(A) Axon terminals form synapses with the dendrites of adjacent neurons. When a nerve impulse reaches the axon terminal,it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters bind to receptors on the post-synaptic membrane of the adjacent neurons. This process allows the signal to be transmitted to all neurons that have a synaptic connection with the presynaptic axon terminal. Therefore,the nerve impulse will travel into all four neurons.

Class 11 Biology Neural Control and Coordination Transmission of Impulses

Medium

Suppose the terminal ends of an axon are in contact with the dendrites of four adjacent neurons,the nerve impulse of the axon will

A
Travel in all the four neurons
B
Get distributed in all the four neurons resulting in a weak impulse
C
Travel only in one neuron which is in closest contact and with the same intensity
D
Travel in none of the neurons because the impulse travels from dendrites of one neuron into the axon of another neuron
