Parts of a Reflex Arc

Receptor -- receptor end of a dendrite or a specialized receptor cell in a sensory organ -- senses specific type of internal or external change

Sensory Neuron -- dendrite, cell body, and axon of a sensory neuron -- carries information from receptor to brain or spinal cord

Interneuron -- dendrite, cell body, and axon of a neuron in the brain or spinal cord -- carries information from sensory neuron to motor neuron

Motor Neuron -- dendrite, cell body, and axon of a motor neuron -- carries instructions from brain or spinal cord out to effector

Effector -- muscle or gland -- responds to stimulation or inhibition by motor neuron -- produces reflex or action

Sensory Neuron: 1- Afferent Neuron – Moving away from a central organ or point 2- Relays messages from receptors to the brain or spinal cord

Sensory neurons are nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical impulses. For example, some sensory neurons respond to tactile stimuli and can activate motor neurons in order to achieve muscle contraction. Such connections between sensory and motor neurons underlie motor reflex loops and several forms of involuntary behavior, including pain avoidance. In humans, such reflex circuits are commonly located in the spinal cord.
