Although these are multipolar neurons, not all of their processes appear in a single plane of section. The other morphological element that defines this type of cell is the presentation of numerous dendrites. They are multipolar in structure. Neurons contain some specialized structures (for example, synapses) and chemicals (for example, neurotransmitters). Neurons are able to respond to stimuli (such as touch, sound, light, and so on), conduct impulses, and communicate with each other (and with other types of cells like muscle cells). are multipolar. A neuron is a single nervous system cell that receives, processes, and transmits electrochemical messages from and to other cells. When Vladimir Putin described the breakup of the Soviet Union several years ago as "the greatest geopolitical catastrophe" of the 20th century, his words triggered a strong reaction in the West and among Russia's neighbors. The Neuron. Bipolar neuron has one axon and one dendrite. the number of processes attached to the cell body, neurons are classified into three types. This type of neuron can't produce action potentials, but what happens is that it undergoes local potentials, or grades potentials. That's the basic classification of neurons. Multipolar neurons - lots of dendrites and one axon Think about the neurons you created on . Multipolar neurons: These neurons are able to receive impulses from multiple neurons via dendrites. The axon of a neuron can be long (from a few centimeters to a few tens of centimeters): it is the type I Golgi neuron. It is an electrically excitable cell. There are three main types of neurons in the body; Sensory neurons - sense changes in the environment. Each multipolar neuron contains one axon and multiple dendrites. An example of a bipolar neuron is a retinal bipolar cell, which receives signals from photoreceptor cells that are sensitive to light and transmits these signals to ganglion cells that carry the signal to the brain.
