Which of the following statements concerning a chemical synapse is true?Question 25Select one:a.Neurotransmitter is released in response to an action potential arriving at the axon hillock.b.Neurotransmitter is actively transported across the synaptic cleft.c.Neurotransmitter binds to its receptors on the postsynaptic membrane.d.The synapse consists of a presynaptic dendrite, a postsynaptic cell and an interstitial space between them (known as the synaptic cleft).e.The synapse consists of a presynaptic dendrite, a postsynaptic neuron and an interstitial space between them (known as the presynaptic cleft).

Which of the following statements about transmission of nerveimpulse is incorrect?(a) Nerve impulse travels from dendritic end towards axonal end(b) At the dendritic end electrical impulses bring about the releaseof some chemicals which generate an electrical impulse at theaxonal end of another neuron(c) The chemicals released from the axonal end of one neuron crossthe synapse and generate a similar electrical impulse in adendrite of another neuron(d) A neuron transmits electrical impulses not only to anotherneuron but also to muscle and gland cells

At a synapse, the neuron that releases the neurotransmitter (sends the signal) is the __________Blank and the neuron that responds to the neurotransmitter (receives the signal) is the __________Blank.Multiple Choiceoligodendrocyte; Schwann cellpostsynaptic neuron; presynaptic neuronpresynaptic neuron; postsynaptic neuronSchwann cell; oligodendrocyte

The chemical signals that diffuse across the synapse are called ____.Question 32Select one:a.neurotransmittersb.dentritesc.thoughtsd.neurons

Consider a neuron-neuron synapse. Match the description with the presynaptic or postsynaptic neuron.Action potential travels away from the synapse via this neuron.Answer 1 Question 15Releases neurotransmitter.Answer 2 Question 15First in the chain of neurons.Answer 3 Question 15Second in the chain of neurons.Answer 4 Question 15

At a synapse, the neuron that responds to the neurotransmitter is the Blank______ neuron.Multiple choice question.postsynapticpresynaptic
