Detailed explanation-1: -A somatic reflex is an involuntary movement in response to a stimulus. To produce the action, the somatic reflex arc is activated when a signal from the stimulus is sent to the muscle cells, passing through afferent neurons to the CNS, and finally, to the efferent neurons.

Detailed explanation-2: -The somatic reflex arc is the neural pathway resulting in involuntary actions, also known as reflexes. An afferent sensory neuron receives some sort of sensory input or stimulus and transmits it toward the integration center.

Detailed explanation-3: -Skeletal muscle contraction is voluntary and under the regulation of the somatic nervous system. Each skeletal muscle cell is innervated by a motoneuron, and each muscle fiber behaves as a single unit. Smooth muscle, on the other hand, is involuntary and under the regulation of the autonomic nervous system.

Detailed explanation-4: -Somatic reflexes involve stimulation of skeletal muscles by the somatic division of the nervous system.

Detailed explanation-5: -In contrast, somatic reflexes involve unconscious skeletal muscle motor responses. In doing so, these reflexes utilize some of the same lower motor neurons (alpha motor neurons) used to control skeletal muscle during conscious movement.
