Somatic reflex refers to a reflex induced by stimulation of somatic sensory nerve endings while the visceral reflex refers to a reflex mediated by autonomic nerves and initiated in the viscera. Besides, both produce a rapid, involuntary, and predictable response in response to a specific stimulus.ĭifference Between Somatic and Visceral Reflex Definition.Also, the five components of each reflex arc are the sensory receptor, sensory neuron, integration center, motor neuron, and effector target.Generally, they use the efferent pathway for their output while they receive sensory signals through the afferent pathway.Therefore, both types of reflexes occur before the information reaches the brain. Both reflexes start from the spinal cord.Somatic and visceral reflex are two types of reflex arcs or nerve circuits which coordinate the function of different effector organs.Similarities Between Somatic and Visceral Reflex Flexor reflex – it is responsible for the pulling out of the body parts in response to a hot stove.It is a type of monosynaptic reflex therefore, it is rapid. Stretch reflex – it is responsible for the stretch of the skeletal muscles.Below are some examples of somatic reflexes. Here, it uses alpha motor neurons, which control the voluntary muscular movements. Somatic reflex is the reflex of the somatic nervous system, which produces unconscious motor responses in skeletal muscles. – Comparison of Key Differences Key TermsĪutonomic Nervous System, Skeletal Muscles, Smooth Muscle Contractions, Somatic Nervous System, Somatic Reflex, Visceral Reflex What is the Difference Between Somatic and Visceral Reflex What are the Similarities Between Somatic and Visceral ReflexĤ. Both types of reflexes are important for the coordination between the central nervous system and the effector organ. Somatic and visceral reflex are two types of reflex arcs or nerve circuits produced by the different systems of the peripheral nervous system. Furthermore, the somatic nervous system produces somatic reflexes while autonomic nervous system produces visceral reflexes. The main difference between somatic and visceral reflex is that the somatic reflex occurs in skeletal muscles whereas, the visceral reflex occurs in soft tissue organs.
