How is nerve cell specialised
WebNeurons need to be able to rapidly transmit electrical impulses along their length. They also need to exchange signals with neighbouring neurons across the gaps, known as synapses, that separate them. To acheive these functions, nerve cells have several adaptations. The axon, the long, thin part of the neurone along which the impulse passes, is ... WebThe muscle cells help make up muscle tissue which helps the body move and neurons or nerve cells make up nervous tissue that helps the organism process information. So what are the key takeaways about cell specialization? Number one, cells are the fundamental unit of life. They're the smallest structural and functional unit of an organism.
