Zoology - Neural Control and Coordination Question with Solution | TestHub
Which of the following statements regarding impulse transmission is incorrect?
I. Chemicals called neurotransmitters are involved in impulse transmission across the synapses.
II. The membranes of the pre-synaptic and post-synaptic neuron are separated by an empty space called the synaptic cleft.
III. The released neurotransmitters bind to the specific receptors present on the pre-synaptic membrane.
IV. The new potential which develops is always excitatory.
Options:
Answer:
Solution:
Chemicals called neurotransmitters are involved in the transmission of impulse across the synapses. The membranes of the pre-synaptic and post-synaptic neuron are separated by a fluid-filled space called the synaptic cleft. The released neurotransmitters bind to the specific receptors present on the postsynaptic membrane. The new potential which develops may be excitatory or inhibitory.
