![]() ![]() Sensory neurons with cell bodies in the dorsal root ganglia of the vertebrate spinal cord are pseudo-unipolar: one branch projects to the periphery (to sensory receptors in the skin, joints, and muscle), the other to the spinal cord. Pseudo-unipolar neurons initially develop as bipolar cells, but at some point the two processes that extend from the cell body fuse to form a single neurite. As an adjective pseudounipolar is (anatomy) of a neuron, having one axon that is split into two branches. Some vertebrate sensory neurons are classified as pseudo-unipolar. Axon vs Pseudounipolar - What's the difference axon pseudounipolar As a noun axon is axon. Examples of bipolar neurons include most invertebrate sensory neurons and bipolar cells of the vertebrate retina. Some neurons in the vertebrate brain have a unipolar morphology: a notable example is the unipolar brush cell, found in the cerebellum and granule region of the dorsal cochlear nucleus.Ī third morphological class, bipolar neurons, extend just one axon and dendritic process from the cell body. In multipolar neurons, multiple processes extend from the cell body including dendrites and axons. Most neurons in the central nervous systems of vertebrates, including mammals, are multipolar. The cell bodies of invertebrate unipolar neurons are often located around the edges of the neuropil, in the so-called cell-body rind. Most neurons in the central nervous systems of invertebrates, including insects, are unipolar. Pseudounipolar neurons are sensory neurons that have no dendrites, the branched axon serving both functions. This section shows a thick section from the cerebral cortex, stained using Golgi-Cox method, which stains neurons black. multipolar (the commonest) - most motor neurons are multipolar. branch ( dendrite ) and a central extension serving as an axon. The neurite then branches to form dendritic and axonal processes. 1 Structure A pseudounipolar neuron has one axon that projects from the cell body for relatively a very short distance, before splitting into two branches. pseudounipolar (single axon and dendrite arise from a common stem) - the primary general sensory neurons are usually pseudounipolar. Initial part of coiled single process Pseudounipolar neuron Figure 2.13 Photomicrograph. A unipolar neuron is a neuron in which only one process, called a neurite, extends from the cell body. ![]()
