Select your answer for: Neuronal metabolic support is sustained primarily through:
Show answer

Answer: A. Cell body or soma

Explanation

The cell body, or soma, contains the nucleus and metabolic machinery. Neuronal metabolic support is sustained primarily through the biochemical activities of the soma. Proteins and energy sources required for neuronal survival originate in the cell body. Neurons require continuous supplies of oxygen and glucose for active metabolic support. The soma houses organelles like mitochondria that generate cellular energy currencies. Cellular health depends on axonal transport systems maintaining communication with the soma.

Neurodegenerative diseases often involve metabolic failure within the neuronal cell body. Studying neuronal metabolism helps researchers develop treatments for brain injuries. Maintaining healthy somatic function is vital for preventing premature neuronal cell death. Dendrites primarily receive incoming electrochemical signals from neighboring neurons. The axon transmits electrical action potentials away from the soma toward synapses. Cytoplasmic fibers provide structural support rather than primary metabolic generation.
