Quizplus · Accepted Answer

A neurotransmitter is a chemical that carries a nerve impulse across a synaptic cleft.

Answer: A
 The presynaptic cell is the neuron that releases the neurotransmitter into the synaptic cleft.

Answer: C
 The postsynaptic cell is the neuron that receives the neurotransmitter across the synaptic cleft.

Answer: D
 The synaptic knob (also called axon terminal) is the swollen end of the presynaptic cell that contains neurotransmitters.

Answer: G
 The synaptic cleft is the small gap between the presynaptic and postsynaptic cells across which neurotransmitters travel.

Answer: F
 A chemical synapse is a type of synapse in which a neurotransmitter is used to transmit signals between neurons.

Answer: E
 An electrical synapse is a type of synapse in which electrical signals are used to transmit signals between neurons. This is not directly related to the definition of a neurotransmitter.
