransmitters and, a synaptic cleft or space between the presynaptic and postsynaptic endings. It is about 20nm wide. An action potential cannot cross the synaptic cleft between neurones. Instead the nerve impulse is carried by chemicals called neurotransmitters. These chemicals are made by the cell that is sending the impulse (the pre-synaptic neurone) and stored in synaptic vesicles at the end of the axon.
