WebJun 14, 2024 · A sensory neuron (sometimes referred to as an afferent neuron) is a nerve cell that detects and responds to external signals. Sensory neurons receive information via their receptors, which are part of the peripheral nervous system, and convert this information into electrical impulses. These impulses act as signals and are passed on to the ... WebThe root cells contribute their axons to the ventral roots of the spinal nerves and are grouped into two major divisions: 1) somatic efferent root neurons, which innervate the skeletal musculature; and 2) the visceral efferent root neurons, also called preganglionic autonomic axons, which send their axons to various autonomic ganglia. 87 henderson street bridge of allan WebA neuron is a single sensory or motor nerve cell, whereas a nerve is a bundle of neuronal fibers (axons). Cranial nerves have three types of sensory and three types of motor neurons, known as modalities. Therefore, a nerve may be composed of a combination of sensory or motor neurons (e.g., the facial nerve possesses sensory and motor neurons).
