![]() ![]() The example of reflex action is the �knee-jerk� response to the stimulus of the patellar ligament in the knee. The motor neuron response is �hard-wired� for the specific stimulus practically.And for the most voluntary muscle contraction, the impulse originates in the brain or brainstem, and reflex action brought about with only single sensory and motor neuron which synapse in the body part of the spinal cord.The reflex arcs occur in the result of an extremely quick response in muscle contraction to a stimulus, with the minimal intervention from the brain.Reflex Arcs and the Somatic Nervous System: In addition, the Somatic Nervous System also mediates the subset of involuntary muscle responses, known as �reflex arcs�.So, the primary function of the Somatic Nervous System (SoNS) is to create a connection between the Central Nervous System (CNS) and striated muscles to enable complex movement and complex behavior.This response refers to the location and strength of the muscle contraction toward the different parts of the body. The spinal cord and brain process the input from the variety of sources and integrate them before a response devising.The Somatic Nervous System (SNS) consists of both afferent nerves which travel toward the Central Nervous System (CNS) and the efferent nerves are responsible for sending the electrochemical signals toward the rest of the body.The Nerve cell body is present within the system, and also the nerve fiber then comes and terminates within the skin, sense organs, or muscles. The neurons which made the somatic nervous system develop superficially from the structure and connect to the muscles of the body, and carry signals from muscles and sensory organs back to the central nervous system or CNS. Motor Neurons, additionally called efferent neurons, are accountable for carrying the information or data from the brain and spinal cord to muscle fibers throughout the body. Sensory Neurons, additionally called afferent neurons, are accountable for carrying the information or data from the nerves to the Central Nervous System (CNS). The somatic nervous system contains two major forms of neurons: The term “somatic nervous system” is drawn from the Greek word soma, which suggests “body,” that is suitable for considering it’s the only technique that transmits the information or data to and from the Central Nervous System (CNS) to the other parts of the body. ![]()
