4 Fast Facts about the Somatosensory System NCCIH

WebThe sensory-somatic nervous system is made up of cranial and spinal nerves and contains both sensory and motor neurons. Sensory neurons transmit sensory information from the skin, skeletal muscle, and sensory organs to the CNS. Motor neurons transmit messages about desired movement from the CNS to the muscles to make them contract. The symptoms of somatic nervous system problems depend on the types of nerves affected. Damage to motor nerves affects your muscles by causing: 1. Cramps, spasms, tremors or twitches. 2. Wasting (shrinking of muscles). 3. Loss of control.

Somatic Nervous System: Definition, Function & Example

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).
