Cell Body (Soma): The cell body contains the nucleus and other organelles necessary for the metabolic activities of the neuron. Dendrites: These are branching extensions that receive signals from other neurons and convey them towards the cell body. Axon: A long, slender projection that transmits impulses away from the cell body to other neurons, muscles, or glands. The axon may be covered by a myelin sheath formed by oligodendrocytes in the CNS and Schwann cells in the PNS, which increases the speed of impulse conduction.
