Question

how does the nervous tissue cause action.

Answer 1

Nervous Tissue has an ability to generate an electrical impulse in response to stimuli and to rapidly transmit the electrical impulse from the site of the origin along their length in a particular direction.

Nervous tissue is composed of neurons, which transmit impulses, and the neuroglia, which assist propagation of the nerve impulse as well as provide nutrients to the neuron.
