Afferent neurons carry information from sensory receptors of the skin and other organs to the central nervous system (i.e., brain and spinal cord), whereas efferent neurons carry motor information away from the central nervous system to the muscles and glands of the body.
The main difference between afferent and efferent is that afferent refers to the neurons carrying signals from sensory perceptions towards the CNS while efferent refers to the neurons carrying signals from the CNS to the effector organs.
Key Terms. efferent: Efferent neurons transmit signals from the central nervous system to the effector cells (e.g. motor neurons). afferent: Afferent neurons convey information from tissues and organs into the central nervous system (e.g. sensory neurons).
A good way to remember afferent vs. efferent neurons is: Afferent Arrives, Efferent Exits. Afferent neurons are neurons whose axons travel towards (or bringing information to) a central point, while an efferent neuron is a cell that sends an axon (or carries information) away from a central point.
The afferent or sensory nerve transfers the messages or signals from various organs to the spinal cord or brain. In contrast, efferent nerve or motor nerve transfer the messages or signals from the spinal cord or brain to multiple organs.
Neurons are unique in their ability to receive and transmit information. Neurons are characterized by the long processes which extend out from the cell body or soma. Dendrites receive afferent signals. Axons carry efferent signals.
Modalities or functions of the cranial nerves are categorized as sensory (afferent) or motor (efferent). These modalities can be further subdivided into subcategories based on each nerve's ...

Afferent neurons transmit information from sensory receptors in the skin and various organs into the central nerve system (i.e. brain, brain, and the spinal cord) and efferent neurons transfer motor information away of the central nervous system and to glands and muscles in the body.
Efferent neurons – also known as motor neurons, carry instructions from the brain to the muscles and glands. Think of them as outgoing mail, delivering commands on what actions our body should take. Afferent neurons – or sensory neurons if you prefer, do just the opposite.
