Telodendron

Telodendron (pronunciation: te-lo-den-dron) is a term used in the field of neuroscience to describe the terminal arborization of an axon or a dendrite.

Etymology

The term 'Telodendron' is derived from the Greek words 'telos' meaning 'end', and 'dendron' meaning 'tree'. It is used to describe the tree-like branching structure at the end of a neuron's axon or dendrite.

Definition

A Telodendron is the complex, tree-like structure at the end of a neuron's axon or dendron. It is responsible for transmitting electrical signals to other neurons or to effector cells. The telodendron branches out into several shorter extensions, each of which ends in a synaptic knob or bouton. These knobs are the sites where the neuron can transmit signals to other cells.

Related Terms

  • Neuron: A neuron is a nerve cell that is the basic building block of the nervous system. Neurons are similar to other cells in the human body in a number of ways, but there is one key difference between neurons and other cells. Neurons are specialized to transmit information throughout the body.
  • Axon: An axon is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses away from the neuron's cell body.
  • Dendrite: Dendrites are the segments of the neuron that receive stimulation in order for the cell to become active. They conduct electrical messages to the neuron cell body for the cell to function.
  • Synaptic Knob: A synaptic knob or synaptic terminal is a specialized area within the axon of the presynaptic cell that contains neurotransmitters enclosed in small membrane-bound spheres called synaptic vesicles.
