Neurons are classified functionally according to the direction the action potential travels relative to the ____________ . Affer
ent neurons are the neurons of the sensory nervous system. They are responsible for conducting ____________ input from both somatic sensory and visceral sensory receptors.
Neurons is the structural and functional unit of the nervous system. The nervous system is divided into two main parts - central nervous system and peripheral nervous system.
The central nervous system constitute the brain and spinal cord. The CNS contains both the afferent and efferent neurons depending on the direction of their signal transmission. Afferent or sensory neurons are responsible for the conduction of sensory input from the sensory receptors.
