1 Efferent neurons (also called motor neurons) carry signals from the gray matter of the CNS through the nerves of the peripheral nervous system to effector cells. 2  The effector may be smooth, cardiac, or skeletal muscle tissue or glandular tissue. Afferent, Efferent, and Mixed Nerves. 2  Some of the nerves in the body are specialized for carrying information in only one direction, similar to a one-way street. 3  Nerves that carry information from sensory receptors to the central nervous system only are called afferent nerves.
This sheath is called the myelin sheath and is made up of Schwann cells in the peripheral nerves and oligodendrocytes in the central nervous system nerves. This insulation can be damaged by compression just as the nerve membrane itself can be injured.he central nervous system nerves are supported by âassistant cellsâ called oligodendrocytes and the peripheral nervous system nerves are support byâ assistant cellsâ called Schwann cells. There are marked differences between the two types of nerves.
