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.
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.
Afferent and efferent are two terms used in the field of neuroscience to describe the flow of information within the nervous system. Afferent refers to the pathway through which sensory information is transmitted from the peripheral nervous system to the central nervous system.
Afferent neurons are sensory neurons that carry nerve impulses from sensory stimuli towards the central nervous system and brain, while efferent neurons are motor neurons that carry neural impulses away from the central nervous systme and towards muscles to cause movement.
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 ...
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.
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.
