Reflex Arc
The nerve impulse travels through the reflex arc. It travels from the sensor through the sensory neurone, through the spinal cord and motor neurone to the effector muscle.
nociceptors and mechanoreceptors (respond to touch, temp and pain)
The short pathway that carries the impulse for an automatic response is called a reflex arc.
The pathway that an impulse travels from your foot back to your leg is an example of a reflex arc. A reflex arc includes a sensory receptor (in this case, a receptor in your toe), sensory neuron, motor neuron, and effector (leg muscle). Some reflex arcs include interneurons. In other reflex arcs, a sensory neuron communicates directly with a motor neuron.

The nerve impulse travels through the reflex arc. It travels from the sensor through the sensory neurone, through the spinal cord and motor neurone to the effector muscle.
A reflex arc doesn't go all the way up to the brain. Thus it NEVER becomes part of the thought process.

They are neurons and not neutrons. You have afferent neuron. Then you have intermediate neuron and then you have the efferent neuron in the reflex arc.

A reflex arc involves the following components:The receptor is the part of the neuron (usually a dendrite) that detects a stimulus.The sensory neuron transmits the impulse to the spinal cord.The integration center involves one synapse (monosynaptic reflex arc) or two or more synapses (polysynaptic reflex arc) in the gray matter of the spinal cord.A motor neuron transmits a nerve impulse from the spinal cord to a peripheral region.An effector is a muscle or gland that receives the impulse from the motor neuron. In somatic reflexes, the effector is skeletal muscle. In autonomic (visceral) reflexes, the effector is smooth or cardiac muscle, or a gland.

Homeostasis works as a negative feedback mechanism, which is a kind of reflex action. When the body detects changes in external/internal environment, the receptor will generate a nerve impulse to the coordination centre and then make a response through effector. This is a reflex arc.
An effector is at the end of a reflex arc as it is the muscle or gland that 'does' the reflex. What the effector does is the outcome of the reflex arc.
