Parts of the nerve cell and their function

If you were someone who understood brain anatomy and were to look at the brain of an animal that you had never seen before, you would nevertheless be able to deduce the likely capacities of the animal. This is because the brains of all animals are very similar in overall form. In each animal the brain is layered, and the basic structures of the brain are similar (see ). The innermost structures of the brain—the parts nearest the spinal cord—are the oldest part of the brain, and these areas carry out the same the functions they did for our distant ancestors. The “old brain” regulates basic survival functions, such as breathing, moving, resting, and feeding, and creates our experiences of emotion. Mammals, including humans, have developed further brain layers that provide more advanced functions—for instance, better memory, more sophisticated social interactions, and the ability to experience emotions. Humans have a very large and highly developed outer layer known as the (see ), which makes us particularly adept at these processes.

Relationship Between Structure and Function of a …

To support the general function of the nervous system, neurons have evolved unique capabilities for intracellular signaling (communication within the cell) and intercellular signaling (communication between cells). To achieve long distance, rapid communication, neurons have evolved special abilities for sending electrical signals () along axons. This mechanism, called , is how the cell body of a neuron communicates with its own terminals via the axon. Communication between neurons is achieved at by the process of .

While there are as many as 10,000 specific types of neurons in the human brain, generally speaking, there are three kinds of neurons: (for conveying motor information), (for conveying sensory information), and (which convey information between different types of neurons). The following image identifies how neurons come in various shapes and sizes. (It is based on drawings made by Cajal.)

What is the content of these predictive signals

While we are considering numbers, it is worth noting that there are as many as 50 times glia than neurons in our CNS! (or ) are the cells that provide support to the neurons. In much the same way that the foundation, framework, walls, and roof of a house prove the structure through which run various electric, cable, and telephone lines, along with various pipes for water and waste, not only do glia provide the structural framework that allows networks of neurons to remain connected, they also attend to the brain's various house keeping functions (such as removing debris after neuronal death).

are the basic information processing structures in the CNS. Everything occurring the level of neurons qualifies as information processing too. But nothing the level of neurons does. We shall ignore that this view, called the , is somewhat controversial. What isn't controversial is that the function of a neuron is to receive INPUT "information" from other neurons, to process that information, then to send "information" as OUTPUT to other neurons. ( are connections between neurons through which "information" flows from one neuron to another.) Hence, neurons process all of the "information" that flows within, to, or out of the CNS. All of it! All of the information through which we are able to move; all of the information through which we are able to see, to hear, to smell, to taste, and to touch; and of course all of the information through which we are able to reason, to think, to dream, to plan, to remember, and to do everything else that we do with our minds. Processing so many of information requires many types of neurons; there may be as many as 10,000 types of them. Processing so information requires a lot of neurons. How many? Well, "best estimates" indicate that there are around 200 billion neurons in the brain alone! And as each of these neurons is connected to between 5,000 and 200,000 neurons, the number of ways that information flows among neurons in the brain is so large, it is greater than the number stars in the entire universe!

The cell body (soma) is the factory of the neuron

It is important to have an understanding of how the brain functions and which parts control our functioning and behaviour. For example, when a casualty suffers from a stroke, the part of the brain that is affected controls function. If it is the frontal lobe, speech, thought and movement may be affected.

As messages travel from one neuron to the next they move across a synapse. At each synapse there is a chemical called a neurotransmitter. At various parts of the body specific neurotransmitters facilitate communication, for example dopamine (motor function), serotonin (mood) and endorphins (painkillers). Sensory neurons carry messages from a receptor to the brain. The brain then interprets the message. Motor neurons then send the message to an affector in muscles and glands.

Function. Spindle neurons are relatively large cells that may allow rapid communication across the relatively large brains of great apes, elephants, and cetaceans.

The nervous system is composed of more than 100 billion cells known as . A is . As you can see in , neurons are made up of three major parts: a cell body, or , which ; a branching treelike fiber known as the , which ; and a long, segmented fiber known as the , which .
