Which of the following statements about synapses is true

Neurotransmitters diffuse across the synapse (the gap) and bind with receptor molecules on the membrane of the next neuron

B Synapse is a small gap that occurs between the axon of one neuron and dendrite of the next neuron C Nerve impulse reaches the synapse at the end of a neuron, it cannot pass directly to the next one D All of the above Open in App Verified by Toppr

A) This statement is true because the usual transport of impulse in nerves when separated by a synapse is through the neurotransmitter passing into the synapse in the form of vesicles and these vesicles combine with the membrane of next neuron and release the substances into the neuron crating active potential.

B) synapse is defined as the gap between two neurons that is from axon terminal of one neuron to dendrites of other. so this statement is true.

C) Nerve impulses when passing in a neuron are in the form of electrical impulses. But to pass through the synapse they need to be converted into chemical impulses.So, this statement is true.

So, the correct option is D. Was this answer helpful? Similar Questions

Which of the following statements are incorrect?
(i) When an impulse travels along a myelinated neuron, it leaps over the myelin sheath from one node to the next.
(ii) At chemical synapse there is continuity between the presynaptic and postsynaptic neurons provided by the gap junctions.
(iii) Neurotransmitters are chemicals that are released from postsynaptic neuron which interact with specific receptors of presynaptic neuron.
(iv) Neurons releasing acetylcholine are described as cholinergic neurons and those releasing noradrenaline are described as adrenergic neurons.
(v) Refractory period is the period after the transmission of an impulse in a nerve fibre in which membrane of the axon regains its ability to transit impulses.
