WebFive Components of the Reflex Arc: 1. receptor 2. afferent pathway (sensory neurons) 3. integration center 4. efferent pathway (motor neurons) 5. effector Reflex Arc the … WebThe first part of a reflex arc is a sensory input from the environment, like touching a hot stove. This sensory information is then relayed through at least one afferent neuron. The information travels through a neuron as a result of action potentials, which are electrical signals that occur due to ion movement in and out of the neuron.

A sensory receptor (dendrite) - detects stimulus 2. A sensory neuron passing into the spinal cord - transmits afferent impulse to CNS 3. An integrating center (within the spinal cord or brain) – 1 or more synapses in the CNS 4. A motor neuron leaving the spinal cord – transmits efferent impulse to effector organ 5.
