Nerve fibres. Light micrograph of a section through a bundle of myelinated axons. Axons are nerve cell processes that transmit nerve impulses away from the cell body. They eventually terminate in a synapse with another nerve cell or with an effector organ,for example a muscle cell where the impulse causes a response. Myelinated axons have a myelin sheath (dark blue) that is produced by associated Schwann cells. The myelin sheath causes impulses to be transmitted faster than in unmyelinated axons.
