DOWNLOAD PDFThe integration of reflex arcs happens in the spinal cord rather than in the brain, allowing reflexes to occur quickly and without conscious thought.
Afferent sensory neurons receive sensory input and transmit the signal on toward the integration center.
The interneurons are located in the spinal cord and process the signal from the sensory neuron. They then pass the signal on to the effector side of the pathway without going to the brain for processing.
Efferent motor neurons receive the signal from the interneuron and transmit it to the effector target cells, often muscle cells. For example, in the patella-tendon reflex, the effector target cells are muscle cells located near the knee.
The effector targets are the cells that act. They are often muscle cells, and are the terminal cells in reflex arcs.
Picmonic's rapid review multiple-choice quiz allows you to assess your knowledge.
