The basic structure of nervous tissue that responds to environmental changes by transmitting impulses is the

Out of the following given choices;

A. dendrite.

B. Neuron.

C. axon.

D. neuroglia.

The answer is; B

The basic structure of a neuron is given in the attached image. Input signal coming into a neuron do so through the dendrites that may receive many thousands of input signals. The summation of these signals determine whether there will be the transmission of an impulse on the neuron, that is when the threshold potential is reached. This impulse travels through the axon and into the axon terminals and into the synapse that transmits the impulse to the next neuron.

structure is maintained and sustained by:

-cytoskeleton: gives cells coherence

-cell wall: support

-cytoplasm: shape
