Most axons branch, in some cases very profusely. The end branches of an axon are called telodendria. The swollen end of a telodendron is known as the axon terminal or end-foot which joins the dendrite or cell body of another neuron forming a synaptic connection.
Axons are thin fibers that enable communications between neurons (nerve cells). The function of axons is to transmit information in the form of electrical impulses between neurons. From the broadest perspective, axons act like transmission cables.
1. terminal arbor. The highly branched tree-like structure at the end of an axon that innervates target regions. 2. collateral branch. A branch that extends from the sides of an axon, often interstitially, that can innervate a target by re-branching to form a terminal arbor. 3. cytoskeletal dynamics.
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.
An axon typically develops side branches called axon collaterals, so that one neuron can send information to several others. These collaterals, like tree roots, split into smaller extensions called terminal branches, with a synaptic terminal on the tip.
Axon extension and growth of new telodendrons (and synapses) are guided by several factors, including the nerve growth factor (NGF). The branching processes, in turn, play a role of fundamental importance in neuroplasticity, for instance, in cognitive processes such as memory and learning.
Axon branching connects single neurons with multiple targets, which, along with the formation of highly branched terminal arbors, underlies the complex circuitry of the vertebrate CNS.
The axon terminal, also known as the synaptic bouton and terminal bouton, is the most distal portion of a neuron’s axon and is critical for neural communication. When action potentials reach the axon terminal, calcium floods the neuron, allowing synaptic vesicles to fuse with the membrane and release stored neurotransmitters to target cells.
Axon. Learn about the morphology and histology of neurons, the basic building blocks of the nervous system. Axons are processes from the cell body (soma) or from the axon hillock (a specialized part of the cell body) of a neuron that conduct impulses away from cell body.
Where do axon branches form? The last step of axon development is terminal branching, which allows a single axon to connect to a broad set of postsynaptic targets.
