Read each question carefully and answer to the best of your ability. Refer to the diagram of the synapse provided.
Observe the diagram of a synapse below to answer the following questions.
1. The specialized junction between two neurons where electrical impulses are transmitted is called a .
2. Neurotransmitters are released from the into the synaptic cleft.
3. The neuron that receives the neurotransmitter is called the neuron.
1. Which of the following is NOT a component of a synapse?
Presynaptic terminal
Synaptic cleft
Myelin sheath
Postsynaptic membrane
2. What is the primary function of neurotransmitters in a synapse?
To insulate the axon
To transmit signals across the synaptic cleft
To generate action potentials
To provide structural support to the neuron
1. The presynaptic neuron releases neurotransmitters into the synaptic cleft.
True
False
2. Receptors for neurotransmitters are located on the presynaptic membrane.
True
False
1. Briefly describe the process of neurotransmission at a chemical synapse.
2. Explain the difference between an excitatory and an inhibitory neurotransmitter.
Use the words below to complete the sentences.
1. Neurotransmitters are stored in small sacs called within the presynaptic terminal.
2. After binding to receptors, some neurotransmitters are reabsorbed by the presynaptic neuron through a process called .
3. The binding of neurotransmitters to receptors can cause channels to open, allowing to flow into the postsynaptic neuron.
