The pathway of neurons that impulses in an automatic response follow is called the reflex arc. This involves sensory neurons detecting a stimulus, sending a signal to the spinal cord, which then processes the information and sends a response via motor neurons back to the muscles or glands.
Nerve impulses are carried from the central nervous system to the effector organs (muscles or glands) by motor neurons. These motor neurons form a pathway known as the efferent pathway.
The muscle fiber or gland cell that responds to efferent impulses is known as the effector. Effector cells receive signals from motor neurons and carry out the response, such as contracting or secreting a substance. This is part of the efferent pathway in the nervous system that controls the body's actions and functions.
A reflex
Nerve impulses are transmitted from the receptor to the central nervous system via sensory neurons. In the central nervous system, the impulse is processed and may be relayed to motor neurons that carry the impulse to effectors such as muscles or glands to produce a response. This pathway allows for communication and coordination between different parts of the body.
The short pathway of neurons that allows for an automatic response is called a reflex arc. It typically involves a sensory neuron, an interneuron (in some cases), and a motor neuron, allowing for a rapid response to stimuli without involving the brain. This pathway enables quick reactions, such as pulling your hand away from a hot surface. Reflex arcs are crucial for protecting the body from harm.

The classical pathway is part of the adaptive immune response and is triggered by specific antibodies binding to pathogens. The alternative pathway is part of the innate immune response and is activated by the presence of foreign substances on the surface of pathogens.
