Reflexes are automatic responses that protect the body and maintain its functions, with somatic and visceral reflexes playing distinct yet complementary roles. This diagram highlights the similarities in afferent inputs and the differences in efferent pathways, showing how somatic reflexes directly connect to skeletal muscle via the ventral horn, while visceral reflexes involve a two-step process through ganglia to target effectors like smooth muscle or glands.

The nervous system is a complex network that governs communication throughout the body, divided into the central nervous system (CNS) and the peripheral nervous system (PNS). This anatomical image highlights key structures such as the brain, spinal cord, ganglion, and nerve, offering a clear view of their roles in coordinating sensory and motor functions. Understanding the distinct yet interconnected components of the CNS and PNS provides valuable insights into how the body processes information and responds to its environment.
