neurobiology

The word 'neurobiology' is a modern scientific compound formed in the 20th century by combining two established Greek-derived elements. The first part, 'neuro-', originates from the Greek neuron, which initially referred to a sinew or tendon but evolved in medical language to denote the nerve fiber. The second part, 'biology', is itself a compound from Greek bios (life) and -logia (a branch of knowledge). Thus, the term's literal construction—'the study of the life/living system of nerves'—logically and precisely defines its modern scope as the comprehensive biological science of the nervous system, integrating its structure, function, and development.

Structure: neuro (nerve) + biology (study of life) - neuro: From Greek neuron (nerve, sinew). A combining form meaning "pertaining to nerves or the nervous system." - biology: From Greek bios (life) + -logia (study, science). A noun meaning "the scientific study of life and living organisms."
