What does a multipolar neuron look like?
Multipolar neurons are the most common type of neuron. Each multipolar neuron contains one axon and multiple dendrites. Multipolar neurons can be found in the central nervous system (brain and spinal cord). The Purkinje cell, a multipolar neuron in the cerebellum, has many branching dendrites, but only one axon.
What type of tissue is multipolar neuron?
Multipolar neurons are all of the neurons that are not unipolar or bipolar. They have one axon and two or more dendrites (usually many more). With the exception of the unipolar sensory ganglion cells, and the two specific bipolar cells mentioned above, all other neurons are multipolar.
How do you identify a multipolar neuron?
They possess a single axon with several symmetrically radiating dendrites. Some neurons have multiple axons or lack axons all together. Multipolar neurons can be classified on the basis of their dendritic branching pattern and shape of the soma into stellate, pyramidal, fusiform, Purkinje, and glomerular cells.
What type of tissue is giant multipolar neuron?
Multipolar neurons constitute the majority of neurons in the central nervous system. They include motor neurons and interneurons/relaying neurons are most commonly found in the cortex of the brain and the spinal cord….

What is nervous tissue with diagram?
Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. The cells in nervous tissue that generate and conduct impulses are called neurons or nerve cells. These cells have three principal parts: the dendrites, the cell body, and one axon.
Where is bipolar neurons found?
retina
Bipolar cells (BCs) are the central neurons of the retina which carry light-elicited signals from photoreceptors and horizontal cells (HCs) in the outer retina to amacrine cells (ACs) and ganglion cells (GCs) in the inner retina.
What is unique about bipolar neurons?
The specific location of the bipolar cells allow them to facilitate the passage of signals from where they start in the receptors to where they arrive at the amacrine and ganglion cells. Bipolar cells in the retina are also unusual in that they do not fire impulses like the other cells found within the nervous system.
