The cell body is the main part of a neuron. It may appear round, oval, star-shaped, triangular, pointed or triangular in shape. Its diameter is 5-120 micrometers. It consists of plasma membrane, cytoplasm and nucleus. Cytoplasm of neuron is called neuroplasm. Neuroplasm contains mitochondria, Golgibodies, neurofibrils, ribosomes, endoplasmic reticulum, lysosomes, glycogen and numerous Nisal granules. Polyribosomes join to form Nisal granules. Nisal seeds produce protein.
