![]() These types of neurons are mostly found in the retina of the eye. At the end of one side is the axon, and the dendrites are on the other side. Bipolar neurons have two extensions extending from the cell body. Usually only found in invertebrate species, these neurons have a single axon. This is the most common form of neuron in the central nervous system. These neurons have a single axon and symmetrical dendrites that extend from it. Each combines several elements of the basic neuron shape. However, there are five major neuron forms. Given the sheer number of neurons, there are thousands of different types, much like there are thousands of species of living organisms on Earth. Neurons vary in structure, function, and genetic makeup. These cells have highly developed dendritic trees which allow them to receive thousands of signals. For instance, Purkinje cells are a special type of neuron found in a part of the brain called the cerebellum. How many they have generally depends on their role. Neurons can have more than one set of dendrites, known as dendritic trees. Like antennae, dendrites receive and process signals from the axons of other neurons. Dendritesĭendrites are fibrous roots that branch out from the cell body. Myelin helps axons to conduct an electrical signal. Many axons are insulated with a fatty substance called myelin. It joins the cell body at a specialized junction called the axon hillock. AxonĪn axon is a long, tail-like structure. It’s enclosed by a membrane that both protects it and allows it to interact with its immediate surroundings. Like other cell bodies, a neuron’s soma contains a nucleus and specialized organelles. The cell body contains genetic information, maintains the neuron’s structure, and provides energy to drive activities. Cell bodyĪlso known as a soma, the cell body is the core section of the neuron. However, nearly all neurons have three essential parts: a cell body, an axon, and dendrites. There are two main ways you could answer and you don't have to be speificly how I do it as long as people can understand it doesn't really matter (but it is nice to make it easy for the eyes to read).Neurons vary in size, shape, and structure depending on their role and location. Or you can scroll up and look at the question and answer ABCD format A at the top D at the bottom and maybe clarify that you did that so everyone knows. Or question 1: or even that but with periods instead of colons You can either name the answers to the question or use ABC based on the format of the person (in this case its "Need answers.") who answered the question so if the correct answers are (i don't know if this is the correct answers but this is just an example) if the answer is "It is the part of the neuron that carries information away from the cell body." then you would do eitherġ:It is the part of the neuron that carries information away from the cell body. Which component of the nervous system is the last to be involved in this process? (1 point) A signal passes through many parts of different neurons to make this happen. You see a mosquito land on your hand and swat at it. Hat part of the nervous system is completely protected by bone? (1 point) Motor neurons signal for the body to move the signal toward them ![]() ![]() Through interneurons in the brain and spinal cord that connect sensory neurons and motor neurons Signals move from dendrite to dendrite towards motor neurons ![]() Signals from sensory neurons do not get sent to motor neurons How do signals from sensory neurons reach motor neurons?(1 point) What is the term for changes in the internal or external environment that cause a response? (1 point) It is the part of a neuron that carries information to the cell body. It is a cell that sends signals to the body to move. It is the part of the neuron that carries information away from the cell body. It is a cell that sends signals to the central nervous system based on sensory input. ![]()
