Action potentialaction potential
A receptor (protein) on a neuron that receives stimulus (light, pressure, chemical...etc). The stimulus generates a receptor potential (local disturbance/slight depolarization in membrane potential).
Action potentials are found on muscular or neural cells. The propagate along the cells's membrane surface.
Neural networks have nothing to do with neutrons.

When the neural membrane (neurolemma) is at rest it is said to have resting potential, polarized, and has a negative charge inside.
effectors
the conduction of neural information to the muscle fiber
ACH receptors can be defined as an integral membrane protein that responds to the binding of acetylcholine, a neuoyansmitter. Two example are nicotinic acetyl line receptors and muscarinic acetylcholine receptors. .
Action potentials are found on muscular or neural cells. The propagate along the cells's membrane surface.
In the 3rd week of pregnancy called gastrulation, specialized cells on the dorsal side of the fetus begin to change shape and form the neural tube.
The nervous system conducts electrical signals from one structure to another. For example from the brain to the muscles for movement.
The functions can vary greatly, the fact that its an integral protein limits the functions but there are still many different functions. Ill go through a few functions of integral transmembrane proteins. Transportation. Integral proteins can transport molecules and ions through the membrane, facilitated or active transport are two such transport functions. The protein can also act as ion channels which help the cells to keep the ion gradient at a good level (varies greatly for different ions). The protein can also act as receptors for different hormones or neural signals. The integral proteins can also be cytoskelleton, which function is to connect different cells to eachother, or they can be flagells, villi or microvilli.
simple automatic, inborn response to a sensory stimulus
microorganisms do not have the specialized neural systems he way that higher animals do, so they do not 'think' in the conventional sense of the term. Many of them, however, are capable of responding to stimuli and reacting to their environment.
