How does nervous communication differ from hormonal communication in animals?
1 Answer
They differ in the way they are conducted through the body.
Explanation:
Nervous communication involves an impulse (action potential) moving from one neuron to another, from the axon terminals of one neuron to the dendrites of the next neuron via a synapsis, which is a space between the terminal axons and the dendrites of the next neuron. The axon terminals send neurotransmitters into the synapse, which will transfer the action potential to the dendrites of the next neuron (an interneuron), or to receptors on muscle cells, sensory organs, and glands.
Hormonal communication occurs when endocrine glands secrete specific hormones (chemical messengers) into the bloodstream that travel to cells containing receptor molecules on the surfaces of the cells. Not all cells have receptors for all hormones.
