Question

Quizplus · Accepted Answer

The synaptic knob is a tiny bulge at the end of the presynaptic cell, which contains neurotransmitters.

Answer: A
 The presynaptic cell is the neuron that sends the signal across the synapse.

Answer: B
 Neurotransmitters are chemical messengers that are released from the synaptic knob and transmit signals across the synapse.

Answer: C
 The postsynaptic cell is the neuron that receives the signal across the synapse.

Answer: G
 The synaptic cleft is the small gap between the presynaptic and postsynaptic cells that neurotransmitters must cross to transmit the signal.

Answer: F
 Chemical synapses are synapses in which neurotransmitters are used to transmit signals from the presynaptic to postsynaptic cell.

Answer: E
 Electrical synapses are synapses in which electrical signals directly pass from one neuron to another, without the use of neurotransmitters or a synaptic cleft.
