What type of neurons are stellate cells?
Stellate cells are any neuron in the central nervous system that have a star-like shape formed by dendritic processes radiating from the cell body. Many Stellate cells are GABAergic and are located in the molecular layer of the cerebellum.
Do axons have branches?
An axon typically develops side branches called axon collaterals, so that one neuron can send information to several others. These collaterals, just like the roots of a tree, split into smaller extensions called terminal branches.
What is the branching of neurons?
Dendritic arborization, also known as dendritic branching, is a multi-step biological process by which neurons form new dendritic trees and branches to create new synapses. The morphology of dendrites such as branch density and grouping patterns are highly correlated to the function of the neuron.
What neuron has multiple axons?
Multipolar neurons
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.
Where are stellate cells found in cortex?
The majority of cortical neurons are pyramidal cells that are found in layers 2 to 6. Most spiny stellate cells are interneurons that are located in the middle cortical layers.
Why axons have branching at their ends?
The remarkable ability of a single axon to extend multiple branches and form terminal arbors allows vertebrate neurons to integrate information from divergent regions of the nervous system.
How many axons does a bipolar neuron have?
one axon
A bipolar neuron has one axon and one dendrite extending from the soma.
Which neurons are unipolar bipolar and multipolar?
Neurons can also be categorized by the number of processes extending from the cell body. Unipolar neurons have one axon. Bipolar neurons have an axon and one dendrite extending from the cell body toward opposite poles. Multipolar neurons have multiple dendrites and a single axon.
What do stellate cells do?
Stellate cells reside in the liver within the space of Disse, that area between sinusoidal endothelial cells and the surface of hepatocytes, and thereby are intimately associated with both of those cell types. Stellate cells provide the liver with an ability to respond to injury and heal certain types of damage.
