Neurons are pathways for electrical messages to pass through. Their main function is to pass a message from one neuron to another. As a whole, they transmit these messages between a receptor (something that picks up a stimulus. A stimulus includes things such as temperature, pressure, pain etc.), the brain and an effector (something which carries out the response to the stimulus).
There are three main types of neurons:
Sensory neurons - receive message from receptor and transmit it to the ->
Interneurons - receive message from sensory neurons and pass it on to the brain*. The brain responds and the interneurons pass the message on to the ->
Motor neurons - receive message from interneurons and pass it on to an effector.
*In the case of a reflex arc, where there is an unconscious response (e.g. touching a hot object) the message will bypass the brain and go straight from receptor to sensory to interneuron to motor to effector.

How many neurons between the central nervous system and the visceral effector?

Which organ system coordinates the actions of the body?
That would be the nervous system, specifically the Central Nervous system, more commonly abbreviated to CNS.
How many neurons are used outside the CNS in the somatic nervous system?
one
The motor pathway of the autonomic nervous system usually involves how many neurons?
The motor pathway of the autonomic nervous system typically involves two neurons: a preganglionic neuron that originates in the central nervous system and a postganglionic neuron that extends to the target tissue or organ.
How many division are there of the nervous system?
The autonomic nervous system is responsible for the control of the functions of the internal organs and it has two divisions. These are the sympathetic nervous system and the parasympathetic nervous system.
What cells transmit and receive impulses?

Definition of nervous system?
The nervous system is a network of specialized cells that communicate information about an animal's surroundings and itself. It processes this information and causes reactions in other parts of the body. It is composed of neurons and other specialized cells called glia, that aid in the function of the neurons. The nervous system is divided broadly into two categories: the peripheral nervous system and the central nervous system. Neurons generate and conduct impulses between and within the two systems. The peripheral nervous system is composed of sensory neurons and the neurons that connect them to the nerve cord, spinal cord and brain, which make up the central nervous system. In response to stimuli, sensory neurons generate and propagate signals to the central nervous system which then processes and conducts signals back to the muscles and glands. The neurons of the nervous systems of animals are interconnected in complex arrangements and use electrochemical signals and neurotransmitters to transmit impulses from one neuron to the next. The interaction of the different neurons form neural circuits that regulate an organism's perception of the world and what is going on with its body, thus regulating its behavior. Nervous systems are found in many multicellular animals but differ greatly in complexity between species
What are the 4 nerve cell in your body?
There are many types of cells associated with the nervous system. Examples are:Neurons (the functional unit of nervous system). There are many types of neurons as well.OligodendrocyteSchwann cells
How many neurons does a dust mite have?
A dust mite, being a microscopic arachnid, has a very simple nervous system compared to more complex organisms. It typically has around a few hundred to a few thousand neurons, which are responsible for basic sensory functions and motor control. These neurons help the dust mite navigate its environment, find food sources, and avoid predators.
