Neuron
This image illustrates the parts of a neuron. The dendrites receive incoming signals while axons propagate signals away from the neuron cell body. The myelin sheath surrounds and insulates the axon.
This image illustrates the parts of a neuron, depicted as a nucleus surrounded by a randomly shaped cell body with many arm-like dentrites on its edges. The dendrites receive incoming signals. The axons send signals away from the neuron cell body, represented as beads on a chain in the picture. The myelin sheath surrounds and insulates the axon beads, the node of Ranvier links each axon to the next one, and the Schwann cells inside each axon increase the speed of the signal as it moves towards the axon terminal. The axon terminal is shown as several branches emerging from the last axon in the chain.
