![]() An example of a multipolar neuron is a Purkinje cell in the cerebellum, which has many branching dendrites but only one axon. The pseudounipolar neurons are sensory in nature, and the axonal processes receive and transmit the information. A pseudounipolar neuron can be found in both vertebrates and invertebrates. Pseudounipolar neurons initially have one structure extending away from soma, but are branched later into two different structures. Multipolar neurons can be found in the central nervous system (brain and spinal cord). The axon is relatively short, and the neuronal cell body usually lacks dendrites. Dendrites are highly branched throughout their length. The thickness of axon is uniform throughout the length. Dendrites are comparatively shorter (usually under 1.5 mm) 4. As an adjective pseudounipolar is (anatomy) of a neuron, having one axon that is split into two branches. Each multipolar neuron contains one axon and multiple dendrites. Axon is comparatively long, sometimes several meters. Multipolar neurons are the most common type of neuron. Multipolar neurons constitute the majority. Note: The majority of neurons in cranial nerve sensory ganglia and the neurons found in the dorsal root ganglia carry information about vibration, proprioception, touch, temperature and pain. These processes are projections from the neuron cell body. Since the dendrite functions as an axon, this action potential does not degrade, but it reaches the axon unabated and continues towards the central nervous system. 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. edit on Wikidata A multipolar neuron is a type of neuron that possesses a single axon and many dendrites (and dendritic branches), allowing for the integration of a great deal of information from other neurons. A bipolar neuron has one axon and one dendrite extending from the soma. These neurons are not found in vertebrates but are found in insects where they stimulate muscles or glands. ![]() Unipolar neurons have only one structure that extends away from the soma. \) illustrates these four basic neuron types. ![]()
