Reflexes anatomy

WebReflexes can be spinal or cranial, depending on the nerves and central components that are involved. The body uses both spinal and cranial reflexes to rapidly respond to important stimuli. All reflex arcs include five basic components; (1) a receptor, (2) a sensory neuron, (3) an integration center, (4) a motor neuron, and (5) an effector. WebReflexes can be classified in many different ways, but we will examine them as either somatic: involving control of skeletal muscle, or autonomic: involving control of smooth muscle, cardiac muscle, glands etc. Regardless of their classification, all reflexes have 5 basic components: 1) A receptor that detects change.
